Abstract
In terms of production volume, nutritional value and consumption level, potatoes in Kazakhstan are among the priority crops. The area of potatoes in the republic reached 210 thousand hectares, the gross harvest exceeded 4 million tons. However, average yields are still low (18-19 t / ha). In increasing the productivity of potatoes, the selection of highly productive varieties is of great importance. The agro-climatic potential of the regions of Kazakhstan favors the cultivation of a wide variety of potato varieties. In this case, it is necessary to use potato varieties approved for use for a particular region. More than 120 varieties of potatoes are included in the "State Register of Breeding Achievements Admitted for Use in the Republic of Kazakhstan", of which about 55% are of foreign breeding. For the southeast of Kazakhstan, about 30 foreign varieties have been approved for use. However, most of them do not possess a set of economically useful properties. In this aspect, it is necessary to create varieties that differ in many valuable traits. For potato farms, along with productivity, quality indicators and preservation during storage, resistance to harmful diseases and stress factors of the external environment are also of great importance. Therefore, studies on the study of adaptive properties and the assessment of economically valuable traits of new potato varieties are highly relevant, which led to this work. In the conditions of the foothill zone of the southeast of Kazakhstan, at the scientific station of the laboratory of selection, seed production and biotechnology of potatoes of the Regional branch "Kainar"LLP "Kazakh Research Institute of Fruit and Vegetable Growing" a variety study of potatoes was carried out. In 2018-2020, 39 varieties of potatoes of foreign selection and 14 somaclones obtained by the method of cell selection from foreign varieties Aladdin and Nevsky were tested.
