"THE DEGREE OF ACCUMULATION OF X, M, S-POTATO VIRUSES IN VARIOUS PARTS OF PLANTS "

The article deals with the potato used to solve some problems of the implementation of sustainable development goals in our republic. Ways of virus damage to potato, which is widely used in crop production, are provided. Materials on the localization of X, M, S viruses mainly in the apical part of the tubers, including their sprouts, have been carried out; in the light sprouts from the umbilical part of the tuber, these viruses are found by 10–15 % less frequently than in the apical ones. In vegetative potato plants of the studied varieties, in various organs and parts of X, M, S, viruses have different serological titers, it is highest in the leaves of the upper tier, and lower in the reproductive organs. Damage to the reproductive organs of the plant is directly related to the environment and abiotic factors. Unfavorable factors have a negative effect on the reproductive organs of the plant and reduce the quality of the product.The degree of accumulation and concentration of viruses, in turn, is decisively reflected in the clarity of the course of serological reactions carried out with certain parts and organs of potato plants. These indicators are practically important information for potato production centers. It is urgent to find ways to fight viruses in potato cultivation in our country. These studies are important for increasing the quality and quantity of the product. Increasing the quality of products for the purposes of sustainable development is a solid step in strategic development. In this regard, it is true that researches on damage and quality production of important species in agriculture are relevant.
