The present investigation was carried out to gather information on combining ability and magnitude of heterosis by following 'line × tester' mating design involving 11 lines and three diverse testers. Lines, testers their 33 cross combinations, along with standard check 'CH-1', were evaluated in a Randomized Complete Block Design with three replications during summer-rainy seasons of 2010 and 2011. Data were recorded on fresh fruit yield/plant along with component traits. Sufficient genetic variability was observed for all phenological, morphological, yield and yield contributing, and during both the years over the environments. Significant genotype × environment interactions for all the characters indicated a definite role of environment on the performance of genotypes/crosses. The line × tester analysis revealed significant differences due to lines, testers and line × tester interaction for majority of the traits pooled over environments indicating appreciable diversity in the experimental material. PAU Selection Long × Surajmukhi', 'LCA 436 × Pant C1', 'Chilli Sonal × Surajmukhi', 'Jawahar Mirch 283 × Anugraha' and 'Pusa Sadabahar × Surajmukhi' were the most promising crosses on the basis of SCA effects for yield and its related traits. A wide variation in magnitude and direction of heterosis was noticed for majority of the traits with maximum manifestation for fruits/plant, fresh fruit yield/plant. Hybrids 'Jawahar Mirch 283 × Anugraha', 'PAU Selection Long × Surajmukhi', 'Arka Lohit × Surajmukhi', 'LCA 436 × Pant C 1', 'LCA 436 × Anugraha' and 'LCA 443 × Surajmukhi' were the most promising crosses with significant heterobeltiosis and economic heterosis for yield and yield related traits.
