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.
