摘要
选用香菇的一个野生株（Ｑ）与一个栽培株苏香（Ｓ）的４种孢子单核体进行双单杂交，获得四个杂交后代。栽培结果表明：１，２，４号菌株产量明显高于双亲产量，其中以２号菌株产量最高，其生物转化率为８６９１％，产量优势为２１２９％，３号菌株产量高于双核体亲本Ｑ，其杂种优势显著。
Four hybrids were obtained from the di-mon mating of wild strain (Q) and four types of sporualated monokaryons. The cultivation result showed that yield of strain No 1, 2 and 4 was obviously higher than their parents and No.2 of which yield was the highest and its biological efficiency was 86 9% and its heterosis of yield was 212 9%, and yield of No.3 was higher than its parent Q, showing a marked hybrid vigour.
