Abstract:
Nature of gene action involved in the inheritance of important quantitative and qualitative traits is elucidated by using eight parents in a diallel method without reciprocal to obtain information for selection of the parents and crosses with favorable GCA and SCA effects. The analysis of variance revealed the significant differences among the parents and crosses for all the 14 characters studied. All the characters were exhibited higher magnitude of SCA variances than GCA variances which revealed that non-additive gene action was played an important role in the inheritance of these trait except for pedicel length, fruit weight and 1000 seed weight, where additive gene was responsible for the expression of the trait. According to GCA effects, the genotypes UHF CHI 7, UHF CHI 5, UHF CHI 14 and UHF CHI 15 found to be promising general combiners for yield and yield components. The SCA effects revealed that eleven crosses viz., H6, H17, H7, H10, H8, H26, H3, H25, H14, H1 and H9 were identified as promising hybrids for fruit yield and its yield component characters.
