Combining Ability Analysis and Heterotic Effects for Cotton Fiber Quality Traits

Combining ability and gene action can help breeders to select suitable parents and appropriate breeding strategy. In the present study combining ability analysis and heterotic effects for cotton fiber quality traits were studied in a set of diallel crosses involving six cotton genotypes. The aim of this study was to estimate general combining ability of parents, special combining ability of F1 diallel crosses, heterotic effects of F1 diallel crosses in in the breeding programme to develop high quality cotton varieties. Randomized complete block design was used to test 15 F1 diallel crosses, and 6 parents. Analysis revealed significant general combining ability effects for all the investigated traits and additive gene effects were important in the inheritance of the traits. Analysis also revealed significant SCA effects for only fiber fineness and spinning consistency index traits and additive and non-additive gene effects were important in the inheritance of the traits. General combining ability was found significant for all investigated traits, revealing the important role of additive gene effects. Specific combining ability was found significant for the Mic and SCI, revealing that non-additive gene effects, as dominant or epistatic are important, but not for Len, Str and SFI.
