This paper presents the results of a study of promising Russian potato varieties for the production of French fries in various soil and climatic conditions of Russia. The objective of the study was to evaluate promising Russian potato varieties Vostorg and Avatar in comparison with similar foreign varieties Innovator and Challenger, which are most in demand for domestic processing into French fries in terms of yield, average tuber length, dry matter content, and color index of the finished product. Field trials were conducted in 2024–2025 at agricultural enterprises in three regions. Agrotechnical methods of cultivating the varieties included soil preparation by autumn no-till plowing to a depth of 35 cm and spring milling to a depth of 20 cm with cutting ridges; planting in the third ten-day period of April with different planting rates (32–40 thousand units/ha); application of fertilizers with varying N:P:K doses by region; care of plantings, including pre-planting treatment of tubers, application of herbicides, 6–8-fold treatment with fungicides and 1–2-fold treatment with insecticides. The tests showed that the promising Russian varieties Vostorg and Avatar are not inferior to their foreign analogues Innovator and Challenger in terms of economically valuable traits in all the studied soil and climatic conditions, and surpass them in a number of indicators. The best results in terms of yield of all variety samples were noted in the Tambov region. The recommended planting rates for tubers for the Vostorg variety: 32 thousand pcs./ha in the Tambov region and 40 thousand pcs./ha in the Bryansk region; for the Avatar variety: 36 thousand pcs./ha - Tambov region, 40 thousand pcs./ha - Bryansk region. The soil and climatic factors of the Astrakhan region do not allow growing high-quality raw materials for the production of French fries under the conditions of existing technologies and harvesting periods (beginning of the September) due to insufficient dry matter content in the tubers.
Key words: potatoes, promising Russian varieties, yield, dry matter content, French fries, soil and climatic conditions
