Abstract: 【Objective】To screen potato varieties with excellent comprehensive characters,outstanding processing characteristics and suitable for planting in Ulanqab,Inner Mongolia,and to provide high-quality materials for breeding and germplasm improvement of new varieties.【Methods】The yield and nutritional quality were evaluated by variance,path,clustering and correlation analysis.【Results】The results of nutritional quality evaluation was as follows:HR066>HR052> YS024>D034>LK99>YS017>Xisen 3>Yunshu 10>HR068>D048>D037>Jizhangshu 12(CK1)>Zhongshu 9>Huashu 1>HR090>Longshu 5>YS008>Shepody(CK2)>YS001>HR075>YS022>YS033; The potato varieties were divided into 3 categories by cluster analysis, CategoryⅠ:YS001,Zhongshu 9,HR090,Huashu 1,HR068,YS033,HR075,Longshu 5,Shepody,YS022,LK99 and Yunshu 10,which were Fried processing categories.Category Ⅱ:D034,HR052 and HR066,which were all powder processing types.Category Ⅲ:D037,D048,YS017,Jizhangshu 12,YS008,Xisen 3,YS024,which were fresh food types.【Conclusion】Six potato germplasm materials with outstanding processing characteristics were screened out,which were significantly better than Jizhangshu 12(CK1) and Shepody (CK2).Among them,D034,HR052 and HR066 were suitable for starch processing,YS017 and D037 were suitable for fresh food,and Yunshu 10 was suitable for frying.
