The present experiment is undertaken to estimate the genetic variability in a set of 14 linseed genotypes. From ANOVA table it evidenced that significant variation for all the traits under study suggested existence of sufficient variability among themselves. PCV estimates were higher than GCV for all the character where as GCV estimates were higher than PCV for branch numbers and capsules numbers. For the traits, days to 50% flowering and days to maturity showed higher heritability due to major contribution of genotypic portion. Combined high heritability with high genetic advance was noticed for capsule number, branch number indicating these traits were under control of additive gene action. If selections were exercised based on phenotype would be effective for improvement of these traits

GCV, PCV, ANOVA.

Dominance genetic variance with the predominance of additive type of gene action was noticed for seed yield, number of branches and number of capsules per plant. Hybridization and selections as per pedigree method would be beneficial for genetic improvement of these traits.
