The Republic of Moldova has favorable soil and climatic conditions for the development of viticulture and winemaking. In recent years, in the Republic of Moldova, a special scientific and industrial interest and state status has received massive introduction into the assortment of a number of certified virus-free clones of classical European varieties. At the same time, the elements of their cultivation technology, from the production of grafted planting material to productivity, have not been studied from the point of view of the different quality of cuttings, vines, which is the relevance of the research. There were established the theoretic and practical importance of differentiated quality of rootstock vines on stings length in planting material production. In southern zone conditions of Republic of Moldova it was established the post-action of differentiated quality of vine propagating material on vineyards development and productivity clone R5 of Cabernet Sauvignon vines. The influence of different quality of rootstock vines on stings length appears at the stages of stratification, vines school efficiency, degree of clamping to permanent place, hubs vines development and growth. At the same time, there is a strict relationship between the quality parameters of the vine, the yield planting material from the vines school and their quality, survival rate in a permanent place and the growth vine bushes. It has been established that the growth and development of clone R5 Cabernet-Sauvignon vine bushes, their entry into fruiting and productivity, are manifested depending on the rootstock variety and the quality of planting material.
