Abstract: A trial was conducted to assess variability and correlation for seed yield and its attributes with a set of 64 genotypes of castor (Ricinus communis L.). The characters studied were 12 quantitative characters viz., days to 50% flowering of main raceme, days to maturity of main raceme, number of nodes up to main raceme, plant height up to main raceme, total length of main raceme, effective length of main raceme, number of capsules on main raceme, number of effective branches per plant, seed yield per plant, 100-seed weight, oil content and shelling out turn. The analysis of variance revealed highly significant differences among the mean square due to genotypes for all characters. High GCV and PCV, high heritability coupled with high genetic advance as per cent of mean was observed for all the characters except number of nodes up to main raceme and number of effective branches per plant. Seed yield per plant had significant and positive correlation with total length of main raceme, effective length of main raceme, number of capsules on main raceme and oil content.
