Abstract: The experimental materials consisted of 65 entries comprising 48 hybrids, 4 female lines and 12 testers along with one standard check (Arka Rakshak) were evaluated in a Randomized Complete Block Design with three replications under three environments during kharif-rabi season of the year 2016-17 at the Main Vegetables Research Station, Anand Agricultural University, Anand to estimate the combining ability effects and gene action for fruit yield, yield components and fruit quality traits in tomato. The source of variation due to lines × testers was significant for all the characters reflected importance of non-additive gene action in the inheritance of most of the characters. The parents DVRT 2, H 24, TBK 00113 and ATL 11-05 displayed high gca effect for fruit yield per plant and some desirable traits like number of fruits per plant and fruit weight. These parents possessed high concentration of favourable genes for more number of traits and would be utilized in multiple crossing programmes. Out of 48 hybrids studied, 22 exhibited significant positive sca effects for fruit yield per plant on pooled basis. The top five hybrids on the basis of significant positive sca effects for fruit yield per plant were H 24 × DARL 66, H 24 × SL 120, AT 3 × VTG 93, AT 3 × Feb 4 and DVRT 2 × NTL 14-71. Combining ability analysis provides specific information on selection of better parents and cross combinations for their further use in hybrid breeding programme.
