摘要
应用主成分分析-逼近理想解排序法对不同辣椒品种现蕾期耐高温多湿性进行了评价和分类。10个供试品种按耐热耐湿由强到弱划分为高度耐热耐湿(592、597)、中度耐热耐湿(114、512、435)、不耐热耐湿(451、115、590、499)、极不耐热耐湿(591)4类。结果表明:综合评价结果与田间实际基本一致,该方法操作简单,便于实际应用。
Using a newly-developed combination of PCA（principal component analysis）and TOPSIS（technique for order preference by similarity to ideal solution）, a study was carried out to evaluate and classify the high temperature and air humidity resistance in hot pepper varieties at the budding stage. Results showed that 10 tested varieties could be divided into four classes of tolerance. The most tolerant varieties were 592 and 597, followed by 114, 512, 435. The less tolerant were 451, 115, 590 and 499. The rest variety 591 was not tolerant at all. The conclusion of PCA-TOPSIS was similar to those assessed in open filed in summer. The PCA-TOPSIS method is so simple and convenient that it can be easily used to rank different varieties＇ resistance by multiple traits.
