STABILITY BERAVIOUR OF SOME SOYBEAN [GLYCINE MAX (L.) MERILL) GENOTYPES UNDER ENVIRONMENTAL VARIABILITY

Abstract

Stability behaviour of twenty one germplasm collection of soybean was studied for yield and scpne of the yield attributes under five different environments. Significant genotype X environment interactions were observed fot almost all the characters. For characters like l()()..seed weight and yield per plant, only linear component contributed significantly towards GE interaction variance. For rest of the characters both linear and nonlinear components contributed towards GEinteraction variance. Genotypes Moti, PK-308, PK-472, BO-l, BO-12, Bragg and PK-73-203 showed average stability for seed yield. Whereas 05-16-1-37-1 had above average stability.
