Abstract: Twenty diverse cultivars of mustard in a Completely Randomized block design (CRBD) at AKS University, Satna, during Rabi season on November 2022. The twelve quantitative characters studied viz., days to 50% flowering, plant height (cm), primary branches per plant, secondary branches per plant, length of main raceme (cm), siliquae on main raceme, days to maturity, length of siliqua, seeds per siliqua, test seed weight (g), biological yield per plant (g) and seed yield per plant. Data were collected for twelve quantitative traits and estimated for variance, genetic variability, heritability and genetic advance. The design of the experiment indicated highly significant differences for all the characters due to treatments. The analysis of variance indicated the existence of sufficient amount of variability among genotypes for all the studied characters. PCV was higher than GCV for all the studied characters. The maximum GCV and PCV was observed for secondary branches per plant followed by seed yield /per plant, primary branches per plant, biological yield /plant, length of main raceme and siliquae on main raceme. High heritability (h2b) >80% were observed for all the studied characters except siliquae on main raceme and seeds per siliqua. High estimate of expected genetic advance at 5% were found for secondary branches per plant followed by seed yield per plant, biological yield per plant and primary branches per plant. High heritability coupled with high genetic advance indicated the predominance of additive gene action in the expression of these traits.
