Abstract

In present study, diallel cross analysis was carried out for development of hybrid in bottle gourd [Lagenaria siceraria (Mol.) Standl]. The gene effects with respect to its nature and magnitude for yield and quality attributes (10 characters) were studied by involving 66 hybrids obtained by crossing 12 × 12 half diallel pattern during Kharif 2013 and Zaid 2014. Additive as well as dominant component of variance were significant of most of the characters. The estimates of dominance component ($1 and $2) were higher than those of additive () component for all the characters and suggesting major role of dominance component in controlling the expression of character. Average degree of dominance showed over dominance for all characters in both the seasons. The ratio of dominance and recessive alleles suggested that the dominant alleles were distributed frequently than the recessive for all the characters.
