A combining ability analysis was carried out to assess the nature of gene action governing yield and its component traits in muskmelon using a half diallel mating design. The experimental material consisted of six parents and fifteen hybrids evaluated during late kharif 2021 and early summer 2022. The hybrids were evaluated in a Randomized Block Design with two replications to study their performance for various growth, earliness, and yield parameters. Analysis of variance revealed significant differences among parents and hybrids for most of the traits studied, indicating the presence of substantial genetic variability. The estimates of general combining ability (GCA) and specific combining ability (SCA) variances showed that non-additive gene action was predominant for the majority of traits, as evidenced by lower σ²GCA/σ²SCA ratios. Among the parental lines, VRMM-310 exhibited significant positive GCA effects for yield and its contributing traits and were identified as good general combiners. Several cross combinations, notably VRMM-310×VRMM-37 , recorded high and significant SCA effects along with superior mean performance for yield, suggesting their potential for hybrid development. The results indicated that both additive and non-additive gene actions played an important role in the inheritance of yield and related traits, and the identified parents and crosses could be effectively utilized in future breeding programmes aimed at yield improvement in muskmelon.
