Abstract

The article presents the results of research on the basis of which the most productive high-yielding potato varieties have been identified, the genetic potential of which can be realized when cultivated in the conditions of the Moscow region. In the conditions of field experiment, an agroecological assessment of new promising potato varieties of Russian and foreign breeding was carried out. The tasting evaluation of varieties under VNIIKH methodology according to a set of assessments showed that the varieties had the highest taste qualities: Nadezhda, Severnoye Siyanie, and Vector, while the Nadezhda variety received the highest score (53.4). Potato yield on average for two years was largely determined by the climatic provision of vegetation conditions and variety adaptive ability to adapt to changing conditions: for the Pamyati Lorkha variety, conditions were favorable in the formation of yield at the level of 39 t/ha, while there was an increase in the total yield structure of the proportion of seed (50-80 g) tubers, during tuber formation of the Kumach variety humidification conditions were unfavorable, which was reflected in the formation of the yield subsequently at the level of 23.2 t/ha, while an increase in the proportion of tubers of non-commercial fraction was noted.
