ABSTRACT
In the present study total 40 genotypes (11 parental genotypes, 28 F1 hybrids and one commercial check- Abhinav) were evaluated during 2014 to 2015 in order to estimate the extent of heterosis and quality traits like, TSS, lycopene content, ascorbic acid content (vitamin-C), average pulp content, pulp: skin ratio, solid: acid ratio and titrable acidity. In which, significant differences among genotypes were obtained for all the traits. In the present investigation, mid parent heterosis ranged from -45.31 to 182.20 %, better parent ranged from -53.23 to 127.18 % and standard heterosis -0.79 to 295.83 % for fruit yield. The maximum standard heterosis recorded by cross JTL-12-12× JT-3 was 295.83 %, followed by NTL-1 × AT-3 (273.39 %), JTL-12-12 × GT-2 (196.52 %), JTL-12-12 × AT-3 (177.53 %), NTL-1 × JT-3 (160.31 %), JTL-12-10 × GT-2 (156.80 %) and JTL-12-11 × GT-2 (155.55 %). Positive significant heterosis was found for all the traits.
Key words: Heterosis, Tomato, Quality parameters, Processing, Hybrids.
