STABILITY ANALYSIS FOR YIELD AND SOME QUALITY TRAITS IN WHEAT (TRITICUM AESTIVUM L.)

Published on

Stability analysis of S4 advanced generation lines along with six checks of wheat was made
for six characters including three quality traits. The G x Einteraction, environment (linear)
and environment (nonlinear) components were highly significant for all the traits. Twenty
nine genotypes showed stable response for tryptophan content and 12 for seed hardness.
Many genotypes also showed stability for protein content. Grain yield was positively
correlated with 1000-grain weightand harvest index but negativelyassociated with protein,
tryptophan content, and seed hardness. Protein content showed positive association with
tryptophan cOntent and seed hardness. ,
