Abstract:

The present investigations were carried out to estimate the genetic components of variation for yield and its contributing traits in sponge gourd. Genetic components D^, H^1 and H^2 were significant for days to first male flower anthesis, node number of first male flower, days to first female flower anthesis, node number of first female flower, fruit length, fruit weight, number of fruits per plant, main vine length and total yield except D^ in case of number of primary branches which indicate the importance of both additive and dominant gene effects in regulating these traits. However, higher value of H^1 and H^2 compared to D^ for all the traits showed that non-additive gene effect have a greater role than additive gene effects. Significance value of h^2 for days to first male flower anthesis, days to first female flower anthesis, fruit weight, number of fruits per plant, number of primary branches and total yield. The average degree of dominance (H^1/D^) and ratio of KD/KR were more than unity for all the traits showed preponderance of dominant genes in the expression and hence, suggested that hybrid breeding can be used efficiently to improve yield and its contributing traits in sponge gourd.
