Abstract:
For the development of superior hybrids, estimates of general combining ability of parents and specific combining ability of the crosses help in proper selection of parents for hybridization. The high estimates of gca were exhibited by K-90, G
2 and Gyn
1 for most of the characters. In general, there was a close agreement between gca effects and per se performance but in certain cases, it did not hold good which may be due to higher degree of gene action involved. The superior cross combinations which recorded high sca estimates and per se performance for yield and number of fruits were K-90 x G
2 and K-90 x Gyn
1 and hence, may be exploited for the development of F
1 hybrid (s) after testing their performance at multi-locations for 2-3 years.
