Abstract: As one of the main food crop, potato has rich nutrition, and is known as the “underground apple” laudatory name. To meet the demand for high-yield and good-quality new potato varieties, the yield, quality and disease resistance were performed on 20 new potato varieties (lines) in Yuzhong County of Gansu Province in 2017, using "Longshu 7" as the control. The results showed that, "Longshu 10", "Longshu 7" and "Longshu 12" had such advantages as high yield, wild adaptability, strong disease and drought resistance and high marketable tuber percentage, the yield of "Longshu 10" was the highest, up to 35175.90 kg/hm2, compared with the control, yield of "Longshu 10" was increased by 6.03 %, so "Longshu 10" could be recommended for planting in this area. Considering marketable tuber percentage and taste, "Longshu 7" and "Longshu 12" should be appropriately expanded this area after further evaluation.
