Abstract:

A study was carried out at Department of Horticulture, Agricultural College and Research Institute, Madurai during 2015-2016. Sixteen F1 crosses of ridge gourd obtained through a Line × Tester crosses involving eight parents were evaluated to study heterosis for growth, and yield parameters. Maximum standard heterosis for vine length L3 x T2 (8.67%),for internodal length in L2 x T3 (-20.72%), for node to first female flower appearance in L4 x T3 (-15.03%), for days to first female flower appearance in L3 x T2 (-23.68%), for sex ratio in L1 x T1 (13.13%), for number of seeds per fruits in L4 x T4 (16.97%), for average fruit weight in L2 x T3(22.48%), for fruit length in L3 x T1 (23.63%), for fruit diameter in L4 x T1 (13.56%), for fruit yield per vine in L3 x T1 (24.74%). The three best performing F1 hybrids viz., the cross L3 x T1 (24.74%) followed by L4 x T1 (19.24%) exhibited the highest standard heterosis for total yield per vine.
