Stability for wheat genotypes had been compared in Central Zone of the country as per the BLUP and BLUE of yield values. Measures based on ranks of BLUP for 2015-16 i.e. Si s identified G1, G5, G7, G6. Corrected yield measures CSi s pointed towards G1, G2, G5, G6. Values of NPi (s) identified G1, G2, G7. Overall similarity among non-parametric measures tested by Kendall’s coefficient of concordance. Positive correlations of Si s , CSi s & NPi (s) observed with other measures. Biplot analysis exhibited cluster of CV with CCV, Si 1 , Si 2 , Si 4 , Si 5 , Si 7 , Si 3 , Si 6 , NPi (2), NPi (3) & NPi (4). Based on BLUE’s of genotypes, Si s found G1, G7, G4, G5 while CSi s identified G5, G4, G2 as opposed to G7, G1, G4 genotypes as by values NPi (s). Positive and negative correlations exhibited by Si s , CSi s & NPi (s) with the measures. Biplot analysis observed large cluster comprised of Yield with GAI, NPi (2), NPi (3), NPi (4), Si 1 , Si 2 , Si 4 Si 3 , Si 5 , Si 6 measures. Second year of study (2017-18) as per BLUP’s seen, Si s settled for G8, G7, G2 genotypes. While NPi (s) settled for G1, G2, G8, G5. Negative correlations of yield had been observed with MR, CV, Med, NPi (2), NPi (3), NPi (4) while positive with GAI, CMR, CSi 6 . Measure CV expressed affinity with NPi (2), NPi (3) & NPi (4), SD, Si 3 , Si 6 , Si 1 , Si 2 , Si 4 , Si 5 , Si 7 in Biplot analysis.. Measures Si s as per BLUE’s pointed towards G2, G5,G8, G7 whereas CSi s settled for G6, G8, G7. . Wheat genotypes G8, G2, G7, G5 favoured by least values of NPi (s). Positive correlation Si s , CSi s & NPi (s) with others. Large cluster of CCV, CSD, NPi (1), Si 1 , Si 2 , Si 4 , CSi 1 , CSi 2 , CSi 3 , CSi 4 , CSi 5 , CSi 6 , CSi 7 and Z1 measures.
