【中文摘要】 以 4個姬松茸菌株和 2個雙孢蘑菇菌株為材料 ,用 2 0個隨機(jī)引物對它們進(jìn)行RAPD擴(kuò)增。通過對供試菌株遺傳相似系數(shù)的估算和系統(tǒng)聚類分析 ,構(gòu)建姬松茸和雙孢蘑菇遺傳相關(guān)樹狀聚類圖譜。結(jié)果表明 ,進(jìn)行RAPD擴(kuò)增的 2 0個隨機(jī)引物中 ,有 12個能產(chǎn)生三種帶型。當(dāng)遺傳相似系數(shù)升至 0 .8713時 ,這 6個菌株被分為 3類 ,第一類為菌株 18和 2 6 ,第二類為菌株 13和 12 ,第三類為菌株 33和 4 5。

【英文摘要】 Four strains of Agaricus blazei and two strains of Agaricus bisporus were amplified by RAPD (Random Amplified Polymorphic DNA) technique with 20 random primers. A dendrogram was generated through the assessment of the similarity coefficient of these six strains tested and systematic clustering analysis. The result showed that among 20 primers tested, 12 primers could produce three band types of DNA fragments. When the similarity coefficient raised to 0.8713, six strains tested were divided into three classes. The first class included strains 18 and 26, the second class included strains 12 and 13 and the third class included strains 33 and 45.
