ABSTRACT
Morphological and yield related traits of 23 genotypes were studied to ascertain the genetic and phenotypic correlation and contribution of these traits towards the yield directly and indirectly in linseed. The genotypic and phenotypic correlation coefficients obtained between different traits was similar in direction, while in magnitude, genotypic correlation higher than the corresponding phenotypic correlations. The results indicated that seed yield had significant positive correlation with plant height (rg= 0.492*; rp= 0.455**), number of capsules per plant (rg= 0.915**; rp= 0.877**) number of branches per plant (rg= 0.450*; rp= 0.449*) and days to physiological maturity (rg= 0.729**; rp= 0.578**) showed positively and significantly correlated with seed yield per plant both at phenotypic and genotypic levels. Path coefficient analysis revealed that direct and indirect effects of genotypic path coefficients were higher in magnitude than the corresponding phenotypic path coefficients. Number of capsules per plant showed the higher and positive direct effect on seed yield.
