Abstract:

The present study was carried out for development of hybrids in sponge gourd for earliness and yield traits. Twenty eight crosses were developed by crossing 8 × 8 diallel mating design (excluding reciprocal). Evaluated the crosses and along with their parents in randomized block design (RBD). Analysis of variance indicated highly significant differences for growth, earliness and yields characters, which suggesting presence of wide genetic variability. The magnitude of standard heterosis was found in desirable direction for early and yield traits viz., days to first pistillate flower appearance in the cross IC-284795 x Patna Loca (-23.07), for 50% flowering in the cross IC-284795 x Patna Local (-18.89%), sex ratio in the cross IC-336759 x Patna Local (-53.41%), for number of fruit per vine in the cross IC-284795 x Patna Local (34.56%), average fruit weight in the cross IC-336759 x Patna Local (110.09%). Such crosses could be exploited for practical plant breeding programme in sponge gourd.
