Since ancient times to present, grapes have been important to man, as they were considered to be healthy food due to their phytonutrients: polyphenol antioxidants, vitamins and minerals. The preliminary researches highlight the health-related benefits of red grapes, due to their antioxidant, antiseptic and anti-inflammatory properties. Starting from this information, compared researches have been conducted so as to highlight the evolution of some biological, technological and biochemical properties of three varieties of grapes for the red wines: Feteasca neagra, Pinot noir and Merlot, in two conventional and organic agricultural systems. The yield was analysed in both systems and the results showed some differences. Special attention has been attached to the polyphenol potential of the varieties. The polyphenols have a good potential to be introduced in human medicine as primary compounds of several medicines. The studies were carried out in 2017 at the French-Romanian Estates, where the organic agricultural system was applied, and the Research and Development Institute for Viticulture and Oenology Valea Calugareasca, which uses a conventional agricultural system.

Lately, there has been a special interest in scientific research in viticulture and winemaking regarding the content of different chemical compounds. These have been shown to have a positive impact on consumer health. Preliminary research highlights the benefits of red grapes on health through its antioxidant, antiseptic, antiinflammatory properties. The study was carried out on the Muscat of Hamburg variety during 2017 in two wine-growing areas: the Research and Development Institute for Viticulture and Wine Production Valea Călugărească where the conventional culture system was applied and the Franco-Romanian Areas where the varieties were cultivated in an ecological system, being ECOCERT RO-007 certified. Research has been carried out on the Muscat of Hamburg variety which has highlighted the content of some polyphenolic compounds comparatively in the two culture systems: conventional and ecological. The analysis of the agrobiological and technological indicators according to the ecological and agrofitotechnical supply was performed. The qualitative, productivity and yield potential of the variety has been established under the impact of the two culture systems. [ABSTRACT FROM AUTHOR]

This paper aims to highlight the superior agrobiologic potential and technologically of 21 hybrid elites, obtained by the hybridization of the varieties Muscat Iantarnîi x Canner (codified HI), Victoria x Black Pearl (codified BP) and Victoria x Victoria (codified A) and compared with the genitors. Since the hybrid elites selected from the experimental fields, have been highlighted by several descriptors, have been established correlations between all studied agro biological and technological elements: viability of the buds, total and fertile shoots, coefficient of absolute and relative fertility, The indices of absolute and relative productivity, the weight of the bunch and berry, content of the must in sugars and acidity.[1] The graphical representation of relations between quantitative and qualitative characteristics of hybrid descendants appealing to function regression and the correlation coefficient has highlighted the connections and meaning of the variables. This paper aims to highlight the superior agrobiologic potential and technologically of 21 hybrid elites, obtained by the hybridization of the varieties Muscat Iantarnîi x Canner (codified HI), Victoria x Black Pearl (codified BP) and Victoria x Victoria (codified A) and compared with the genitors. Because the selected hybrid elites in experimental fields, descendants of three types of hybridization, were highlighted by several descriptors, have been established the correlations between all studied agro biological and technological elements.
