摘　　要：为探索雷达图分析法在特色马铃薯品种筛选中的适用性,以费乌瑞它为对照,对引进的黑美人、红宝石、后旗红、台湾红皮、丽薯7号、紫云1号等6个特色马铃薯品种采用雷达图分析法进行综合评价分析。研究从产量、薯型、肉色、晚疫病抗性等9个方面进行综合评价,将马铃薯的评价指标数据进行标准化及无量纲化处理,绘制雷达图,并构建基于雷达图面积和周长的综合评价函数,用于计算各参试品种综合评价值,给出综合评价结果。结果表明:各参试品种综合评价排序为黑美人>紫云1号>丽薯7号>后旗红>红宝石>费乌瑞它(CK)>台湾红皮。结论:雷达图分析法适用于特色马铃薯品种的筛选综合评价,该方法较常规方法客观、科学。A comprehensive evaluation and analysis system of featured potatoes was proposed based on radar chart plotting in the study. Taking Favarita as the control, six featured potato varieties including Heimeiren, Hongbaoshi,Houqihong, Cardinal, Lishu 7 and Ziyun 1 were synthetically analyzed for nine factors such as yield, tuber type, tuber flesh color and resistance to late blight and so on. A radar chart was plotted after the evaluation data was taken standardization processing and nonlinear variation. Furthermore, an evaluation function was established on the basis of the area and circumference of the radar chart. By calculating the data with the function, the evaluation results of the varieties were ranked as Heimeiren〉 Ziyun 1 〉 Lishu 7 〉 Houqihong 〉 Hongbaoshi〉 Favarita （CK） 〉 Cardinal. Conclusion. the radar chart method is suitable for comprehensive evaluation of screening featured potato varieties. This method is more objective and scientific than the conventional methods.
