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.

Phenology, thermal requirements and maturation of the SR 0.501-17 wine grape hybrid cultivated in contrasting climate

The use of hybrids in viticulture is one of the alternatives for sustainable production in hot and rainy regions during grapevine maturation. This sustainable production concerns the reduction of pesticide use, adaptation to climate and control of vine decline. The SR 0.501-17 wine grape hybrid, developed in the grapevine program of the Agronomic Institute of Campinas (IAC), is characterized by producing white grapes with small spherical berries with seeds. The agronomic characterization of this hybrid, especially in different climatic conditions, as well as the evaluation of its performance in winemaking are necessary. The objective of this work was to characterize the duration and thermal requirements of the different phenological stages and the influence of rainfall on the physicochemical characteristics of the must in two contrasting climate regions of the State of São Paulo.

Importance of matrix effects (wine composition) on protein stability tests of white and rosé wines

The presence of unstable proteins in wines can affect their stability and clarity. Before bottling, winemakers need to be sure that the wine is stable. A large number of stability tests have been proposed, usually based on heating a sample with a specific time-temperature couple. In practice, none is effective to accurately assess the risk of instability. Moreover, the interpretation of the results of these tests changes according to the region.

WHAT’S FUTURE FOR SANTORINI’S VITICULTURE IN THE CONTEXT OF CLIMATE CHANGE

The own-rooted vineyard of Santorini is a unique case of vineyard worldwide that is been cultivated for thousands of years. On the island’s volcanic soil, the vines are still cultivated with traditional techniques, which are adapted to the specific and extreme weather conditions that prevail on it. While climate change is a reality in the Mediterranean region, will Santorini vineyard endure its impact? The study of the traditional training systems, techniques and vine density, as well as the application of sustainable solutions (cover crops and use of kaolin etc.) revealed sustainable methods for the adaptation of the local viticulture to new climatic phenomena that tend to be more and more frequent in the region due to climate change.
