Because of global climate change events; the quantification of carbon (C) present in different species from diverse ecosystems are urgently needed. Study evaluated the performances of different methods used for the C estimation in different plant components and traits by comparing with harvest method. For this, 117 herbaceous species just-before flowering were harvested from the campus of Banaras Hindu University, Varanasi. Across the components, the mean C contents (g plant-1) varied between 0.33 for roots of procumbent and 7.93 for shoots of native trait categories. On g m-2 basis, it ranged from 29 (roots) to 85 (shoots). Similarly across the components, the mean C: B ratio ranged between 0.41 (roots) and 0.44 (shoots). The linear relationship between C and B had high correlation coefficient, low standard error of estimate together with low discrepancy in extrapolation compared to the other models. Hence, compared to other models, the linear equation could be used in C estimation. Further among all the estimators; at the species, component and functional group levels, the mean C: B (0.43) ratio of the entire herbaceous species resulted as an accurate estimator of the C. Because of its simplicity and low discrepancy, the mean C: B (0.43) ratio seems to be reasonable to estimate the C content based on the known biomass. Stems of perennials, erects, leguminous and native plants had greater C than the others. Thus, the perennial, erect, leguminous and native herbaceous species could be an alternative for reducing the atmospheric C in the tropical grasslands.

Impact of fly ash (FA) on germination and initial seedling growth performance of Leucaena leucocephala (Lam.) de Wit was studied during 2016-2017. Substrate was prepared by admixing FAto forest soil (S) at five concentrations viz.20 %, 40 %, 60 %, 80 % and 100 % (w/w). The experimental design was CRD with six treatment and three replications. Eighteen hundred freshly collected seeds were treated with hot water and sown at 0.5-1.0 cm depth in germination trays containing substrates of different treatments. Significant (P<0.05) variation in germination (G.) period, G. rate, G. capacity and G. Index with respect to FAconcentration in growing media was observed (n=100).G. period was reduced by 5.67 days in 20 % fly ash admixed growing media (FAAGM) over control (S). Maximum G. rate (88.67 %), G. value (18.47) and G. index (1.58) were found in 20 % FAAG Mafter 30 days of sowing. Observations pertaining to growth dynamics were recorded at 90 days after transplanting (DAT). Significant difference (P>0.05) in seedling survival rate, plant height, diameter growth, nodules per plant and seedling quality index were observed. The survival rate (91.83 %) and root nodule number was (7.20) was maximum at 20 % FAAGM. But plant height (51.68 cm), diameter growth (3.96 cm) and seedling quality index (0.706) were attained maximum at 40 % FAAGM. It is concluded form the present investigation that FA can be admixed @ 20 % (w/w)in forest nurseries for improving germination and @40 % (w/w) for promoting seedling growth and quality improvement.

Indian J Ecol 2020, 47(1), 102-8.
Two Experiments were conducted to understand the suitable pre-treatment methods to know the germination behaviour of five selected legume species (Albizia thompsonii, Calopogonium mucunoides, Crotalaria micans, Tephrosia candida, Albizia procera) and their desiccation tolerance. Pre-treatments given were control (no treatment), mechanical scarification (seed coat cutting), H2SO4 (97 %) for different durations (30 sec, 5 min, 15 min and 30 min) and heat scarification 60°C (9, 19 and 24 hours) and 80°C (4, 19 and 24 hours). Out of the 11 pre-treatments tested, conc. H2SO4 and mechanical scarification provided significant results in all the five species. Mechanical scarification provided maximum germination (96.25 %) of C. micans while, conc. H2SO4 treatment for 30 min provided maximum germination of T. candida (97.50 %). Seeds of all species were dried down to the target moisture contents (TMC) of 9, 7, 5, 3 and 2.5 per cent using silica gel for the second experiment to study the effect of seed desiccation on viability of these seeds. The viability of C. mucunoides reduced to 80 per cent at 3 per cent TMC while for T. candida, it was 75 per cent at 5 per cent TMC. In addition, the viability of both the species reduced greatly when dried below 3 per cent TMC. Both species i.e. C. mucunoides and T. candida took 37 days to reach the set TMC of 2.5 per cent using silica gel drying.

