Twenty eight F 1 hybrids involving 8 distinct genotypes (parents) in half diallel fashion were evaluated to study the gene action of yield and its contributing characters in pumpkin (Cucurbita moschata Duch ex. Poir). Dominant gene action was observed for all the characters, viz., vine length, fruit maturity, fruits per plant, fruit weight and yield per plant. In all these characters, dominance (H 1) component of variance was greater than additive (D) component of variance. The heritability in narrow sense was found to be less than 0.50 for majority of characters. Low narrow sense of heritability coupled with higher degree of non-additive gene action (dominance variance) in yield and its components suggested that heterosis breeding might be advantageous for obtaining higher gains in pumpkin.
