The hydrothermal coefficient (SCC) for the period "shoots - the end of flowering," defined the potato yield is almost the same as the temperature - r = 0,79 ± 0,09 ± 0,74 and 0,09 respectively for the early and Medium early varieties and hybrids . Model based yield and early maturing varieties of potato hybrids from SCC has the form y = -14,79H2 ± 49.1 X 0.57. The correlation coefficient between the temperature and the number of tubers under a bush r = -0,76 ± 0,22), the Middle-reacted change in weight of tubers. The correlation between the air temperature in the period of budding and average weight of marketable tuber in Middle-grades and hybrids reached r = -0,73 ± 0,22. growing period of the year, weather conditions have an impact on the productivity and quality of seed potatoes in the coming year. The relative decline in the harvest tuber varieties and hybrids of the second year of competition and environmental tests in comparison with the first is from 0 to 93%. The closest correlation was found between the sum of effective temperatures in May and June and a decrease in the harvest of next year when used for planting the tubers of biological maturity - r = 0,496 ± 0,078.