Study investigates the effect of pre-harvest calcium nitrate sprays on the qualitative and quantitative characteristics of 'Winter Dawn' strawberries (Fragaria × ananassa Duch.). Strawberry fruits were sprayed with different doses of Calcium nitrate (0.2 %, 0.4 %, 0.6 % and 0.8 %) under field conditions. In comparison tothe control, foliar nutrition with Ca(NO3)2 significantly improved fruit quality and yield related parameters. Calciumnitrate (0.4 %) registered the highest total soluble solids (TSS), total sugars, reducing sugars, non-reducing sugars and -1 ascorbic acid content over the other treatments and the control. Moreover, maximum fruit size, weight and yield plant was also obtained with Ca(NO3)2 at 0.4 per cent. Supplementary calcium feeding played a significant role in enhancing fruit firmness by imparting strength and thickness to fruit cell wall. Therefore, it is intended that foliar feeding Ca(NO3)2 at 0.4 % is the most effective to extend the qualitative and quantitative characteristics of 'Winter Dawn' strawberries.

Instant noodles were prepared by adding spinach puree at 0,10,20,30,40 and 50gm puree per 100 gm flour. The noodles were evaluated for its various quality characteristics viz. cooking quality, proximate constituents and sensorial characteristics; followed by evaluation of its storage quality during the storage of 12 months. The cooking time was reduced drastically with addition of spinach puree in noodles. The cooking loss and swelling index decreased progressively with increase in level of puree in composite flour. Cooking weight increased linearly, protein and fat remained unchanged, whereas ash and fiber increased, and carbohydrates were decreased with increase in level of spinach puree in noodles. The sensory quality with respect to colour, texture and overall acceptability of noodles were improved. Noodles with 40gm puree per 100 gm flour scored highest. The results pertaining to storage studies revealed that moisture content increased significantly and progressively during storage of 12 months in LDPE and HDPE. However, increase in moisture content was more pronounced after 6 months. Peroxide value and free fatty acids were increased marginally during storage in both LDPE and HDPE and the values were within the prescribed limits. There was no yeast and mould growth during 6 months of storage in both the packages. The total plate count increased with increase in the moisture content and it was more pronounced in LDPE as compared to HDPE pouches. The microbial load was well within the tolerable limits during storage.

Walnut is very difficult to propagate and its multiplication is mainly done in the open field conditions, which generally takes two to three years for production of grafted nursery plants. For rapid multiplication of walnut plants, the present study was conducted in polyhouse conditions to standardize the method and time of epicotyl grafting with three methods of epicotyl grafting viz. cleft, wedge and tongue performed on 15,30 and 45-days-old epicotyls. The cleft grafting done on 15-days-old epicotyls gave highest percentage of bud-sprouting (94.66 %), followed by wedge grafting which resulted in 90 per cent success. The highest total linear growth, scion girth and leaf area were produced by wedge method performed on 15-days-old epicotyls. On the basis of two years study, it is concluded that wedge method of grafting on 15-days-old epicotyls is recommended for commercial multiplication of nursery plants of walnut in a year under protective conditions.

Punica granatum is one of the world’s nutritious fruit, tolerating high drought. Bacterial blight is being an obstruct in the export of pomegranate from India. In the present study, a rigorous and efficient protocol for micropropagation of pomegranate plantlets is developed which can replace traditional plant breeding practices. Antioxidants controls polyphenolic exudation in micropropagation. For the first time, this report accomplishes to control polyphenols by modifying medium constituents. Woody plant (WP) medium containing benzyl-amino-purine (BAP) and kinetin (both at 1.5 mg l-1) exhibited high bud break of about 99 %. Further, it gave highest number of shoots of about 6.36 ± 0.22 with the length 6.12 ± 0.31 cm in multiplication stage. Shoots were successfully rooted in WP medium containing indole butyric acid (IBA) 1.5 mg l-1 with 5.62 ± 0.17 roots. This research emphasizes to preliminarily harden plant lets in vitro prior to hardening using innovative technique with increase in gelling strength and by creating nutrient competition. Nutrient stressed plants have a higher survival rate of 98 % and water stressed plants have a survival rate of 96 % when compared to conventional method. Therefore, mass propagation of pomegranate plants is possible to meet the demand of farmers in procuring disease-free plantlets.

