摘　　要：为了更全面地评价并筛选适宜设施二次果生产的葡萄品种,基于综合评分法和主成分分析法综合考量了二次果的果实内在品质、结果能力、外观品质、产量稳定性和成熟期,以及抗病性、劳动强度、叶片衰老情况和市场定位9个因素,对38个品种进行分析评价。主成分分析结果显示,共提取4个主成分,方差累积贡献率为75.486%,根据提取主成分的综合得分确定了品种排名,‘玫瑰香优系’、‘户太8号’、‘意大利’、‘巨玫瑰’得分较高,综合表现突出,‘黄玫瑰’、‘巨峰’、‘魏可’和‘亚历山大’等综合表现良好,该结果可以为我国北方地区设施二次果生产提供品种参考。In order to more comprehensively evaluate and select grape varieties suitable for second-harvest fruit production in facilities,38 grape varieties were analyzed and evaluated.Based on the comprehensive scoring method and the principal component analysis method,9 factors were comprehensively considered,including the inner fruit quality,bearing capacity,exterior quality,yield stability,ripening period,disease resistance,leaf senescence,labor intensity and market positioning.A total of 4 principal components were extracted in the experiment,and the results showed that the cumulative contribution rate of the variance was 75.486%.The ranking of each variety was determined according to the comprehensive score of the extracted principal components.The comprehensive performance of'Muscat Hamburg superior strain','Hutai 8','Italy'and'Jumeigui'was outstanding,with higher scores,followed by'Yellow Rose','Kyoho','Wink'and'Alexander'.The results could provide a variety reference for the second-harvest grape production in facilities of northern China.
