摘　　要：通过分析35份木瓜单株的主要外观、营养和功能品质,筛选表现优良的木瓜单株,为木瓜品种选育和综合开发利用提供理论支持。以分布在陕西省白河县的35份不同性状木瓜单株为材料,采用聚类、相关性和主成分分析法对果实的13项品质指标进行综合评价分析。木瓜单株13项指标的变异系数在11.63%~45.89%,其中单果质量、糖酸比、总黄酮含量的变异系数较大,可溶性固形物含量的变异系数最小。对35份木瓜进行聚类分析,共分为3个类群,第Ⅰ类群可作为加工果醋、果酒的原料,第Ⅱ类群可用于开发中药材,第Ⅲ类群可作为观赏性木瓜使用。主成分分析共提取功能、酸度、甜度、果形4个主成分因子,累计方差贡献率达79.873%,通过综合评价方程得到不同木瓜单株的综合得分,排名靠前的4份优良单株分别为BH2、BH4、BH33和BH30。研究结果可为木瓜单株利用与新品种选育提供理论依据。By analyzing the main fruit appearance quality,nutritional quality and functional quality of 35 Pseudocydonia sinensis plants,those with excellent performances were screened out to provide theoretical support for the P.sinensis variety selection and comprehensive development and utilization.Fruits coll-ected from 35 individual P.sinensis plants distributed in Baihe County,Shaanxi Province were used as materials,cluster analysis,correlation analysis and principal component analysis were adopted to comprehensively evaluate and analyze 13 quality indexes of the fruits.The coefficients of variation of the 13 indexes ranged from 11.63%to 45.89%,among which the quality indexes with larger coefficients of variation were single fruit mass,sugar-acid ratio and total flavonoids,and the smallest one was soluble solids.The results of clustering analysis indicated that the samples collected from 35 individual plants were divided into three groups based on the application functions:raw materials for processing fruit vinegar and fruit wine,for medicinal herbs,and for ornamental purpose.Four principal factors,with a cumulative contribution rate of 79.873%,were extracted from the principal component analysis,namely function,acidity,sweetness and fruit shape.The four excellent individual plants BH2,BH4,BH33 and BH30 with the top comprehensive scores were obtained through the comprehensive evaluation equation.The results of the study provide theoretical basis for the utilization of P.sinensis fruit,as well as for the new variety selection and breeding.
