Environmental impact on the stability of gene action for seed cotton yield in cotton (Gossypium hirsutum L.)

Hybrids are widely accepted in all crops to improve yield, but genotype × environment interaction plays an important role in achieving high yield and superior quality traits. Six lines and seven testers of Gossypium hirsutum L. varying in seed cotton yield and fiber traits were assessed for hybrid vigor using a line × tester system across three different locations. The objective of this study was to detect influence of genotype x environment interaction on stability of gene action.
