Combining ability analysis is a cornerstone of crop improvement programs, enabling breeders to identify genetically superior parents and promising hybrid combinations. The present study investigates the general and specific combining abilities (GCA and SCA) of six lines and four testers in Indian mustard (Brassica juncea L.) across 19 agro-morphological traits using a line × tester mating design. Analysis of variance (ANOVA) revealed highly significant variation among genotypes, indicating ample genetic diversity for effective selection. GCA effects identified NRCDR-02 and Ashirwad as consistent general combiners for key traits such as plant height, branching, oil content, and biological yield. SCA effects highlighted cross combinations like GLS-10 × Rohini, GLS-35 × Ashirwad, and GLS-56 × Ashirwad as superior specific combiners, particularly for seed yield and structural traits. The results underscore the importance of both additive and non-additive genetic effects in trait expression. These findings offer valuable insights for breeding programs aiming to develop high-yielding mustard hybrids with improved plant architecture and oil potential.
