Generation mean analysis revealed the presence of epistasis and higher magnitude of dominance effects than that of additive effects for both the traits in all the crosses except 'PBC 830' x 'Pb Lal' for fruit weight. Hence, it can be concluded that fruit weight and fruits/plant in chilli are controlled by both additive and non-additive gene effects but additive effects has more influence on their inheritance, so selection can be used for improving these traits.