The Don-0 and Col-0 ecotypes of Arabidopsis thaliana showed significant phenotypic diversity for several quantitative traits. The phenotypic data taken on hybrid derived from Col-0 x Don-0 and parental lines provides the information of their continuous developmental pattern throughout the life cycle. The developmental data exhibits heterosis for most of the traits (specifically biomass related traits) due to supplementary genetic contributions of both parents. Consequently, the hybrid was found to be more vigorous in comparison to both the parents in terms of all the traits except yield trait. Moreover, higher and lower performance of hybrid causes due to constructive (hybrid vigor) and deleterious epistatic interactions of loci (necrosis: hybrid incompatibility), respectively. The present study also concluded that Don-0 is a slow growing, delayed flowering and high biomass containing ecotype. The shoot and root biomass at initial stage was found to be less in Don-0 than the Col-0 but high at maturity. The present investigation provides the preliminary information which could be utilized for future genetic studies to understand the heterotic phenomenon in Arabidospsis.

Indian J Biotechnol 2020, 19(2), 94-101.
Plant insecticidal proteins like protease inhibitors have been reported to confer insect resistance in transgenic plants. We have cloned a protease inhibitor gene of black gram (Vigna mungo L.) and developed transgenic tobacco plants expressing the protease inhibitor constitutively under the 35S promoter by Agrobacterium tumefaciens mediated genetic transformation. A full-length open reading frame (ORF) of 545 nucleotides codes for a serine protease inhibitor protein with a deduced sequence of 180 amino acids contributing to a predicted molecular mass of 20.2 kDa. The Vigna mungo protease inhibitor (VmPI) is basically a Bowman-Birk type proteinase inhibitor (BBI) of double headed type; family of plant serine protease inhibitors that block trypsin or chymotrypsin. Comparison for conserved domain in the protein by National Centre for Biotechnology Information (NCBI) conserved domain (CD) search showed that the regions from 113-168 amino acid residues have the conserved domain of which 9 residues compose reactive loops on the conserved domain of BBI. The transgenic tobacco plants developed were confirmed by Southern, northern hybridization, polymerase chain reaction (PCR) and reverse transcriptase-PCR (RT-RCR) analysis. When transgenic T1 tobacco plants were analyzed for insecticidal bioassays, the larval growth of Spodoptera litura, the tobacco cutworm was found severely retarded as compared to their growth on control plants. Therefore, black gram protease inhibitor could be used as an alternative individually or in combination with other insecticidal genes for the development of insect-resistant transgenic crop plants.

Indian J Biotechnol 2020, 19(2), 82-93.
Bipolaris maydis causing maydis leaf blight (MLB) is an aggressive fungal pathogen of maize. The present study focused on the responses of certain defence genes in the resistant and susceptible maize inbred lines viz., SC-7 and CM 119, respectively, against MLB and symptom development in the host. Biochemical activity of the PR protein β-1, 3-glucanase and phenylalanine ammonia lyase (PAL) assay, with total chlorophyll content was recorded for both the inbred lines before and after pathogen inoculation. Gene expression was studied by quantitative polymerase chain reaction (qPCR) at different time intervals post inoculation. Differential expression pattern was observed even at the same time point in both the inbred lines. Enhanced expression of the pathogenesis related (PR) protein and phenylalanine ammonia lyase (PAL) enzyme at different time points in resistant lines indicated their association with infection stages of B. maydis and response of the resistant line against disease establishment. Down regulated gene expression of pheophytinase suggests reduced enzyme activity linked with less chlorophyll degradation in the resistant line compared to the susceptible line. This fact directly correlates with symptom development of MLB disease. The present study thus revealed that the expression of defence related genes is aligned with developmental stages of the pathogen to restrict its growth and gene expression of constitutive genes also changes differentially during the disease development in resistant and susceptible lines.

