Abstract
Linseed (Linum usitatissimum L.) is a self-pollinated (2n = 30) annual Rabi season crop mainly cultivated for flax fiber and oil due to its commercial use. The present investigation was carried out to study an association analysis among the yield and yield attributes using 75 linseed genotypes including 10 checks in a randomized block design with three replications at Oilseeds Research Farm, Kalyanpur, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, (India) during Rabi season of 2019-20. The correlation analysis revealed that the traits number of secondary branches per plant followed the number of primary branches per plant and number of capsules per plant at both the genotypic and phenotypic levels. The results of the path coefficient analysis revealed that traits such as the number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, and plant height exhibited a strong and positive direct effect on seed yield per plant at both the genotypic and phenotypic levels. The seed yield can be improved by selecting traits such as number of primary branches per plant, number of secondary branches, number of capsules per plant, and plant height. It is recommended that the breeder focus on these traits in linseed to enhance its commercial value for the farming community.
