Abstract

The article considers the issue of scion-rootstock combinations of seedless grape varieties in Russia and the world. The rootstock influences the physiological and biochemical parameters, stability, yield capacity and quality of the yield of grafted grape varieties. It is relevant to study the experience of different countries to determine the direction of research on this topic in Russia. In the world, the main research is concentrated predominantly in the countries producing table grapes: India, China, Egypt, Chile, Brazil, Greece, there are also studies from Mexico, Chile and Australia. Depending on the agro-climatic conditions, soils and terrain, appropriate rootstocks are used. High indicators of productivity, quality and resistance to stressors can be achieved in plants of the same variety on different rootstocks, for example, the yield capacity of the Thompson Seedless variety in Egypt is higher on the 1103 Paulsen rootstock, and quality indicators are higher on the Salt Creek rootstock. In Australia, the own-root variant had a higher fruitfulness of shoots, but Thompson Seedless variety grafted on Ramsey rootstock had higher yield capacity and bunch size. Scion-rootstock combinations are studied both for proven grape varieties and for new ones. Studies of variety-rootstock combinations in Russia are limited to individual works. The main rootstock for seedless varieties is Kober 5BB. Given the high role of rootstocks in increasing the abiotic and biotic stability of plantings, increasing productivity and improving the quality of grapes, the development of research in our country in the field of studying and effective use of rootstocks is relevant.
