ADAPTABILITY PERFORMANCE OF FEED BARLEY GENOTYPES EVALUATED UNDER NWPZ OF THE COUNTRY

Highly significant effects of the environment (E), genotypes (G), and GxE interaction had been observed by AMMI analysis. Environment explained 63.4% whereas GxE interaction accounted for 23.4% of treatment variations in yield during first year. Harmonic Mean of Genotypic Values (HMGV) expressed higher values for PL906, KB1707, UPB1080 genotypes. Ranking of genotype as per IPCA-1 were NDB1723, NDB1709, HUB266. While IPCA-2, selected BH1023, BH1024, NDB1723 genotypes. Values of Measures ASV1 selected NDB1723, NDB1709, HUB266 and ASV identified NDB1723, NDB1709, BH1023 barley genotypes. Adaptability measures Harmonic Mean of Relative Performance of Genotypic Values (HMPRVG) pointed towards PL906, KB1707, UPB1080 and Relative Performance of Genotypic Values (RPGV) identified KB1707, PL906, RD2994 as the genotypes of performance among the locations. Biplot graphical analysis observed clustering of adaptability measures PRVG, HMPRVG, along with GM, HM in a group. During 2019-20 cropping season Environment effects accounted 61.4% whereas GxE interaction contributed for 26.9% of treatment variations in yield. HMGV expressed higher values for DWRB137, PL906. IPCA-1 scores, desired ranking of genotypes was UPB1080, PL906. While IPCA-2 pointed towards PL906, RD2994, as genotypes of choice. Analytic measures ASV and ASV1 selected PL906, UPB1080 barley genotypes. HMRPGV selected DWRB137, PL906 whereas PRVG settled for DWRB137, KB1707. Biplot analysis seen cluster of ASV, ASV1 IPC1, Mean, GM, HM along with adaptability measures PRVG, HMPRVG observed in adjacent quadrant.
