“…Despite the considerable knowledge accumulated over the last 20 years about the genetic architecture of VOCs and phenolics, breeders still need insight into the improvement they can expect in HF1 varieties given the right parental combinations for these traits. To date, most of the efforts towards the characterization of the impact of heterosis and cross direction have been directed on yield-related traits [ 37 , 38 ] and quality traits [ 26 , 27 , 28 , 39 ] in tomato. The most exhaustive study addressing the evolution of metabolite content in HF1 compared to parental lines has been carried out on 28 primary metabolites among which amino acids, organic acids and sugars [ 29 ].…”

Flavour and nutritional quality are important goals for tomato breeders. This study aimed to shed light upon transgressive behaviors for fruit metabolic content. We studied the metabolic contents of 44 volatile organic compounds (VOCs), 18 polyphenolics, together with transcriptome profiles in a factorial design comprising six parental lines and their 14 F1 hybrids (HF1) among which were five pairs of reciprocal HF1. After cluster analyses of the metabolome dataset and co-expression network construction of the transcriptome dataset, we characterized the mode of inheritance of each component. Both overall and per-cross mode of inheritance analyses revealed as many additive and non-additive modes of inheritance with few reciprocal effects. Up to 66% of metabolites displayed transgressions in a HF1 relative to parental values. Analysis of the modes of inheritance of metabolites revealed that: (i) transgressions were mostly of a single type whichever the cross and poorly correlated to the genetic distance between parental lines; (ii) modes of inheritance were scarcely consistent between the 14 crosses but metabolites belonging to the same cluster displayed similar modes of inheritance for a given cross. Integrating metabolome, transcriptome and modes of inheritance analyses suggested a few candidate genes that may drive important changes in fruit VOC contents.

“…Most of the hybrids outperformed their best parent and best commercial hybrid for all the traits, suggesting the high potential of the newly developed hybrids to compete with commercial varieties for off-season production in hot dry regions. The existence of heterosis has been reported for several agronomic traits (fruit weight, fruit setting percentage, yield, plant height) in tomatoes (Basté et al, 2010;Krieger et al, 2010;Shalaby, 2013;Solieman et al, 2013) and metabolites and fruit quality traits (Basté et al, 2010;Fortuny et al, 2021;Shalaby, 2013) under optimal temperature growing conditions and heat stress (Bhattarai et al, 2016;Scott et al, 1986). Previous studies reported maximum mid-parent heterosis values of 37.75% (Emami et al, 2018), 104.39% (Liu et al, 2021), and 108% (Liu et al, 2021) for yield under optimal conditions and 84.79% under heat stress (Bhattarai et al, 2016).…”

This present study was undertaken to (i) assess the performance of hybrids under heat stress, (ii) determine the combining abilities of parental lines and their crosses, and (iii) identify the most efficient heterotic grouping method to classify the lines. We evaluated two sets of hybrids generated using the NC II design and a partial diallel mating design. Most crosses outperformed their parents and the best commercial hybrids for fruit weight per plant (FWP), fruit set (FS), fruit weight (FW), and the number of fruits per plant (NFP) under heat stress. The specific (SCA) and the general (GCA) combining ability variances were significantly higher than zero. The crosses Fla.7171 × P005 and CLN2026D × ATS020 had positive SCA effects and high per se performance for FW and FWP. BJ01 was the best combiner for FWP, NFP, and FS. The SNP‐based heterotic grouping was 28% more efficient than the heterotic grouping based on the GCA of multiple traits method and classified the lines into three groups. These findings provide a foundation for speeding up heat‐tolerant hybrid in tomatoes.
