Abstract：Inorder toscreenoutsuperior potato varieties（lines）suitable forcultivationin Hulunbuir，17potato Varieties （lines）were usedas the testmaterials.Byobserving and recording majormain agronomic traits，a comprehensive evaluation was conducted using coefficientofvariationanalysis，principalcomponentanalysis，clusteranalysisand membership functionanalysis.Theresults showed that thecoeficientof variationamong the17potato varieties（lines）ranged from 9.44% to 26.78% ，with the single plant yield exhibiting the greatst variation.The correlation analysis results showed that the numberof tubers per plant was significantly positivelycorrelated with the yield per plant.The principal component analysis results showed that the contribution rate of component l，component 2and component 3 were 33.939% 28.742% and 16.939% ，respectively.The clusteranalysis showed that when the euclidean distance was 10，the17 potato varieties （lines）could be divided intoseven groups.The membership function analysis results showed that thecomprehensive rankings ofV7，Huasong7，BL-17andDW2 wererelativelyhigh.Inconclusion，V7，Huasong7，BL-17andDW2posesexcellent germplasm resourcesand breeding potential for he Hulunbuir region.
