摘　　要：为更精准地筛选出适合定西地区栽培的优良辣椒品种,本文采用主成分分析和聚类分析对25个引进的辣椒品种的10个指标进行综合性评价。结果表明,通过对主成分分析构建的3个主成分因子的定量函数模型计算得出,‘天椒20’‘运驰’‘肃椒19号’‘肃椒22号’‘天椒16’‘2774’这6个品种综合性状得分最高。利用聚类谱系图对不同辣椒品种进行系统分类,将25个品种依据10个性状指标聚成三大类,其中‘天椒16’‘2774’‘运驰’‘肃椒19号’‘肃椒22号’‘天椒20’6个品种聚为一类,表现为果长较长,单果质量大,产量高,综合性状好;该结果与田间生长情况基本一致,说明综合评价结果的可靠性较高。综合分析表明,‘天椒16’‘2774’‘运驰’‘肃椒19号’‘肃椒22号’‘天椒20’这6个品种适宜在定西地区进行栽培,是适宜推广并具有广阔市场潜力的品种。In order to more accurately screen out high-quality pepper varieties suitable for cultivation in Dingxi region,this paper used principal component analysis and cluster analysis to conduct a comprehensive evaluation of 10 indicators of 25 introduced pepper varieties.The results showed that the quantitative function model,constructed based on three principal component factors,indicated that the six varieties,including‘Tianjiao 20’‘Yunchi’‘Sujiu 19’‘Sujiu 22’‘Tianjiao 16’,and‘2774’had the highest comprehensive trait scores.By using the cluster dendrogram to systematically classify different pepper varieties,the 25 varieties were clustered into three major categories based on 10 trait indicators.Among them,the six varieties of‘Tianjiao 16’‘2774’‘Yunchi’‘Sujiu 19’‘Sujiu 22’‘Tianjiao 16’had longer fruit lengths,larger single fruit weights,higher yields,and good comprehensive traits.This result was basically consistent with the field growth situation,indicating that the reliability of the comprehensive evaluation results was relatively high.The comprehensive analysis showed that‘Tianjiao 16’‘2774’‘Yunchi’‘Sujiu 19’‘Sujiu 22’,and‘Tianjiao 20’were suitable for cultivation in Dingxi region and were varieties with market potential.
