During the spring-summer seasons of 2019 and 2020 (April-September), fourteen different genotypes of hybrid tomato were evaluated under poly-house at the Vegetable Research Farm, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur to estimate genetic variability among horticultural traits and to evaluate these hybrids for protected cultivation. Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the biggest hazards to tomato agriculture areas after its pest outbreak. Sequencing and characterization of the internal transcribed spacer (ITS) region 12S primers were used to identify all pest up to species level. To explore the tomato germplasms T. absoluta infestation, two field trials were established on April 1st and September 21st, 2019-2020. 14 genotypes, including check verities, were assessed using similar approaches. Leaf damage, on the other hand, increased over time and peaked at 100% in 10–11 weeks after transplanting in all genotypes. Within 11 weeks following transplanting, the greatest leaflet damage recorded ranged from 64.18 percent to 100 percent, with a marketable fruit yield of 7.62–7.97 (m2/kg) in both experiments. In the current study, 14 tomato cultivars were evaluated for bacterial wilt disease resistance.
