Abstract: The present study of genetic variability was carried out using 30 genotypes of linseed for 10 quantitative characters. The results showed significant differences and wide range of variability for all the characters. The seed yield per plant was recorded highest values for phenotypic and genotypic coefficients of variation followed by number of capsules per plant. The high heritability coupled with high genetic advance as percent of mean was observed for seed yield per plant, test weight, capsules per plant, plant height, branches per plant, days to first flowering and days to 50% flowering indicated the predominance of additive gene action in the expression of these traits and can be improved through individual plant selection.
