In the present study 55 hybrids were developed by crossing 11 parents in half diallel fashion. 55 hybrids along with 11 parents and 2 checks were evaluated for yield and yield related components and screened against tomato leaf curl virus disease during summer 2022. Significant differences among genotypes were obtained for all the traits. Positive and negative high significant heterosis was found for many of the traits over the mid parent and commercial checks respectively. The highest number of fruits per plant in parent and hybrid was reported in AVTO-1424 (33.30) and AVTO-1424 × DMT-2 (41.80) respectively. The results revealed that the hybrid AVTO-1429 × DMT-3 exhibited significant positive standard heterosis for fruit yield per plant over both checks, and showed resistant to ToLCV. Out of 55 hybrids, 37, 13, 2 and 3 hybrids were exhibited resistant, moderate resistant, tolerance and susceptible reaction to tomato leaf curl virus. AVTO-1429 × DMT-3, was found to be significantly superior with respect to yield and yield contributing traits.
