摘　　要：榆耳是我国东北地区食药用菌之一,对肠胃系统疾病具有极高的治疗效果,在中国已开始推广栽培,但目前尚不清楚哪些性状主要受遗传因素影响,哪些性状主要受环境因素影响,也无区分品种间性状差异的标准。因此本研究对26个榆耳性状进行R型聚类分析和主成分分析,明确DUS测试性状。结果表明,榆耳农艺性状具有较大的差异,R型聚类分析可知性状间具有较好的相关性,在欧氏距离3.57处,可将性状分为两大类。主成分分析可知性状的提取值大多数都在0.9以上,性状重要性均较高,将26个性状分为9个主成分,累计贡献率达到94.458%,筛选出12个性状为榆耳种质资源评价的主要指标。本研究旨在为榆耳的品种保护提供依据,从而推动产业的健康可持续发展。Gloeostereum incarnatum is a rare edible and medicinal fungus in China,with high therapeutic effect on gastrointestinal diseases.It has been popularized and cultivated in China.However,traits mainly affected by genetic and environmental factors are still imperfectly known,and the differences of traits between varieties also have not been standardized.In this study R-model cluster analysis and principal component analysis on 26 G.incarnatum traits are conducted.R-model cluster analysis showed that there was evident correlation between agronomic traits of G.incarnatum.At the Euclidean distance of 3.57,the traits could be divided into two categories.The results of principal component analysis showed that most of the extracted values of traits were above 0.9,and the importance of traits was high.The 26 traits were divided into 9 principal components,and the cumulative contribution rate reached 94.458%.In total,12 traits regarded as main indicators for evaluation of G.incarnatum germplasm resources are screened.This study provides basis for variety protection and promoting sustainable industrialized development of the G.incarnatum.