Recurrent surge in demand of multipurpose peppers have positively encouraged pepper breeding community to study diverse aspects of pepper genetics, physiology, breeding and biotic stresses, however research on application of anther culture in pepper is still limited. Current study was aimed to assess the in vitro androgenic response of two prominent Bulgarian pepper varieties in five different duration times (12, 14, 16, 18 and 20 days) on incubation period and regeneration mediums containing kinetin (0.1, 0.2 and 0.3 mg L-1) and combination of zeatin (0.25 mg L-1 0.5 mg L-1) and indole acetic acid (IAA) (0.1 mg L1). Experimental results indicated specific requirements for composition of culture medium and duration time depending on genotype. Prolonged anthers incubation on induction medium had a positive effect on embryo formation and their conversion into plantlets compared to regeneration medium variants. Highest number of embryos and plant-regenerants of variety Stryama was achieved after 18 days incubation period and medium variant containing 0.1 mg L-1 kinetin. Embryo induction in variety Zlaten Medal 7 was higher after 16 days and control medium without plant growth regulators, while regeneration at 20 days also on control medium variant.

Genetic diversity analysis of eighty six Indian wheat genotypes was performed using sodium dodecyl sulphate polyacrylamide gel (SDS-PAGE) electrophoresis based on their total seed storage protein. A dendrogram was constructed using the genetic similarity coefficient matrix based on SDS-PAGE, which categorized these genotypes according to their electrophoretic patterns into eight different clusters. These eighty six genotypes studied here belong to three different species of wheat. Out of these eighty six genotypes, two genotypes belong to T. dicoccum; eleven belong to T. durum and the remaining seventy three belongs to T. aestivum. In the dendrogram, all the eleven genotypes of the species T. durum (A-9-30-1, HD-4672, RAJ-1555, PDW-233, PBW-34, HI-8381, PDW-291, WH-896, PDW-215, HI-8498 and MACS-2846) were grouped in one cluster. The pedigree analysis of genotypes showed similar parentage with the electrophoretic profiling of the different wheat genotypes. From this study, it has been concluded that the total seed storage protein profile of wheat can be used as a marker for genetic diversity.

Serine/Threionine (Ser/Thr) protein kinases are multifarious phosphorylation enzymes which also play a central role in signalling events following pathogen recognition in plants. The present study describes cloning and characterisation of upstream promoter region of a Ser/Thr protein kinase (STPK) gene from Piper colubrinum (PcSTPK), a wild species highly resistant to fungal pathogens in the Piper germplasm. The gene was found to be pathogen responsive when challenged with oomycete pathogen – Phytophthora capsici. Transcript abundance of PcSTPK was determined by quantitative real time-polymerase chain reaction (qRT-PCR) which demonstrated maximum transcript accumulation of PcSTPK in inflorescence, followed by leaf, stem and root tissues. Inoculation of leaf tissues with the oomycete pathogen Phytophthora capsici, also induced significant transcript accumulation of PcSTPK in the plant. Genome walking methodology was adopted to clone upstream promoter elements of PcSTPK. In silico analysis revealed the presence of regulatory elements for light responsiveness, meristem and endosperm expression in addition to various hormone responsive elements. Our results suggest that PcSTPK along with its cis-regulatory elements has a role in modulation of plant stress response.

The present study was aimed to examine the wound healing potential of Juglans regia L. root (JR) in rats by incision and excision wound methods via the anti-inflammatory, antioxidant and antimicrobial activities. We have used tensile strength and biochemical parameters for studying the wound healing properties of JR by incision wound methodology. The anti-inflammatory effect was assessed by the measurement of paw edema in carrageenan-induced inflammation in rats. The wound contraction area, antioxidant status, and antimicrobial studies were exhausted excision wound methodology. There was a significant decrease in percent inhibition of paw edema (0.63 ± 0.03 to 0.33 ± 0.02 after 24 h) with an increase in JR concentration. Tensile strength and hydroxyproline level of different concentrations (1, 2.5, 5, and 10 % w/w) of JR ointment treated groups were found significantly (P <0.001) comparable to the reference group. Moreover, JR showed significant antimicrobial and antioxidant properties, by its ability to increase antioxidant and antimicrobial levels. In conclusion, the overall results obtained in this study clarify that JR inhibits paw edema and accelerates cutaneous wound healing.

