Abstract:
The present experiment was accomplished during Rabi 2020-21 consisting of forty genotypes of Indian mustard. The analysis of variance revealed highly significant differences among all the forty genotypes of Indian mustard for all the twelvequantitativecharacters under study. The estimates of PCV and GCV were found high for harvest index, moderate for 1000-seed weight, seed yield per plant and number of secondary branches per plant while, low for number of siliquae per plant, days to 50% flowering, number of seeds per siliqua, plant height, oil content and days to maturity. Very low differences in the magnitude of PCV and GCV were observed for the characters viz., days to maturity, days to 50% flowering and oil content indicated less influence of environment on these characters. High heritability coupled with high genetic advance as percent of mean was observed for harvest index, 1000-seed weight, number of secondary branches per plant and seed yield per plant. Harvest index, 1000-seed weight and number of siliquae per plant expressed highly significant and positive correlation with seed yield per plant at both genotypic and phenotypic level. Path coefficient analysis revealed the direct and positive influence of harvest index, number of siliquae per plant, 1000-seed weight and length of siliqua towards seed yield per plant.
