Genetic Variability Studies in Yellow Seeded Linseed

The experimental materials consisted of 40 yellow seeded genotypes of linseed taken from “AICRP on linseed, Department of Genetics and Plant Breeding, IGKV, Raipur”, Chhattisgarh, India along with one check variety Surabhi. Seed yield is an important trait and the cumulative result of a number of component traits controlled by polygenes and influenced greatly by the environmental factors. Hence, yield alone would not be effective for selection of superior genotypes. In order to make the selection effective one has to give emphasis on the yield attributing traits. According to analysis of variance, “significant differences exist for all the parameters investigated from yellow seeded linseed genotypes.” It demonstrates that the yellow seeded genotypes of linseed have sufficient variability in seed yield and contributing characteristics. 1000 Seed weight (7.7g) and seed yield (15g) were the highest in the YLS-31 and YLS-23 genotypes, respectively. The highest GCV was found in number of secondary branches per plant (39.5%) followed by seed yield (32.1%), harvest index (21.6%), and number of primary branches per plant (24.3%). The highest PCV was found in the number of primary branches per plant (47%). Number of secondary branches per plant (43.2%), 1000 seed weight (37.9%), number of capsules per plant (33.9%) and harvest index (22.8%) were the next most important factor.
