Study on character association and contribution of yield related traits to seed yield in segregating generation (F4 Families) of Sesame (Sesamum indicum L.)
Keywords: Correlation coefficient, F4 families, Path coefficient analysis, Sesame.
AbstractOne hundred and twenty four F4 families of a cross E8 x Tamil Nadu Local were evaluated to study the
interrelationship between yield and yield attributing characters using correlation coefficients and contributions of
yield related traits to seed yield through path coefficient analysis. Days to 50% flowering, days to maturity, plant
height, number of branches per plant, number of capsules per plant, capsule length and number of seeds per capsule
had positive and significant association with seed yield per plant. The magnitude of correlation was highest in case
of number of capsules per plant (r=0.932) with seed yield per plant. Number of capsules per plant had highest
positive direct effect (0.9525) followed by equal contribution by number of seeds per capsule (0.1826) and 1000
seed weight (0.1821). Selection for capsules per plant shall improve seed yield in sesame.
