Abstract

Adaptability of wheat genotypes while considering their random effects had been studied by recent analytic measures. High yield and better adaptability of VL892, VL3010 & HS627 wheat genotypes identified during 2015-16. HPW433 had specific adapta¬tions to Kalimpong, Shimla and Dhaulakuan whereas HS626 for Imphal and Bajura, while HS625 identified for Malan in biplot analysis exploiting 80.6 % of total GxE interaction sum of squares. BLUE based measures identified VL892, VL3010 & HS627 for high yield and better adaptability. Biplot analysis based on 78.9 % reflected HPW433 and HS626 had specific adapta¬tions to Bajura, Imphal, Dhaulakuan locations. Second year (2017-18) expressed better adaptability along high yield of HS490, HS660 and VL 3017 wheat genotypes. Genotypes VL3018, VL3016 and VL892 had exhibited specific adapta¬tions to locations of Una, Almora and Dhaulakuan. Adaptability measures as per BLUE exhibited better adaptability and high yield of HS490, HS660 and VL 3017 whe
