Abstract:
The purpose of the current research was to evaluate the general combining ability impacts of parents and the specific combining ability effects of hybrids for yield and yield-related features, as well as to investigate their utility in hybrid creation. The 45 single cross hybrids developed through line x tester (L × T) breeding method together with parents (15 L and 3 T) were examined for grain yield and its attributing in three different environments during kharif and rabi season 2017-18. Results from the investigation revealed that the estimates of GCA effect for grain yield per plant showed that inbred line L₁₄ (24.04) exhibited maximum significant positive GCA on pooled basis and among the testers, T₃ was considered as good general combiner for various morphological traits. The estimates of SCA effect among hybrid revealed that maximum significant SCA in positive direction for grain yield/plant were exhibited by hybrid L₂×T₃ (37.51) on the pooled basis.
