«Aztec» – the new white table grape resistant variety
Abstract
Context and purpose of the study – This paper presents is the create, the study and amplographic description the new white Greek table variety grapes “Aztec”, created in 2013 by breeder P. Zamanidis at the Athens vineyard of the Institute of Olive, Subtropical Plants and Vine.
Material and methods – The variety created by crossing with the method of hybridization of the variety “Talisman” with the newly Greek variety “Ipirotis”. “Aztec” is a cross-breeding between American, European grapevine species and Far East varieties (V. Amurensis).
Results – The duration of the “Aztec” variety from budburst to maturity is146-155 days. The variety is very strong with large shoots growth(2,1 – 3,0 m). The growth of shoots is higher over 95%. The flowers are morphologically and physiologically hermaphrodite. The yield is moderate (30-40t grapes / ha). The size of the cluster is large with a length of 26 cm and a width 15 cm, the shape is conical, medium density. The length of the peduncle of the grape is 6 cm and the length of the peduncle of the berry is 0.9 cm. The average weight of the cluster is 600gr. The size of the berry is large,sort elliptical in shape, the berry is 25 mm long and 20 mm wide with weight 7 g, and green color. The number of seeds is 1-2 per berry. The skin is of thick and high strength. The flesh is without color with aromaticlight flavor Labrusca. The content of sugar in must is greater than 240 g /l. It has high resistance to fungal diseases, insects, high resistance to low temperatures, high resistance to drought and tolerant in Phylloxera.. The « Aztec » variety is suitable for table grape and tsipouro productionin areas withvery humidity.
Can be used as a resistance donor, in fungal diseases, low temperature andinsects, in the genetic improvement of vitisvenifera varieties.
