The present study was carried out during the Rabi season of 2022–2023 at the Research Farm of Dholi Kothi farm, Tirhut College of Agriculture, Dholi, Muzaffarpur, under RPCAU, Pusa, Samastipur, Bihar. Twenty-five linseed genotypes, including two checks i.e. Kota Alsi-6 (local) and T-397 (national)were evaluated in a Randomized Block Design with three replications to assess genetic variability, correlation, path coefficient analysis, heritability and genetic advance for yield and seed quality traits. Significant genetic variability was observed for all traits studied. Seed yield and related attributes exhibited the highest genotypic and phenotypic coefficients of variation, with PCV consistently exceeding GCV, indicating environmental influence. High heritability coupled with high to moderate genetic advance as percentage of mean were recorded for seed yield, seed yield per plant, seedling root length, number of capsules per plant, number of primary branches per plant and plant height, suggesting predominance of additive gene action and effectiveness of direct selection. Traits such as days to maturity showed high heritability but low genetic advance, implying non-additive gene effects and the need for alternative breeding strategies. The findings provide valuable guidance for prioritizing traits in linseed breeding programmes aimed at enhancing productivity and seed quality under irrigated conditions.
