聚类分析在金针菇杂交育种中的应用

对12个金针菇菌株两种生化标记（酯酶和可溶性蛋白）进行了筛选研究．采用多元统计方法，进行聚类分析。结果表明，供试菌株可分为四个类群。按照亲本的遗传相似系数，对各杂交组合的杂种优势进行了检测，实际结果表明，不同杂交组合的产量与预测结果基本一致。群内组合为低产组合，群间组合杂种优势较强。

APPLICATION OF CLUSTER ANALYSIS IN CROSSBREEDING IN FLAMMULINA VELUTIPES

Two biochemical markers (esterase, soluble protein) were screened in 12 strains of Flammulina veinlutipes.Cluster analysis based on coefficient of genetics similarity among the strains of Flammulina velutipes was carried out by UPGMA. Classification of the 12 tested strains were subdivided into four groups. The results based on the coefficient of genetics similarityto select parents for hybridization and predict their heterosis of the tested hybrid strains were coincided with their actual yields. Heterosis of hybrid combinahons among groups were found higher than within groups.
