Combining ability effects were estimated for yield, yield components in a 8 × 8 diallel analysis excluding reciprocals. The variances for general combining ability (GCA) and specific combining ability (SCA) were highly significant indicating the presence of additive as well as non-additive gene effects in the traits studied. The relative magnitude of these variances indicated that additive gene effects were more prominent for all the characters. The tomato genotype Hawaii 7998 (P3)proved to be the best general combiner for yield and its component traits followed by 12-1 (P5) and BWR-5 (P6).Cross combinations viz., Palam Pride × BWR-5 (P4 × P6), 12-1 × BWR-5 (P5 × P6), Palam Pride × 12-1 (P4 × P5), Hawaii 7998 × 12-1 (P3 × P5) and CLN 2123 A-1 red × Arka Abha (P2 × P8) were the best five specific combinations for marketable yield per plant in pooled environment under organic farming conditions. | Organic tomatoes: Combining ability for fruit yield and component traits in tomato (Solanum lycopersicum L.) under mid himalayan region
