“…In addition, β-carotene content has also exhibited a significant positive association with lipophilic antioxidant capacity (r = 0.86; p < 0.001), having strong antioxidant potential [ 30 ]. Thus, the enhancement of carotenoids contents in tomato using LEDs during post-harvest storage, especially lycopene, is of great interest in the marketing of tomato, which looks for the development of high pigment varieties containing natural antioxidants by the use of different tools, such as breeding programmes [ 31 ].…”

Different strategies have been developed to increase the concentration of bioactive compounds in tomatoes during post-harvest, with ultraviolet light (UV) and light emitting diodes (LEDs) being interesting tools. The aim of this study was to evaluate the effect of ultraviolet (UVA at 366 nm and UVC at 254 nm) pre-treatment (1 kJ/m2) and red–blue LED light (25.4 µmol/m2/s) on the concentration of carotenoids, (poly)phenols and hydrophilic/lipophilic antioxidant capacity during 7 days of refrigeration storage of green tomatoes (Solanum lycopersicum L.) cultivar “Raf”. In addition, special attention was paid to quality parameters (weight loss, colour, acidity, soluble solids and ripening index). Tomatoes exposed to LED light at 6 °C for 7 days increased up to three times the total carotenoids content (mainly β-carotene and E-lycopene) compared to tomatoes refrigerated in the dark, while UV treatments alone did not significantly affect the carotenoid content. Besides, exposure to LEDs increased the hydrophilic and lipophilic antioxidant capacity of tomatoes by 30%, without affecting phenolic contents. Thus, LED treatments alone during refrigerated storage fostered ripening and improved the nutritional value of tomatoes, without compromising quality parameters. Further studies must be carried out to evaluate the impact on sensory attributes and consumer acceptance.

“…These can be considerably high in the accumulation of both sugars and acids. The importance of the interactions has been emphasized in tomato regarding the accumulation of functional compounds, especially vitamin C (Leiva-Brondo et al, 2012), and to a lower extent carotenoids (Leiva-Brondo et al, 2016). This differential behavior may lead to overestimating or underestimating the value of an accession and consequently emphasizes the need to perform screening studies in multienvironmental designs.…”

The genetic potential of accessions from Solanum section Lycopersicon (S. lycopersicum L., S. lycopersicum var. cerasiforme, S pimpinellifolium L., and S. habrochaites Knaap & Spooner) for breeding tomato taste has been studied in three environments with clonal replicates. The environment clearly affected the accumulation and level of variation of sugars and acids and derived variables through a direct effect. It seems that photosynthetically active radiation would exert a major effect on sugar accumulation while in the case of organic acids the effect of temperature might be more important. Even more, important genotype × environment interactions can considerably modify the real value of germplasm, being considerably higher in wild species. The environment affected not only mean contents but also the levels of variation. Thus, the need to develop multienvironmental screening programs is suggested to identify solid sources of variation. An important intraaccession variability was also found in wild germplasm, emphasizing the need to analyze a high number of plants per accession in order to identify sources of variation. Accessions with a significant genotypic contribution to the accumulation of sucrose within the Lycopersicon group were identified and may be interesting to analyze the regulation of vacuolar invertase. Accessions with different genotypic contributions to citric, malic, and glutamic acid accumulation have also been identified. These accessions will be valuable for the development of breeding programs considering the acid component of taste. Additionally, these genetic resources will be interesting to study the regulation of the tricarboxylic acid cycle and the gamma-aminobutyric acid shunt.

“…In vegetable crops, pre-breeding has been successfully employed for developing health beneficial glucosinolates (3-methylsulphinylpropyl or 4methylsulphinylbutyl) rich genetic stocks in broccoli by marker assisted introgression of QTL1 and QTL2 from Brassica villosa (Sarikamis et al 2006). Leiva-Brondo et al (2016) identified, accessions BGV6195 of Solanum pimpinellifolium, LA1423 of S.

Vegetable crops are rich in dietary micronutrients (minerals, vitamins), antioxidents and functional phytochemicals ‘nutraceuticals’. However, some of the elements are of public health concern such as β-carotene, iron, calcium and folic acid which attracts breeders’ interest to improve their content in food sources including vegetable crops so that their dietary intake could be increased and their deficiency problems reduced. Some nutraceutical compounds such as anthocyanin, β-carotene, lycopene and glucosinolates have been reported to play active role in health and their contents have been found more in beet root, cauliflower, carrot and broccoli, respectively. The attempts through conventional breeding methods have been slow and inadequate, hence new developments in molecular and biochemical diagnostics tools and techniques showed promise in improving the nutraceutical contents and other quality traits. Molecular markers, next generation sequencing, RNA interference (RNAi) and genetic engineering have great promise in reducing time and cost involved in quality breeding. The present review summarise attempts and potential of improving the nutraceuticals and quality traits in vegetable crops. Key words:.
