Early Elgo Demetra: the new pink table variety seedless with big berry and resistant

Abstract

Context and purpose of the study – This paper presents is the create, the study and amplographic description the new pink “Early Elgo Demetra” variety. The seedless resistant grape variety “Early Elgo Demetra” was created by P. Zamanidis at the Athens Vine Department of the Institute of Olive and Subtropical Plants, in 2014.

Material and methods – The variety created by crossing with the hybridization method of the Russian resistant table variety “Talisman” with the newly Greek variety “Volga” (“Talisman” with a mixture of pollen “Perlet” and “Sultanina”). Created variety is a complex hybrid between dissimilar species of European, American and Far East (V. Amurensis). 

Results – The duration of the “Early Elgo Demetra” variety from budburst to maturity is 126-135 days. The variety is strong with very large shoots growth (2.1 – 3.0 m). The growth of shoots is higher over 95%. The shoot and the tip of the young shoot are green-colored and hairless. The yield is high more than 40 t / ha. The average weight of the cluster is 700 g. The content of sugar is high. The “Early Elgo Demetra” grape is large, conical, low density, with a long elliptical shape, pink color, with an average weight of until to 8 g, and has small pseudo-seed that are not understood in consumption. The mature leaf is medium size, symmetrical, and five sort lobs. The berry is sort elliptical with skin is thin and high resistance. The flesh has a pleasant taste. The grape is kept on for a long time. It is intended for edible use. It is kept for a long time in refrigerators and has excellent transport behavior. It has high resistance to fungal diseases, insects, high resistance to low temperatures, high resistance to drought and tolerant in Phylloxera compared to other varieties of Vitis vinifera. Can be used in the genetic improvement of Vitis vinifera varieties as a resistance donor, for fungal diseases, insects and low temperature.

Caractérisation des terroirs viticoles champenois

The Champagne vineyard extends over 35,300 ha under the Appellation d’Origine Contrôlée, of which 30,000 are in production. It mainly covers 3 departments: in order of importance, Marne (68% of the appellation area), Aube (22%) and Aisne (10%), and more anecdotally Haute Marne and Seine and Mame. It is a young vineyard (for more than half of the surface, the winegrowers have the experience of only one generation of vines), and fragmented (more than half of the exploitations extend over less than 1 ha; the average size of a cadastral parcel is 12 ares).

Présentation d’une méthodologie de caractérisation des terroirs et valorisation par l’étude de l’effet terroir sur la typicité et l’originalité du produit vin dans la région des Côtes du Rhône

In the global economic context, an Appellation d’Origine Contrôlée must now more than ever control the typicity and originality of the wines it produces. It is in this spirit that the Côtes du Rhône have decided to acquire the means necessary for this control.

A lower rate of grape berry transpiration delays ripening and reduces flavonoid content

Exposing berries to solar radiation improves most berry composition traits. Many of these effects have been linked to photomorphogenic mechanisms and berry temperature.

Differences in metabolism among species and hybrids of the genus Saccharomyces during wine fermentation unveiled by multi-omic analysis 

Yeast species S. cerevisiae, S. uvarum, S. kudriavzevii and their hybrids present clear metabolic differences, even when we compared S. cerevisiae wine versus wild strain. These species and hybrids produced significantly higher amounts of glycerol, organic acids, 2,3-butanediol, and 2-phenyl ethanol and a reduction of the ethanol yield, properties very interesting in the sector to deal with climate change effects. To understand the existing differences, we have used several omics techniques to analyze the dynamics of the (intra- and extracellular) metabolomes and/or transcriptomes of representative strains of S. cerevisiae, S. uvarum, S. kudriavzevii, and hybrids.

How different SO2 doses impact amino acid and volatile profile of white wines

Sulphur dioxide (SO2) is a well-established preservative in the wine industry. Its ability to act in different stages of the process as an antioxidant and an antiseptic as main characteristics makes it versatile. However, the need for its reduction or even its replacement has been increasing by the regulatory authorities as well as by the final consumer. To understand the impact of SO2 during ageing on volatile organic compounds (VOCs) and amino acids (AAs) profiles, two white wines (one varietal and one blend) were aged under the same conditions, in the presence of different doses of SO2. After fermentation (t=0), 0, 30, 60, 90 and 120 mg/L of SO2 were applied, wines were kept over lees for 3 months (t=3), then were bottled after 3 (t=6) and 9 (t=12) months.
