Abstract: The present investigation was undertaken with a view to study the magnitude of variation and association for seed yield and to identify promising genotypes. The experimental material comprising of 30 linseed genotypes were evaluated in randomized block design with three replications during rabi 2018-19 and the data were recorded on thirteen morphometric traits. Sufficient genetic variability was observed for all the characters. High PCV and GCV was observed for aerial biomass, primary branches per plant, capsules per plant, and seed yield per plant. For rest of the traits PCV and GCV was moderate to low. High heritability with high genetic advance was observed for aerial biomass, capsules per plant, primary branches per plant, seed yield per plant, secondary branches per plant, technical height and harvest index. Seed yield per plant showed positive and significant correlation with length of flowering period, seeds per capsule, harvest index, primary branches, secondary branches, capsules per plant, aerial biomass and 1000-seed weight while, plant height and technical height showed negative correlation. On the basis of path coefficient analysis, capsules per plant followed by 1000-seed weight exhibited the highest direct effects on seed yield per plant.
