The present experimental research was carried out during Rabi season of 2022-2023, consisting of forty genotypes, including checks, and it was conducted with three replications in Randomized Block Design (RBD). Highly significant differences were found among Indian mustard genotypes for all characters studied. GCV and PCV were highest for biological yield, seed yield per plant, test weight and siliquae on main raceme. The combination of heritability and genetic advance was high for all the characters except siliqua length and siliqua per plant. A greater magnitude of heritability coupled with high genetic advance as percentage of mean was observed for oil content, biological yield, test weight, and seed yield per plant, revealed that simple selection can be led to fast genetic improvement of the mustard genotypes under the study. Seed yield per plant showed significant positive genotypic correlation with siliqua on main raceme length, number of biological yields, seeds per siliqua and primary branches per plant.
