Abstract: Field experiments were takenup to evaluate eleven parents, thirty crosses and three commercial checks of tomato (Solanum lycopersicum L.) for stability studies involving yield and processing traits. Results from the investigation revealed significant differences among the genotypes for all the traits evaluated. Pooled analysis of variance indicated significant differences among genotypes and environments and the interaction component, genotype × environment was also significant for the traits studied. The hybrids as a whole exhibited higher mean values with regression coefficients around unity, indicating greater production and stability. The present study emphasized that crosses viz., EC-620360 × Pusa Ruby and EC-608415 × Arka Saurabh, EC-608415 × Arka Abha, EC-608415 × Punjab Chhuhara and EC-619982 × EC-620557 with significant mean and bi<1 possess above average stability and are adapted to unfavourable environments. These hybrids are to be further evaluated under different locations to confirm their stability for commercial hybrid development.
