Abstract:

The present study was carried out on heterosis for fruit yield and yield related traits in sponge gourd. Fifteen hybrids of sponge gourd were developed using six parents in half diallel fashion were studied for estimation of heterosis for 10 yield contributing traits. Hybrids PSG-82 × PSG-07-04, PSG-07-04 × PSG-161 and PSG-07-04 × PSG-199 were found most promising for earliness and yield. These hybrids exhibited heterosis to the tune of 59.36, 48.45 and 43.85 per cent over their better parents and 81.58, 69.16 and 63.91per cent, respectively over the check cultivar for fruit yield per hectare. The cross combination PSG-82 × PSG-07-04 recorded highest significant heterobeltiosis for yield and its contributing traits and it was identified for evaluation in multi-location trial and commercial exploitation.
