摘　　要：以10个芸豆品种为研究对象,采用主成分分析法对其9个农艺性状进行了研究。结果表明,提取的3个主成分能够解释所有性状信息的92.142%,第1主成分贡献率为57.056%,第2主成分贡献率为24.901%,第3主成分贡献率为10.185%,主成分1代表芸豆株型与产量因子,主成分2代表株高与生育期因子,主成分3代表荚长和单荚粒数因子,综合因子代表芸豆品种综合表现,综合得分前4位的品种分别是YQ6、YQ5、YQ2和YQ7,与品比分析结果具有较好的一致性。该法可很好地应用于芸豆品种综合评价与筛选研究,为芸豆多品种综合评价及品种筛选提供一种新的途径和方法。The principal components analysis was used to research nine agronomic traits of ten kidney bean varieties. The results showed that the contribution ratio of accumulated variance reached 92.142%, and 3 principal components reflected character of relative characteristics of nine agronomic traits. The first principal component was a factor of plant-type and yield with 57.056% contribution rate, the second principal component was a factor of plant height and growth period with 24.901% contribution rate, and the third principal component was a factor of pod length and num- ber of pods per plant with 10.185% contribution rate. The comprehensive factor represented the comprehensive performance of kidney bean, the comprehensive score of the top four varieties were YQ6, YQ5, YQ2 and YQ7, respectively. The results were consistent with the results of the comparative analysis of varieties. The evaluation method of kidney bean is practicable and is a new way for kidney bean multiple varieties comprehensive evaluation.
