| 摘 要： | 对中国32个木耳Auricularia auricula-judae主要栽培菌株的生物学特性进行了系统分析,在此基础上分别对27个生物学特性指标赋值,运用UPGMA聚类法及PCO主坐标分析法对木耳种质资源的遗传多样性进行研究。研究结果显示中国木耳栽培种质的遗传多样性丰富,32个供试菌株在生物学特性指标上均存在着一定差异;供试菌株聚为3个主要类群,分别包含大部分东北地区菌株,中部及东南部地区菌株,华北华南及部分中部地区菌株;表明生物学特性与地域来源呈一定相关性,同一地域来源的栽培菌株相似度更高,部分菌株间存在着同物异名现象。

| Abstract: | The physiological characteristics of 32 main cultivated strains of Auricularia auricula-judae in China were analyzed, and the 27 indexes were evaluated and clustered by UPGMA and PCO. The results demonstrated that the cultivated germplasm of A. auricula-judae in China are richly endowed with genetic diversity, and the 32 strains analyzed are different physiologically. The strains can be divided into 3 groups, group of strains mainly cultivated in northeast region, group of strains in central and southeast regions, and group of strains in north, south and part of central regions. It is revealed that the physiological characteristics significantly correlated with geographical origins. The cultivated strains in the same region are more similar physiologically and some strains are suspected to be synonymous. |
