Abstract:

Cotton is one of the most important fiber and cash crop of India and plays a dominant role in the industrial and agricultural economy of the country. Sixty crosses with thirteen parents and three checks viz., PKV-Hy-4, NHH-206 and NHH- 44 were grown in Randomized Block Design with two replications. The results showed that the tester AKH-07R possessed the highest GCA effect for the seed cotton yield per hectare and also exhibited high GCA (in desirable direction) for the traits, number of sympodia, number of bolls per, harvest index and cotton seed yield per plant. The line CAK 23 B reported the high GCA effect to the traits, earliness index, number of bolls per plant, boll weight, seed cotton yield per plant, seed cotton yield per hectare, ginning percentage and fiber strength. The CMS cross, CAK 53A x AKH-07 R possessed the highest SCA for the traits number of sympodia per plant, number of bolls per plant, boll weight, seed cotton yield per plant also it showed highest per se performance for the seed cotton yield per plant. From the conventional system the highest SCA effect for the trait seed cotton yield per plant observed for crosses CAK 23B x DHY-286-1R with high mean performance. For the fiber traits in CMS, highest SCA for strength showed by SRT-1A x R-2000-23 also high SCA for the traits upper half mean length. In the conventional hybrids, CAK 53B x R-2000-23 exhibited the highest SCA effect for the fiber strength also the high per se performance to the seed cotton yield.