Sucrose/H+ Symporter1 (OsSUT1) through refined sequence - template alignment based structural modelling. Indian J Biochem Biophys 2020, 57(3), 283-90.
Sucrose/H+ Symporters (SUTs) play an important role in plant growth and yield. They are involved in long - distance transport of sucrose from source leaves to filling grains of cereals through a process called phloem loading. However, the molecular mechanism of sucrose transport through SUTs is not yet known. Understanding the key residues involved in sucrose transport can be helpful in developing high yielding varieties through genetic engineering, gene editing or allele mining. Here, the molecular model of OsSUT1 developed based on refined target-template alignment using Modeller software provides structural insights on the sucrose transport mechanism. We propose 13 putative sucrose binding residues and 11 putative H+ binding residues involved in sucrose/H+ co-transport in OsSUT1.

Indian J Anim Res 2020, 54(2), 254-8.
Twenty four (24) dairy ewes at the 4th stage of lactation were used to assess the milk production and serum prolactin level of ewes treated with leaf’s powder of Spondias mombin. The lactating ewes were selected and divided into 4 groups of 6 ewes per group: control group (no fed powder of Spondias mombin), Galactin group (no fed powder of Spondias mombin but treated with lactogenic drug) and groups treated with powder of Spondias mombin (group single dose and group double dose). The parameters measured include daily milk production, body weight of lambs and ewes. The resulted outcomes indicate that ewes that received powder of S. mombin and Galactin produced more milk than controls. The average daily increases in milk production were 9.92 %, 14.25 % and 18.88 % in single dose, double dose and Galactin groups, respectively compared to control group. Lamb weight gain was also significantly higher than that in the control group. The treatments did not influence body weight of ewe. The daily weight gain of 93.12; 97.47; 99.07; 86.76 g/day were found in single dose, double dose, Galactin and control groups, respectively. The results of the blood analysis of hormone showed that serum prolactin levels increased in the group treated with powder and Galactin compared to control group.

Indian J Anim Res 2020, 54(2), 196-201.
180-day feeding trial was conducted on the growth performance, feeding efficacy, immunological parameters and gonadal reproductive parameters of common carp, Cyprinus carpio fed with neem (Azadirachta indica) leaf extract (NLE) incorporated at different levels (0, 0.25, 0.5, 1.0, 1.5 and 2.0 g kg-1 feed) in rice bran and mustard meal (1:1 ratio) basal diet. The study revealed highest Net Weight Gain (NWG) in fish fed on NE 1.0 g kg. Results showed that the good growth response was obtained in fish fed with the NLE 1.0 g kg-1 feed and least in fish fed only on basal diet (without NLE). Whereas, higher gonado-somatic index (GSI), relative fecundity and ova diameter values were obtained from fish fed on basal diet while the least were observed from fish fed only on basal diet, while the least value was fish fed with NLE 1.0 g kg-1 feed. Fish fed with NLE 1.0 g kg-1 feed also showed significantly (p<0.05) enhanced phagocytic activity ratio, Phagocytic index, NBT activity, CAT, SOD, GPx and GR responses in comparison with fish fed only on basal diet, where as LPO is significantly decreased on being fed with NLE up to 1g kg-1 feed. The study indicated that incorporation of NLE in feed improved growth, delayed female gonadal maturation and could be used as a potential immunostimulant and to control the prolificbreeding of C. carpio in aquaculture.

