GENETIC VARIABILITY, CORRELATION AND PATH ANALYSIS STUDIES FOR YIELD AND YIELD COMPONENT TRAITS IN SESAMUM (Sesamum indicum L.)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 61
Abstract
Twenty six advanced varietal lines of sesame genotypes were grown during kharif 2015-16 at the Project Coordinating Unit Sesame and Niger, JNKVV, Jabalpur for the estimation of phenotypic and genotypic variances, heritability, genetic advances, correlation and path coefficient analysis for seed yield and yield related traits. High values for phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was recorded for seed yield per plant (g) followed by number of capsules per plant and hence improvement through selection could be possible. High heritability and genetic advance as per cent of mean were recorded for seed yield per plant followed by number of capsules per plant indicating that selection could be effective for improvement of these characters. Phenotypic and genotypic correlation analysis revealed strong positive association of seed yield per plant with number of secondary branches per plant and number of capsules per plant. Path coefficient analysis revealed high positive direct effect of number of secondary branches and number of capsules per plant on seed yield per plant. Hence number of secondary branches and number of capsules per plant may be good selection criteria for seed yield per plant.
