The F1 indicate non-additive genetic variance for all the characters, eight characters exhibited over dominance recessive alleles were predominant for branches/ plant and capsules/ plant. The distribution of genes with positive and negative effects were symmetrical to nearly symmetrical for 1000 seed weight, days to maturity, branches/ plant, capsules on main stem, capsules/ plant and yield/ plant. https://www.biotech-asia.org/vol2no2/gene-action-for-yield-and-its-components-in-sesame-sesamum-indicum-l/ Gene action; yield; Sesamum indicum