Indian J Anim Hlth 2020, 59(1), 45-9.
Dermatophytes are responsible for a majority of superficial fungal infections. They are distinctive from other pathogenic fungi in their ability to use keratin as living. They can sustain in different ecosystems that added in their morphological and ecological range with high flexibility to changing environmental conditions. Lately, Microsporum canis has evolved as a resistant pathogen against several antifungals and has been in the focus of interest for causing outbreaks and epidemics in humans from domestic animals. The increasing evolution of resistance, therapeutic failures, and reduced number of available drugs stimulated to investigate therapeutic alternatives by using some commonly available plants empirically used for their antifungal properties. Likewise, the present study reports the in vitro antifungal efficacy of crude as well as fractionalized extracts with different solvents of Ficus racemosa leaves (L.), Cassia fistula L. and Nerium oleander L. Antifungal activity was evaluated according to Clinical Laboratory Standards Institute (CLSI) protocol by determination of Minimum Inhibitory Concentration (MIC’s) values on a clinical isolate of M. canis that showed resistance to some commonly used antifungals. All crude phyto-extracts except Nerium oleander L. effectively inhibited the growth of M. canis. The methanolic extract of Ficus racemosa L. and Cassia fistula L. completely inhibited the fungal growth at a concentration of 2 µg/mL and 8 µg/mL respectively. These two phyto-extracts proved to have significant antifungal activity against common antifungal resistant M. canis isolate. Further studies with the identified plant parts through in vivo studies and pin-point isolation of the active compound may prove beneficial as an effective alternative therapy for the pathogen.

The efficiency towards nitrogen uptake and its utilization may vary in different sorghum genotypes due to inherited biological nitrification inhibition potential. In this study, four sorghum single cut genotypes (SPH 1890, SPH 1891, CSV 30F and CSV 32F) were grown with three fertility levels (75 % RDF, 100 % RDF and 125 % RDF). The results revealed that higher the fertilization (125 % RDF) higher the biomass yield obtained with improved fodder quality parameters. Sorghum genotype CSV 32F had the highest green and dry fodder yield and it also had better digestibility in comparison to other genotypes. The highest nitrogen uptake was recorded in the genotype SPH 1891 which resulted in higher crude protein yield in this genotype but it noticed to have positive correlation with HCN (anti-nutrient) which is not desirable in livestock feed. In conclusion, use of 125 % RDF and the genotypes CSV 32F would enhance the fodder yield due to comparatively better nitrogen uptake ability and its significant positive correlation with fodder quality parameters and growth attributes.

A field experiment was conducted at the Instructional-cum-Research (ICR) farm, Assam Agricultural University, Jorhat (Assam) during 2016-17. The PRG-1 variety of ryegrass (Lolium multiflorum) was tested at three seed rates and four nitrogen levels. The experiment was laid out in split-plot design in three replicates. The treatments consisted of three different seed rates in main plot viz., 10, 15 and 20 kg/ha along with four nitrogen levels viz., 0, 30, 60 and 90 kg N/ha in subplots. Results revealed that seed rates and nitrogen levels significantly effects ryegrass quality parameters. A seed rate of 20 kg/ha was found to be statistically superior in regards to quality parameters in all the three cuts viz. 1st, 2nd and 3rd cut as compared to seed rate of 15 kg and 10 kg/ ha. The highest crude protein yield (6.21 q/ha) was obtained with seed rate of 20 kg/ha and was significantly superior to 15 kg/ha and 10 kg/ha. The crude protein content, crude fat content, crude fiber content of the ryegrass were also found to be significantly higher in seed rate of 20 kg/ha. In case of nitrogen levels application of 90 kg N/ha resulted in higher values in almost all the quality parameters. The highest crude protein yield (7.43 q/ha) was also obtained in 90 kg N /ha and was significantly superior to all other lower doses of nitrogen (60 kg and 30 kg N/ha). The crude protein content, crude fat content, crude fiber content of the ryegrass were also found to be significantly higher in nitrogen level of 90 kg N/ha.

