Abstract

During the summer of 2017, a diallel set of seven parents and their 21 F1s were evaluated at the experimental field of Vegetable & Floriculture, Bihar Agricultural University, Sabour, Bihar to assess the combining ability and degree of heterosis for fruit yield and its component traits. The importance of both additive and non-additive genetic components for these traits was confirmed by combining ability analysis, which demonstrated that both general and specific combining ability differences were important for all of the characters. The per se performance was found to be a good indicator of the parents' GCA effects and the crosses' SCA impacts. Pusa Aushadhi and Konkon Tara were found as the best general combiners for yield and its components features among the parents assessed. The superior specific cross combinations Konkan Tara × Gangajali Small, Konkan Tara and Pirpaiti local, and Thailong × Gangajali Small seemed suitable for further use in bitter gourd breeding. The findings a
