ABSTRACT:

The study of gene action for yield and components in 6x6 hald diallel cross. 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.
