AMMI analysis for feed barley genotypes evaluated North Wes tern Plains Zone of India had expressed highly significant
effects of environments (E), GxE interaction and genotypes (G). Interaction effects GxE accounted for 23.4 and 26.9%,
while environment explained up to tune of 63.4 and 61.4%; during cropping seasons of 2018-19 and 2019-20, respectively.
ASTAB measure achieved the desirable lower values for PL906, DWRB137, UPB1080. Composite measure MASV1
found PL906, DWRB137, RD2552, and as per MASV ranks desired PL906, DWRB137, and UPB1080 genotypes
would be of choice for these locations of the zone. Superiority index while weighting 0.65 and 0.35 for average yield
& s tability found KB1707, PL906, RD2994 as of s table performance with high yield. Biplot graphical analysis as per
73.7% of variation of the measures exhibited MASV1 clubbed with ASTAB, EV, SIPC, Za, W3, WAASB and MASV
measures. For the second-year lower value of WAASB measure had observed for KB1707, RD2994. Barley genotypes
DWRB137, PL906 were selected as per values of ASTAB measure. MASV1 selected PL906, DWRB137 while PL906,
DWRB137 identified by MASV as genotypes of choice. Superiority index pointed towards PL906, DWRB137 feed barley
genotypes. About 64.3% of variation among the measures under biplot analysis seen AMMI based IPCA1, Za, W1, W2,
W3, ASTAB, WAASB measures grouped in quadrant. Simultaneous utilization of AMMI and BLUP of genotypes would
be more appropriate to recommend high-yielding s table genotypes.
