Abstract:
A research was conducted in the experimental farm of Sher-e-Bangla Agricultural university, by
using twenty populations of Brassica rapa obtained through different inter-varietal crosses and
grown in Randomized Complete Block Design with three replications at the experimental field of
Sher-e-Bangla Agricultural University (SAU), Dhaka during December 2020 to February
2021.The purpose of the experiment is to study the variability, heritability, genetic advance,
correlation and direct and indirect effect of different characters on seed yield. The characters
visualized significant variations among the genotypes. Phenotypic variance was higher than the
genotypic variance for every character. Minimum difference between phenotypic and genotypic
variance was seen in number of primary branches per plant (σ
