Abstract: Heterosis breeding can be used to achieve improvement in quantity, quality, and productivity of pumpkin (Cucurbita moschata Duch. ex Poir.). A Line x Tester mating design was used to study standard heterosis for small size, thick flesh, beta carotene, yield and yield-related characters in pumpkin during 2016-2017. Eighteen hybrids, developed by crossing six lines with three testers and a commercial check, 'Arjuna', were evaluated for small size, thick flesh, β carotene, yield and yield related characters and indicated presence of heterotic vigor. The hybrid 'Ambili' x 'Pusa Viswas' had highest negative standard heterosis for the fruit weight followed by ‘Saras x CO 2’. Heterosis for days to appearance of the first female flower, flesh thickness, crude fibre and fruit yield per vine was in the desired direction in 'Odisha Local' x 'Pusa Viswas'. Estimates of standard heterosis for fruit yield indicated that hybrid 'Rajasthan Local' x 'Pusa Viswas' had the highest positive value followed by hybrid 'Ambili' x 'Pusa Viswas'. These hybrids had high heterosis for most component traits and can be used for exploita¬tion of heterosis and released as promising hybrids after multi-location testing.
