Agro-ecological testing of varieties and qualitative characteristics of potato tubers in the conditions of the Ryazan region

The article presents the results of the analysis of the cultivation of potato varieties for yield and quality data. The aim of the study was to determine the technological and consumer characteristics of various varieties of potato grown in the Ryazan region. During the experiments were used potato varieties of domestic and foreign selection, which were approved for zoning in the Ryazan region. Potato was cultivated at the experimental agrotechnology station of Ryazan State Agrotechnological University in 2019-2020. As a result of research, it was revealed that only the varieties “Gala”, “Queen Anna” and “Kolobok” are classified as type C, which is suitable for cooking most culinary dishes, and accordingly they are universal. According to the quality indicators “taste and smell” and “darkening of the pulp”, the tubers of the “Gala”, “Queen Anna”, “Red Scarlett” and “Kolobok” varieties showed themselves worthily. According to the number of tubers on the bush, varieties “Queen Anna” and “Kolobok” also performed best. The highest average mass of tubers was given by the varieties “Rodrigo” and “Kolobok”.
