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. |
