«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.

Influence of must fining on oxygen consumption rate, oxidation susceptibility and electrochemical characteristics of different white grape musts

AIM: Pre-fermentative fining is one of the central steps of white wine production. Mainly aiming at reducing the levels of suspended solids, juice fining can also assist in reducing the content of oxidizable phenolics and therefore the susceptibility of juice to oxidation.

Current climate change in the Oplenac wine-growing district (Serbia)

Serbian autochthonous vine varieties Smederevka (for white wines) and Prokupac (for rosé and red wines) are the primary representatives of typical characteristics of wines and terroir of numerous wine-growing areas in Serbia. In the past, these varieties were the leading vine varieties, however, as the result of globalization of winemaking and the trend of consumption of wines from widely prevalent vine varieties, they were replaced by introduced international varieties. Smederevka and Prokupac vine varieties are characterized by later time of grape ripening, and relative sensitivity to low temperatures. Climate conditions can be a restrictive factor for production of high-quality grapes and wine and for the spatial spreading of these varieties in hilly continental wine-growing areas.
This paper focuses on the spatial analysis of changes of main climate parameters, in particular, analysis of viticultural bioclimatic indices that were determined for the purposes of viticulture zoning of wine-growing areas in the period 1961-2010, and those same parameters determined for the current, that is, referential climate period (1988-2017). Results of the research, that is, analysis of climate changes indicate that the majority of examined climate parameters in the Oplenac wine-growing district improved from the perspective of Smederevka and Prokupac vine varieties. These studies of climate conditions indicate that changes of analyzed climate parameters, that is, bioclimatic indices will be favorable for cultivation of varieties with later grape ripening times and those more sensitive to low temperatures, such as the autochthonous vine varieties Smederevka and Prokupac, therefore, it is recommended to producers to more actively plant vineyards with these varieties in the territory of the Oplenac wine-growing district.
