Fifty eight genotypes of linseed (Linum usitatissimum L.) were evaluated two consecutive years for variability and other genetic parameters based on various traits. Substantial amount of genetic variations were observed with low influence of environment indicated consistence performance of the genotypes. High heritability, GCV, PCV and GA was observed for number of branches/plant, number of capsules/plant, days to 50% flowering and capsule weight/plant. Oil content showed high heritability with low genetic advance indicating non-additive genetic behavior. Positive and significant correlations were observed among days to 50% flowering, plant height, number of branches/plant. Seed weight had significant and positive correlation with number of capsules/plant, capsules weight/plant, husk weight/plant and test weight. The branches/plant, number of capsules/plant, and plant height identified as important traits for selection in linseed breeding program.
