The association and path coefficient analysis for yield and yield attributing traits in sesame (Sesamum indicum L.)

Abstract

This trial conducted on twenty seven elite lines were used for the studies of correlation and path coefficient analysis with twelve yield and attributing traits. The experiment was operated at Agriculture Farm, Nana JiDeshmukh New Agriculture Campus, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.). The field lay out was done in Randomized Block Design with 3 replications. Correlation coefficient for seed yield (kg/ha) revealed that highly significant and positive association with seed yield per plot and number of seeds per capsule. The direct effect on dependent variable (seed yield (kg/ha)) showed highly positive and significant by No. of seeds / capsule (0.661) followed by No. of capsules / plant (0.524), Oil content (0.181) and 1000 seed weight (0.117). The highest positive and direct effect on seed yield per plot at phenotypic level was recorded by No. of capsules per plant (0.148). therefore, selection of these characters would be effective for further breeding purpose of sesame.
