Seed yield improvement via selection for capsule numbers in early segregating generations of sesame (Sesamum indicum L.) hybrids [electronic resource].

Includes references.

The breeding materials used in this study were 89 selected lines of sesame derived from crossing between 5 diverse parental genotypes. These lines were produced tbrough selection for higher number of capsules per plant that practiced among the F₂ segregating plants and within F₃ lines. The 89 selected lines along with their parents (as checks) were evaluated for seed yield and yield contributing traits in the F₃ and F₄ generations. The objectives were to estimate means, variances, phenotypic and genotypic correlations, heritability and predicted direct and correlated response to selection for seed yield and its main components as well as to determine the actual response of selection for higher capsules/plant on seed yield improvement in both segregating generations. Results showed highly significant differences among the F₃ and F₄ lines for all characters studied. Mean performance of the F₃ and F₄ lines, as groups, was higher than that of the check parents for fruiting zone length capsules/plant and seed yield/plant.
