Abstract:

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. The level of heterosis was acceptable for seed-cotton yield and fiber traits. Combining-ability analysis across environments showed significant (P < 0.01) effects for genotypes, GCA, SCA, genotype × environment, GCA × environment, and SCA × environment interactions. Combining-ability variance revealed predominance of non-additive gene effects for seed cotton yield, ginning outturn, fibre parameters, earliness parameters, additive gene effects for plant height, seed index, lint index and equal contribution of additive and non-additive gene effects for sympodial branches and boll weight. A positive relationship was found between GCA effects and mean performance of parents, heterobeltiosis and SCA whereas negative relationship was observed between heterobeltiosis and better parent mean as the environmental quality increased.
