Heritability and genetic advance for seed yield and its attributes in sesame (Sesamum indicum L.)

The present investigation was accomplished in summer 2023 at Department of Seed Technology, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The experimental material consisted of six families, each having six generations (P1, P2, F1, F2, BC1 and BC2) were evaluated in Compact Family Block Design with three replications during summer, 2023 at Department of Seed Technology, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The observations were recorded for twelve different characters The high heritability coupled with high genetic advance was observed in cross I for plant height; cross III for number of branche per plant; cross IV for number of branche per plant, seed yield per plant, oil content and oleic acid content. While low heritability coupled with low genetic advance observed in cross II for 1000 seed weight and linoleic acid content; cross III for days to maturity, number of seed per capsule and oil content; cross IV for plant height and capsule length; cross V for days to flowering, number of capsule per plant, number of seed per capsule, 1000 seed weight, seed yield per plant, oleic acid content and linoleic acid content; cross VI for plant height and oil content. The presence of high heritability coupled with high genetic advance, moderate heritability with high genetic advance or low heritability with high genetic advance, indicate that the role of additive gene action. So, selection may be effective in these crosses.
