ABSTRACT
The present study was conducted at Agricultural Research Station, Kota (Rajasthan) during winter of 2010-11 to assess the genetic variability and nature of inter-relationships among traits affecting linseed seed yield. Sixteen linseed genotypes were grown in Randomized Block Design with three replications to evaluate ten quantitative and qualitative characters. The results indicated that the genotypes showed significant variability for all the traits studied. The phenotypic and genotypic coefficient of variability was relatively high for seed yield pe plant, number of capsules per plant and harvest index. However, the difference between GCV and PCV was less which indicated the little influence of environment on the expression of these characters. High heritability (broad sense) coupled with high genetic advance and genetic gain was observed for capsules per plant, seeds per capsules and harvest index. Further, genotypic correlation coefficient revealed the importance of above characters as they showed positive and significant correlation with seed yield.
