Genetic Variability and Correlation Studies on Germplasm of Yellow Sarson [B. rapa (L.) var. yellow sarson] for Seed Yield and its Component Traits

Genetic variability and correlation in sixty three indigenously collected germplasm accessions of yellow sarson were evaluated for seed yield and its components traits. Analysis of variance for seed yield and its related components showed that there was significant variability among accessions. The maximum PCV was observed in seed yield per plant followed by seeds per siliqua. High heritability coupled with high genetic advance were observed for plant height, seeds per siliqua, 1000-seed weight, seed yield per plant and harvest index. The seed yield per plant was positively and significantly correlated with main shoot length, siliquae on main shoot, primary branches per plant, oil content, 1000-seed weight, harvest index and days to maturity. The accessions IC36l512, IC342762 and lIC334290 were identified as useful genotypes for various traits.
