Evaluating the Polyphenol Profile in Three Segregating Grape (Vitis viniferaL.) Populations

Abstract

This paper explores the characteristics of the anthocyanin and flavonol composition and content in grapes from plants resulting from intraspecific crosses of Vitis vinifera varieties Monastrell × Cabernet Sauvignon, Monastrell × Syrah, and Monastrell × Barbera, in order to acquire information for future breeding programs. The anthocyanin and flavonol compositions of twenty-seven hybrids bearing red grapes and 15 hybrids bearing white grapes from Monastrell × Syrah, 32 red and 6 white from Monastrell × Cabernet Sauvignon, and 13 red from Monastrell × Barbera have been studied. Among the intraspecific crosses, plants with grapes presenting very high concentrations of anthocyanins and flavonols were found, indicating a transgressive segregation for this character, and this could lead to highly colored wines with an increased benefits for human health. As regards the qualitative composition of anthocyanins and flavonols, the hydroxylation pattern of the hybrids that also may influence wine color hue and stability presented intermediate values to those of the parentals, indicating that values higher than that showed by the best parental in this respect will be difficult to obtain. The results presented here can be helpful to acquire information for future breeding efforts, aimed at improving fruit quality through the effects of flavonoids.

The composition of cell walls from grape skin in Vitis vinifera intraspecific hybrids

“…Therefore the CWM from this hybrid could be suggested as easily degradable, which could be related to better extractability. Interestingly, H80 hybrid showed high anthocyanin values accompanied by a high concentration of flavonols in a previous study . The study of CWM of the grape skin from hybrid plants provides relevant information for future breeding programmes in order to develop new cultivars adapted to a dry climate and with a cell wall composition improving extractability during the winemaking process, all without losing the originality of Monastrell wines produced in Murcia.…”

Analysis should be carried out to reinforce and deepen our hypothesis concerning the link with CWM composition and extractability of compounds of interest during winemaking, as well as to further determine which genes are involved in this genetic determinism of the skin cell wall composition.…”

“…It is essential to point out that results on the phenolic composition, profile and content in berries from similar intraspecific hybrids of Monastrell × Cabernet Sauvignon grapes have been previously published. 12,13 To the best of our knowledge, this is the first report on the effect of intraspecific crosses of V. vinifera cultivars Monastrell × Cabernet Sauvignon on the composition and structure of cell walls from grape skin of the F 1 population.…”

“…In the same way, the exocarp cells of skin samples from two representative hybrids as well as from parental grapes were visualized by transmission optical microscopy. It is essential to point out that results on the phenolic composition, profile and content in berries from similar intraspecific hybrids of Monastrell × Cabernet Sauvignon grapes have been previously published …”

Nutritional recommendations for individuals with Flammer syndrome

“…The polyphenolic content in red wine is higher than white wine [32], explaining why red wine exerts a stronger antioxidant capacity than white wines [33]. Polyphenols in wine lower the susceptibility of LDL lipids to oxidation [34] and improve endothelial dysfunction [35,36] impairment which leads to damage to vascular cells and the surrounding tissue.…”
