느티만가닥버섯 해송이 품종의 우수 균주를 선발하기 위하여 각기 다른 자실체에서 분리한 균을 Di-mono 교배하여 균을 선발하였다. 교배한 균주를 PDA에서의 균사생장 조사를 통하여 균사생장이 좋은 3균주를 선발하였다. PDA배지에서 10일간 배양했을 때 균사생장은 3번 균주가 62mm로 가장 빠르고, 7번 균주가 58mm, 그리고 2번, 10번, 9번순이었다. 선발된 3균주, 즉, KNCAF-H-3, KNCAF-H-7, KNCAF-H-2는 톱밥배지에서 10일간 배양한 결과 각각 79mm, 76mm, 73mm의 균사생장을 보여, 대조 품종인 그린피스 5호의 55mm보다 균사생장이 좋았다.
To select the superior strain of Haesongi, Hypsizigus marmoreus, strains were isolated by Di-Mono mating with isolates from different fruit bodies. Three strains were selected to superior isolates that are good mycelial growth on PDA medium for 10days. When cultured on PDA medium for 10 days, strain No. 3 and strain No. 7 showed mycelial growth of 62mm and 58mm, respectively. Mycelial growth was good in the order of strain No. 2, 10, and 9. The three selected strains, KNCAF-H-3, KNCAF-H-7 and KNCAF-H-2, were cultured in sawdust medium for 10 days and showed mycelial growth of 79mm, 76mm and 73mm respectively. The mycelial growth of the selected three cultivars was better than that of Greenpeace No 5, a control cultivar grown at 55mm.