Forage Res 2020, 46(1), 35-9.
Aim of present investigation was to assess genotype environment interaction and determine stable oat (Avena sativa L.) cultivar in central Uttar Pradesh under diverse environment for seed yield and its components in 25 genetically diverse genotypes using randomized block design with three replications during winter season of 2016 -17 and 2017-18 at Students Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U. P.) during rabi 2016-17 to 2017- 18. There was considerable variation in seed yield within and across environments. Stability analysis for seed yield was calculated to know the response to genotype × environment interactions. The mean squares due to G×E (linear) were significant depicting genetic differences among genotypes for linear response to varying environments. Mean squares due to pooled deviations were highly significant, reflecting considerable differences among genotypes for non-linear response. The genotypes were found common in majority of characters namely, CSOFSC12-2, CSOFSC11-5, ANDO1, OS344, OS1, SKO105, CSAOFSC14-6, JHO03-91 and JHO851. Considering all the characters and all the models of stability under study none of the test genotypes were found stable for all the traits however, six genotypes namely,CSOFSC12-2, CSOFSC11-5, CSOFSC11-4, ANDO1,JHO03-91 OS344, OS1 SKO105, CSAOFSC14-6,JHO2007-1 and JHO851 were found stable for maximum characters under all dates of sowing in present study. These genotypes would be useful for commercial exploitation or can be exploited as elite gene pool in future breeding programme.

Fifty diverse genotypes of barely (Hordeum vulgare L.) were grown in the two environments with three replications during Rabi 2016-17 at Barley Research Area of Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar (India). The objective of investigation was to study the genetic variability for ten metric traits i.e. days to heading, days to maturity, plant height (cm), spike length (cm), number of tillers per meter row, number of grains per spike, 1000 grain weight (g), grain yield (kg/plot), biological yield (kg/plot) and harvest index (%). Genotypes significantly differed for all the traits under both the environments indicating enough variability in the experimental material. The mean performance of genotypes under timely sown for most all characters was higher than under late sown condition. The results under investigation also revealed wide range for all the traits under both the environments. Among all the traits under both the conditions, number of grains per spike had highest phenotypic and genotypic coefficient of variation followed by grain yield per plot. Moderate to high heritability in broad sense observed under timely sown for all the traits except of plant height, harvest index and number of tillers per meter which exhibited low heritability. However, under late sown conditions, all the traits showed moderate to high heritability except plant height. Highest genetic advance as per cent of mean was recorded for number of grains per spike followed by grain yield under both environments. Moderate to high heritability coupled with high genetic advance under timely sown was observed for number of grains per spike, grain yield, 1000-grain weight, biological yield and spike length likewise, for number of grains per spike, grain yield, number of tiller per meter, biological yield and 1000 grain weight under late sown indicating the importance of these traits in selection and crop improvement.

The present investigation was conducted on 49 different sorghum genotypes grown in randomized block design during kharif 2018 to evaluate, categorize and classify them on the basis of various DUS parameters. A total of 11 different qualitative traits were characterized as per the guidelines for the conduct of test for Distinctiveness, Uniformity and Stability on sorghum by PPV & FRA, GOI. The observations were taken on five randomly selected plants of each genotype for the following characters viz., anthocyanin coloration of coleoptiles and leaf sheath, midrib colour of leaf and flag leaf, colour of dry anther and glume, panicle shape and density, awn-ness, grain luster and colour. Results revealed that out of 49 genotypes, 11 genotypes were grouped under yellow green and remaining 38 under greyed purple on the basis of anthocyanin colouration of coleoptile. On leaf sheath anthocyanin coloration basis, 15 genotypes were greyed purple and 34 were yellow green. Thirty two genotypes had greyed yellow and 17 genotypes had white leaf mid rib colour. Mid rib coloration of flag leaf in 21 genotypes was white and in 38 genotypes it was found to be yellow green. Presence of awn was observed in 14 genotypes. On the basis of anther colour of dry anther, 17, 1, 8 and 23 genotypes were categorized into four groups viz., yellow orange, orange, orange red and greyed orange, respectively. Whereas, glume colour in genotypes were classified into five categories viz., green white (10), yellow white (13), greyed yellow (7), greyed orange (13) and greyed purple (6). Five different categories of panicle density viz., very loose (3), loose (11), semi loose (16), semi compact (18) and compact (1) were observed at maturity in these sorghum genotypes.

