The soil of experimental plot is sod-podzolic, light loam, highly cultivated. The highest yield on the 60-65 day was obtained from hybrid 1657-7 - 11.4 t / ha and exceeded the control varieties by 50.0% and 15.1%, respectively. Varieties of Saranac and Memory Field it was 10.2-8.9 t/ha. 90-95 day, from the date of planting, the average yield of varieties and hybrids of potatoes amounted to 26.2-38,0 t/ha. The highest yields of potato tubers obtained from the hybrid 1657-7 - 38,0 t/ha, a fairly high yield of potatoes was the varieties Saranac - at 33.9 MT/ha and Memory Field - 32.0 t/ha. dry matter content in tubers of potato varieties: Saranac - 21,7 %, P Field -23,4%, in the control potato varieties it was 20.8 and 21.3%.
