dc.description.abstract A field experiment was conducted with 41 populations of Brassica napus at the experimental field of Sher-e-Bangla Agricultural University, Dhaka to study the variability and interrelationship among the advanced populations during November 2018 to March 2019. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Analysis of variance for each trait showed significance differences among the populations. The first two components with Eigen value were greater than others. The utmost inter cluster distance was observed between cluster I and V and the maximum intra-cluster distance was found in cluster I. Phenotypic variances were higher than the genotypic variances for all the characters studied. Days to 50% flowering (90.45) exhibited the highest value of heritability and number of seeds per siliqua (47.71) exhibited the lowest value of heritability. The significant positive correlation with seed yield per plant was found in days to 1 flowering, days to 50% flowering, number of primary branches per plant, number of secondary branches per plant and number of siliqua per plant. Path co-efficient analysis revealed that days to 1 st flowering, days to 50% flowering, plant height, number of secondary branches per plant, number of siliqua per plant and thousandseed weight had the positive direct effect on yield per plant. Considering group distance and other performance populations G 1 (Nap-2037), G 2 (Nap-10020), G (Nap-10015), G 4 (Nap-10019), G 9 (Nap-084), G 13 (Nap-10009), G (Nap-179), G 32 (Nap-0885), G 34 (BARI-8) and G 37 30 (Nap-205) might be suggested for future hybridization program. en_US
