Libertii, nr. 19, Craiova, RomaniaAbstractCorresponding author email: iulianratoi@yahoo.comThe study was effectuated out on a number of 12 varieties of autochthonous and foreign origin. The experience wasfounded in the year 2010. Climatic conditions were favorable for cultivation of vines in year I and II and lessfavourable in the third year after planting, when they recorded, in winter, the minimum negative temperatures (-27 °C),well below the limit of resistance of the vine and in the summer very high temperatures associated with droughtrendered and sunstroke. After planting all vines were entered in vegetation. At the end of vegetation period thepercentage of normally developed vines was between 75 and 100. In year II continued the process of planting in placesempty. In the year III (2012) have obtained the grapes on the buds situated at base of vines because the buds situatedabove the snow (about 35-40 cm thick) were perished all buds. With all these difficulties were emphasized a fewvarieties from the point of view of precocious and from the point of view of the potential to make on the short elements(2-3 eyes). From the point of view of precocious has noted the Prima Cl. 1022, that reached maturity of consumption at15.07.2012. Transilvania and the Prima Cl. 1022 varieties, were highlighted, and in terms of the production of grapes,which means they have the potential to make on the short elements. The Prima Cl. 1022 achieved 9998 Kg/ha yieldand Transilvania achived 10073 Kg/ha yield.Key words: range, sandy soils, table grapes, vine.INTRODUCTIONViticulture is an important branch of culture inour country. Culture of table grape varieties isthe second production direction for harvestersin the areas with higher heat as sandy soilsfrom Southern and South-Western Oltenia.Vine varieties with table grapes are appropriateconditions of culture in our country (Martin T.et al., 1974).In order to establish the different types of tablegrape varieties have carried out studies on theirbehaviour in different areas (Bani P.,Vldoianu Em., 1979; Costescu Adriana et al.,2012; Dumitru I. et al., 2009; Rotaru L., 2005;Mohammad A, Popa A., 2005).After an assortment of table grape varieties iscontinuous improvement a priority of thisprocess (Cichi D, Costea D.C., 2008; Popa C.et al., 2008; Popa C. et al., 2009; Stroe M.V. etal., 2012).223MATERIALS AND METHODSThe study was effectuated out on a number of12 varieties of autochthonous and foreignorigin. The experience was founded in the year2010. The climatical conditions were favorablefor cultivation of vines in year I and II and lessfavourable in the third year after planting, whenthey recorded, in winter, the minimum negativetemperatures (-27 o C), well below the limit ofresistance of the vine and in the summer veryhigh temperatures associated with drought andsunstroke.The studied varieties were the following:Silvania, Timpuriu de Cluj, Muscat deHamburg Cl. 4 Pt., Tamina, Somean,Splendid, Napoca, Victoria, Prima Cl. 1022,Coarn neagr selecionat, Muscat deHamburg Cl. 202, Transilvania. Were planted20-40 vines from each variety. Thefertilization, at land preparation, made with 60t/ha manure, 300 kg/ha Complex 15 15 15. Atplanting were applied 5 Kg/pit
