An investigation was carried out to study the performance of 18 hybrids of pumpkin (Cucurbita moschata Duch. ex Poir) through Line x Tester mating design. Observations were recorded on the traits viz., vine length, days to first female flower appearance, node number for first female flower appearance, sex ratio, days to first harvest, fruit number per vine, fruit weight, flesh thickness and fruit yield per vine, besides quality traits such as ascorbic acid content, beta carotene content and crude fibre content in the fruit. Evaluation of hybrids for per se and sca revealed that the cross Rajasthan Local x Pusa Viswas (L5 x T2) was adjudged as the best hybrid, since it recorded the highest mean and sca effect for traits of study viz., fruit weight and total yield per vine. The next best hybrid, Ambili x Pusa Viswas (L2 x T2) could also be justified as the best combination through less days for first female flower appearance, more fruit number per vine, crude fibre content and fruit yield per vine. The next best hybrid, Saras x Pusa Viswas (L3 x T2) could also be adjusted as the best combination, since it recorded the highest mean and sca effect of traits of study like flesh thickness and beta carotene content. Thus, first generation hybrids can be well-utilized for exploiting hybrid vigour to achieve improved quality.
