Abstract

The gene effects for four quantitative characters were studied in ten crosses of sesame. The additive component was significant and present in sizable proportions for the characters studied. Dominance was higher in magnitude than additivity. Epistatic effects were negligible for first capsule bearing node while dominance x dominance effect was in higher magnitude for capsules per plant and additive x additive effect was predominant for capsule bearing nodes to total nodes per plant. For volume of the capsule, additive x additive and additive x dominance interactions were observed. To exploit all these genetic effects characters associated with capsules can be improved through the use of recurrent selection to ultimately improve seed yield in sesame.
