Variability occuring in 40cultivars of brown sarson was made with respect to yield and certain to its com -ponents.Both phenotypic and genotypic coefficients of variation were maximum in seed yield/plant while they were minimum in days to following.Broad sense heritability was highest in siliqua length.Genetic advance in per cent was the highest in seeds yield/plant.Both heritability and genetic advance were low in seeds/siliqua.Seed yield/plant:howed high phenotypic and genotypic correlations with primary branches/- plant and 100-seeds weight.melative officiency of selection index based on seed yield /plant.plant height and 100 seed weight was the highest and was found better than th one calcilated on all the four characers.
