An experiment was conducted to study the correlation and path coefficient analysis of 11 quantitative traits during rabi 2017-18 at Zonal Agricultural Research Station Morena, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, Madhya Pradesh, India comprised 27 genotypes of Indian mustard including 9 parental genotypes and 18 specific F1 crosses. Analysis of variance on 11 quantitative traits was worked out which exhibited considerable amount of genetic variability in genotypes for all the traits. The mean, range, genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), habitability in broad sense and genetic advance were calculated. High GCV and genetic advance coupled with high heritability for number of primary and secondary branches/plant, number of siliquae/plant, test weight and seed yield indicated the effectiveness of selection for these traits. Seed yield had positively associated with plant height, days to 50% flowering, days to maturity, oil content and test weight at both genotypic and phenotypic level indicating that these traits would help in improving the seed yield. Path analysis revealed that days to 50% flowering showed maximum positive direct effect, followed by oil content, days to maturity and test weight at both genotypic and phenotypic levels.
