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
