Abstract:
A field experiment with 120 tomato hybrids generated from sixteen tomato lines using a half-diallel mating design was conducted over two seasons. We assessed these tomato hybrids for their suitability in processing. We considered 22 yield and processing traits for assessing the suitability of hybrids for processing. Among the hybrids, the maximum TSS (5.32 °Brix) was found in IIHR-2957 x CLN3916D. The experiment revealed that the hybrid IIHR-2833 x IIHR-2955 (2.17) and IIHR-2784 x IIHR-2833 (2.20) had a minimum locule number. The hybrids IIHR-2784 x IIHR-2955 (32.50) and IIHR-2955 x Arka Ashish (39.24) had minimum number of seeds per fruit. The hybrids IIHR-2327-1 x Arka Ashish (101.83) had maximum number of fruits per plant and IIHR-2327-1 X IIHR-2955 (8.18 kg) had high yield per plant. The maximum shelf life to the extent of 44.5 days was shown by IIHR-2847 x IIHR-Sel.19. IIHR-Sel.57 X CLN3916D (14.5%) had high dry matter content and Arka Ashish x CLN3916C (9223 mPa) had high viscosity. Overall, we identified as many as 11 hybrids for most of the processing traits studied. These promising hybrids can be used for developing tomato lines suitable for processing which can be used in hybridization programs.
