“…The thickness of pericarp is a desirable trait as it imparts fruit firmness which may be suitable for canning, better storage and long distance transportation (Gonzalez, 1985 andKalloo, 1988) [12,16] . Thicker pericarp results in minimizing postharvest losses, thus maintaining the quality and improved shelf life (Kumar et al, 2019) [19] . Pericarp thickness exhibited variation among treatments which ranged from [21] ; Sharma and Thakur, (2008) [28] ; Sekhar et al (2010) [26] ; Soleiman et al (2013) [33] ; Dagade et al (2015) [11] ; and Kumar and Paliwal, (2016) [17] in tomato.…”

“…Heterosis has also been reported for traits related to quality of fruit, such as total soluble solids, pericarp thickness and content of ascorbic acid (TIWARI and LAL, 2004). Also, in tomato, heterosis has been reported by many researchers namely SHARMA et al (2006); MONDAL et al (2009); GARG et al (2013); CHAUHAN et al (2014); KAUSHIK et al (2015); TAMTA and SINGH (2018); KUMAR et al (2019). Heterosis is a reliable tool for enhancing yield, from 30% to 400% (SOLIEMAN et al 2013).…”

The current study in tomato (Solanum lycopersicum L.) was conducted at PAU, Ludhiana with the objective of developing hybrids possessing combined resistance to late blight and leaf curl virus diseases along with desirable horticultural characteristics. The experimental material which included 32 F1 hybrids (developed by line ? tester method), 12 parental lines (8 lines and 4 testers; including susceptible check Punjab Chhuhara) and standard check NS-524 were all planted in randomized complete block design with three replications. The values of ?2SCA/?2GCA were more than unity for all the traits except average fruit weight and ascorbic acid content, indicating the predominance of non-additive gene effects. Cross combinations CLN-154 ? LBR-12 and CLN-154 ? LBR-21 recorded significant heterosis over better parent and check for fruit yield and other quality characteristics. Artificial and natural screening was performed for all the experimental material against late blight and leaf curl virus diseases respectively. Out of 32 hybrids, crosses namely CLN-154? LBR-12, CLN-154 ? LBR-21, PVB-1 ? LBR-10, PVB-4 ? LBR-12 and CLN-104 ? LBR-10 were identified for combined disease resistance against late blight and leaf curl virus, in relation to desirable horticultural characteristics particularly fruit yield, average fruit weight, pericarp thickness, dry matter, titrable acidity and ascorbic acid content with fair amount of heterosis. Hence, the hybrids which displayed good potential in yield with acceptable performance of qualitative traits, along with combined disease resistance could be utilized for commercial exploitation.

“…In fact, heterosis can be observed in F1 generation in respect to one or more traits, as well as in respect to single morphological, physiological, or biochemical traits [81]. Heterosis manifests differently in the individual F1 combinations, depending on the value of the cultivars or parental lines, and their general combining ability (GCA) and specific combining ability (SCA) [80,82]. However, heterosis effects cannot be exactly predicted beforehand, but sometimes the probability of predicting it could be very high, even more than 90% [81].…”

Tomato (Solanum lycopersicum) is the globally most consumed vegetable. The objective of this research was to analyze physico-chemical, nutritional and sensorial components (taste and flavor) in two new commercial hybrids (AS 300 F1 and AS 400 F1) and their four F7 parental lines. Two widely grown F1 hybrids (Precos F1 and Addalyn F1) were used as controls. The results obtained for carbohydrates (HPLC-RID) indicated that the highest values (27.82 mg/g) were recorded in the paternal line AS 10 of the new hybrid AS 400 F1. The highest values of total organic acids (HPLC-VWD) were recorded in Addalyn F1 (5.06 m/g), while the highest value of phenolic compounds (HPLC-DAD-ESI⁺) were identified in the maternal line AS 09 of the hybrid AS 400 F1 (96.3 µg/g). Intrinsic sensory values were analyzed by male and female tasters of different ages using a hedonic scale. The tasters’ perception revealed obvious taste differences between tomato genotypes. The study allowed determining genetic parameters of interest (heterosis and heterobeltosis) for the new hybrids, as well as a detailed characterization of the chemical composition and organoleptic quality of the parental breeding lines and their hybrids, which is useful in tomato breeding.