An experiment was conducted in 26 genotypes of sweet corn to study Principal Component Analysis at Department of Millets, Centre for Plant Breeding and Genetics, Tamil Nadu Agricultural University, Coimbatore during kharif, 2014. Eight quantitative and five qualitative characters were taken under observation to estimate substantial variation and relationship among sweet corn genotypes to identify the best performing lines. Analysis of variation for such quantitative traits in diverse line showed considerable and dissimilar level of variability. Green cob yield was highly significant and positively correlated with green cob length (0.410), green cob girth (0.579) and number of kernel rows per cob (0.421) however total sugar, sucrose and starch was non-significant negatively correlated with green cob yield. Principal component analysis showed the amount of variation by principal components as 1 to 6. Clustering analysis based on various morphological traits assorted 26 sweet corn genotypes into eight clusters. Dendrogram based on hierarchal clustering grouped genotypes based on their morphological traits rather than geographic origin. The diverse genotypes will be used for future breeding programme.

Forage Res 2020, 45(4), 258-63.
The present investigation was carried out to study per se performance and magnitude of heterosis in sorghum [Sorghum bicolor (L.) Moench]. The 27 hybrids were generated by L × T fashion during early summer, 2018 at Sorghum Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa using three females (2219A, 296A and 7A) as a line and nine males (DS 105, DS 173, DS 155, DS 137, DS 167, DS 176, DS 149, DS 156 and DS 161) as a tester. The resultant 27 hybrids along with 12 parents and two standard checks (GJ 39 and CSH 30) were evaluated in randomized block design with three replications at Sorghum Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa during kharif, 2018. Perusal of per se performance of parents and their hybrids for different traits evinced that 296A among the females, DS 155 among the males and 7A × DS 156, 296A × DS 173 and 296A × DS 161 among the hybrids exhibited higher mean performance for green fodder yield per plant and some of the yield contributing traits. For earliness, female 2219A, male DS 173 and hybrid 2219A × DS 137 were found superior as they exhibited lower values for days to flowering. Looking to the grain yield per plant, 7A among the females, DS 155 among the males and 296A × DS 137 among the hybrids recorded more grain yield per plant. Significant heterosis over better parent and best standard check (GJ 39 and CSH 30) was observed in many hybrids for various traits. The hybrid 296A × DS 173 manifested significant and positive heterosis over better parent (82.20 %), standard check GJ 39 (52.45 %) and CSH 30 (13.45 %), while hybrids 7A × DS 173, 2219A × DS 155 and 296A × DS 137 evinced significant and positive heterosis over better parent and standard check GJ 39 for the green fodder yield while in case of grain yield, the hybrid 296A × DS 137, 7A × DS 161 and 7A × DS 149 exhibited significant and desirable heterosis over better parent (92.21, 3.95 and 31.05 %), standard check GJ 39 (30.84, 27.83 and 19.78 %) and CSH 30 (14.02 and 11.40 %), respectively.

Fifteen kodo millet genotypes were grouped into six clusters using Tocher’s method. Among the clusters, cluster I and II had four genotypes each, three genotypes in cluster III, two genotypes in cluster IV, cluster V and VI were solitary each containing single genotype. Maximum intra cluster distance was recorded for cluster III (187.36) followed by cluster II (151.48) and cluster IV (147.29), which suggested that genotypes in cluster III were relatively more diverse among themselves. Genotypes falling in V and VI exhibited higher inter cluster distances (2066.95), followed by cluster V and III (1553.74) and cluster VI and II (1536.57) indicating that genetic makeup of genotypes falling in these clusters may be entirely different from one another. Intermating of the genotypes in cluster III (TNAU 86, TNPSU 301 and PPK 1) with genotypes in cluster IV (GAK 3 and RPS 694), cluster V (KMNDL 1) and cluster VI (BK 14-48) would produce superior genotypes for the respective traits.
