  • 摘要:

    Four elite clonal accessions of Vitis vinifera L., Chasselas doré variety were identified in a very old plantation, of 110 years, located in Valea Cãlugãreascã, on the St. Nicolas Monastery vineyard. The vines, grafted on the SO4 (Selection Oppenheim 4) rootstock, were planted in 2007 in the germplasm collection belonging to the Research and Development Institute for Viticulture and Enology, Valea Cãlugãreascã. The evaluation of elite clonal accessions focused on the duration of their phenological cycles, grape fertility and productivity, resistance to diseases, quantity and quality of the grapes production. The elite clonal accessions have been distinguished from Chasselas doré through the grape production which is double at one of elite and higher for the other elites as a results of the average weight of the grapes. The potential of sugar accumulations in the must was approximately twice at the elite clonal accessions, with balanced total acidity and pH values. The elites will be further studied for confirming the genetic stability and to propose the most competitive for homologation.
