Abstract:
Bitter gourd is unique and versatile vegetable among the cucurbits due to its nutritional value. For the development of effective heterosis breeding programme in bitter gourd one need to elucidate the genetic nature of quantitatively inherited traits and estimated prepotency of parents in hybrid combinations. In the present investigation, GCA/SCA ratio was less than unity for all the studied traits. The results indicated the predominance of non-additive gene action. Gy 3-1-1-1-2, IC-505621 and Preethi were identified as good general combiners for yield and its related traits and can be used in future for developing superior new heterotic combinations. The cross combinations IC-470550 × Preethi, IC-66023 × Pusa Aushadhi and Gy 3-1-1-1-2 × Phule Green Gold exhibited superior sca effects and identified as top specific combiners for yield and its related traits. So these combinations can be used for development of hybrids for commercialization.
