Abstract:
Tomato requires optimum temperature condition for proper growth and development which is directly proportional to yield traits. Day temperature should not exceed above 38°C otherwise fruit setting is failing due to flower dropping. Development of crops under polyhouse condition offers higher production and efficiency per unit area and better-quality items produced by providing favorable environment all year which acquiring importance. The present investigation was on twelve promising indeterminate tomato genotypes including check under polyhouse condition during spring-summer season, 2020-2021 to study the relative performance for yield and growth characters at Department of Vegetable Science of Agriculture, Khalsa College, Amritsar. The experiment was conducted in Factorial Randomized Block Design with three replications. The data revealed significant variation in twelve genotypes for various traits. Based on mean performance, the result conveyed that Heemsona and NS-4266 are good performing genotypes for yield and growth-related characters taken under study. Although, minimum days to 50% flowering, average fruit weight, shorter internodal length, higher fruit yield per plant and fruit yield kg per meter square were verified in EZ-9003, while KCA-2 was sophisticated for days to first picking whereas Punjab Sartaj was superior for number of fruits per plant and hybrid Yuvraj provides maximum plant height respectively. The significant findings are taken because of the interaction of genetic makeup of genotypes with the environmental conditions.
