Studies were undertaken to investigate the nature and magnitude of gene effects operative in the inheritance of fruit number and fruit weight. The generation mean analysis showed that basic additive dominance model was inadequate to explain variation and suggested the presence of nonallelic interactions like digenic, trigenic or linkage in the inheritance of fruit number and fruit weight. Duplicate type of epistasis was observed in most of the crosses. The analysis of second degree statistics indicated the presence of epistasis. The additive component was higher than dominance. The degree of dominance suggested partial dominance for these two traits.
