Abstract: A trial was conducted with 19 diverse genotypes of linseed under rainfed condition at research farm of TCA, Dholi, Muzaffarpur during rabi season of 2021-22 in order to detect genotypic variability, heritability and genetic advance for yield and yield attributing traits. Analysis of variance exhibited significant variability among all the genotypes for different traits under studied. Estimates of mean performance revealed that the entry SLS 139 had significant superiority over the best check i.e. T 397 in respect of days to flowering, days to maturity, oil content and germination percentage. The estimate of genetic parameter showed moderate to high GCV and PCV for traits like no. of Capsules per plant, Seed yield (kg./ha.) and oil content. Further analysis revealed high heritability for days to flowering, days to maturity and oil content while high heritability coupled with high genetic advance as percentage of mean were observed for the trait oil content. Selection of these traits may be more rewarding for improvement of drought tolerant genotypes in linseed under changed climatic conditions.
