Evaluation of the Performance of Parental Lines and Their F1 Hybrids for Yield and Attributing Traits in Tomato (Solanum lycopersicum L.)

The present investigation was carried out to obtain information based on per se performances of parents and their combinations for genetic improvement in tomatoes. Ten promising genotypes were crossed in a dial manner (excluding reciprocals). Half diallel set of 45 F1’s in tomato was evaluated in Randomized Complete Block Design (RBD) with three replications for eighteen yield and yield attributing traits during Rabi 2020-21 (Y1) and 2021-22 (Y2) at the Main Experimental Station (MES), Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) India. The study evidently showed highly significant differences being observed for most of the traits under study. Based on per se performance, parent P3 (3.27 kg) exhibited the highest yield per plant followed by P6 (3.20 kg). The per se performance of crosses i.e. P3XP4 (3.33kg), followed by P2 x P9 (2.17 kg) produced significantly higher yield per plant than the general mean and P2 X P3 (24.97), followed by P1 X P2 (26.18) was found to be early as observed from character of days to 50% flowering. These hybrids may be exploited as a new variety after selection and subjected to multi-locational trials for their release for cultivation on a commercial scale.
