【中文摘要】 利用RAPD技術 ,對香菇非對稱雜交的親本與后代之間的遺傳相關性進行了分析。2 0個隨機引物共擴增出 4 7條DNA片段 ,在此基礎上分析構建了遺傳相關聚類圖。結果表明 ,非對稱雜交的后代 ,其遺傳距離與單核受體較近 ,遺傳相似性在 85%左右 ,而與雙核供體遺傳距離較遠 ,遺傳相似性在 61%左右

【英文摘要】 The genetic similarity among the acceptor parent, donor parent and filial generations of nonsym- metrical crossing Lentinula edodes was analyzed with RAPD technigue. 47 DNA fragments were amplified by 20 random primers. And the dendrogram of genetic correlation was constructed on this basis. The result showed that the genetic characters of nonsymmetrical crossing filial generations were similar to that of the mononuclear accepter-parent with a genetic similarity index of about 85%, and that more genetic diversity exsisted between the nonsymmetrical crossing filial generation and the binuclear donor parent with a genetic similarity index of about 61%.
