Abstract:
The experiment was carried out using 32 genotypes for various variability parameters, correlation analysis, path analysis for ten quantitative characters in castor. The high heritability along with high genetic advance was found for yield per plot, branches per plant, capsules per primary spike, primary spike length, plant height, 100 seed weight and nodes per plant. Yield per plot was found highly significant and positively correlated with days to 50% flowering, primary spike length, capsules per primary spike and 100 seed weight. Path analysis revealed the highest positive direct effect of capsules per primary spike on yield per plot, followed by oil content, 100 seed weight, plant height and days to maturity. The maximum intra cluster distance observed in cluster II (D = 8.99) followed by cluster I (D = 8.24), suggesting that crosses should be attempted between the genotypes belonging to clusters separated by large inter cluster distance.
