Abstract

Thirty-six linseed genotypes were tested to assess the genetic variability, among studied genotypes using randomized block design (RBD) at department of genetics and plant breeding, AU Kota in 2019-20. Substantial amount of genetic variations were observed with low influence of environment indicated consistence performance of the genotypes. Analysis of variance exhibit that there were statistically significant differences among all the genotypes using in the investigation for most of the traits. A wide range of variability was observed for yield and yield components viz., Days to 50% flowering, Days to maturity, Plant height (cm), Number of primary branches per plant, Number of capsules per plant, Number of seeds per capsule, 1000-Seed weight (g), Harvest Index (%), Protein content (%), Oil content (%), Seed yield per Plant (g). GCV and PCV were highest for number of capsules per plant followed by number of primary branches per plant. Greater magnitude of heritability coupled with high to moderate genetic advance as per cent of mean was observed for number of capsules per plant, number of primary branches per plant, plant height, seed yield per plant and 1000-seed weight

Conclusion

From the above study, the analysis of variance for various traits in the investigation revealed statistically significant differences among all the genotypes, indicating substantial genetic variability. A wide range of variability was particularly observed in important yield and yield-related traits such as Days to 50% flowering, Days to maturity, Plant height, Number of primary branches per plant, Number of capsules per plant, Number of seeds per capsule, 1000 Seed weight, Harvest Index, Protein content, Oil content, and Seed yield per Plant
