摘　　要：以收集的57份蝴蝶兰种质资源为研究对象,对其23个生物学性状进行调查并分析,明确影响蝴蝶兰种质资源生物学性状综合评价的主要因子,采用层次分析法与K-Means聚类分析方法相结合,建立蝴蝶兰种质资源生物学性状综合评价体系,以期能够较为全面的评价现有种质,对现有种质资源进行分级,为蝴蝶兰种质资源的利用、新品种选育及栽培推广提供参考依据。结果表明:花部形态(C1)是蝴蝶兰综合性状评价的主要因子,花色所占比重最大,花梗形态(C2)次之,植株形态(C3)权重最低;综合评价得分最高的是‘光芒四射’(得分4.2706);花部形态评价得分最高的是‘招财猫’和‘光芒四射’(得分2.5010),植株形态得分最高的是‘龙树枫叶’(得分0.7472),花梗形态得分最高的是‘1713’(得分1.1554);根据评价得分将57份种质分为4个等级,其中优秀等级9个,占比15.79%;良好18个,占比31.58%;中等20个,占比35.09%;及格10个,占比17.54%。With 57 Phalaenopsis germplasm resources collected as research objects,23 biological traits were investigated and analyzed to clarify the main factors affecting the comprehensive evaluation of the biological traits of Phalaenopsis germplasm resources,and the hierarchical analysis method was combined with the K-Means clustering analysis to establish a comprehensive evaluation system of the biological traits of Phalaenopsis germplasm resources,so as to be able to evaluate the existing germplasm comprehensively and classify existing germplasm resources for reference in the utilization,selection and breeding of new varieties and cultivation promotion of Phalaenopsis.This system was intended to evaluate the existing germplasm in a more comprehensive way,to classify the existing germplasm resources,and to provide reference for the utilization of Phalaenopsis germplasm resources,the selection and breeding of new varieties,and the promotion of cultivation.The results showed that floral morphology(C1)was the main factor in the comprehensive trait evaluation of Phalaenopsis,flower color accounted for the largest proportion,pedicel morphology(C2)was the second largest,and plant morphology(C3)was the least weighted;the highest score in the comprehensive evaluation was‘Guangmangsishe’(score 4.2706);the highest scores in the evaluation of floral morphology were‘Fortune Cat’and‘Guangmangsishe’(score 2.501),the highest scoring plant form was‘Longshufengye’(score 0.7472),and the highest scoring pedicel form was‘1713’(score 1.1554);57 germplasm were categorized into 4 grades based on the evaluation scores,including 9 excellent grades,accounting for 15.79%;18 good grades,accounting for 31.58%;20 medium grades,accounting for 35.09%;and 10 passing grades,accounting for 17.54%.
