Abstract:
The experiment was conducted using Randomized Complete Block Design (RBD) in three replications and the trail was totally consisted thirty six genotypes. The experimental materials were obtained from IIPR Kanpur. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the character studied. GCV and PCV were highest for number of capsules per plant followed by number of primary branches per plant. Heritability was high for all the character except number of seeds per capsule, protein content and seed yield per plant. Greater magnitude of heritability coupled with high to moderate genetic advance as percent 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. Seed yield per plant had positive and significant correlation with plant height, number of capsules per plant 1000 seed weight and protein content, while highly correlate with number of capsules per plant. Path coefficient analysis revealed that number of capsules per plant has strong positive direct effect on seed yield per plant. Based upon genetic variability, heritability, genetic advance as percent of mean, correlation and path coefficient analysis, it was concluded that number of capsules per plant, number of primary branches per plant, 1000 seed weight and plant height are most important yield components in linseed breeding programme.
