Analysis of combining ability in experimental hybrids of Sweet corn (Zea mays var. saccharata)
Main Article Content
Abstract
The GCA and SCA variance in combining ability analysis among the crosses involving 11 sweet corn inbreds was significant for all the traits studied. The additive and nonadditive gene effects were found predominant for all the traits. Inbred lines IPSA-8761, IPSA-8761, IPSA-8752, IPSA- 8757 and IPSA-8754 were identified as good general combiners for different traits. Specific crosses namely, IPSA-8753 x IPSA-8755, IPSA-8753 x IPSA-8761, IPSA-8754 x IPSA-8758 and IPSA-8756 x IPSA-8758 had significant SCA effects and were identified for various flowering and maturity traits whereas IPSA-8755X IPSA-8758 and IPSA- 8754X IPSA-8757 showed significant SCA effect for ear weight with husk, without husk and sugar content. The hybrid IPSA-8753 x IPSA-8759 also showed significant SCA effect for the main sweet corn traits referring to green ear weight without husk and sugar content. These findings could serve as crucial inputs required for improvement of sweet corn.
