Abstract

In order to breed new strains of oak mushroom, Lentinula edodes, on the sawdust cultivation, we collected 10 from Korea, Taiwan and China respectively and examined somatic incompatibility, morphological features of fruiting body and productivity. Four strains(SANJO701HO, FMRI2534, FMRI2337 and FMRI2613) shown remarkable results, were confirmed with parental strains. 80 monokaryotic strains derived from the selected 4 parental strains, were selected and 117 hybrid strains were made by mono-mono mating. Aslo, Physiological characteristics were investigated. Average of the mycelial growth of hybrid strains of mating combination SANJO701HO-FMRI2337 was approximately 10% lower than other mating combinations. Overall, This study was founded to develop new varieties of L. edodes. The productivity of new 117 strains on sawdust cultivation needs continued research.

표고(Lentinula edodes)는 우리나라의 주요 임산버섯으로 최근 표고 톱밥재배가 정착됨에 따라 급속도로 확산되고 있으나 국내 환경에 적합하고 재배시기를 다변화 할 수 있는 균주의 육성이 시급하다. 따라서 9개의 균주를 시험재배하여 생산성이 높고 자실체 특성이 우수한 4개 균주(SANJO701HO, FMRI2534, FMRI2337, FMRI2613)를 모균주로 선발하였고 균주당 각각 20개씩 총 80개의 단핵균주를 분리하여 117개의 교배균주를 육성하였다. 그중 산조701호와 FMRI2337의 교배조합이 다른 조합의 교배균주들보다 평균생장속도가 10% 가량 낮았으며 이들 교배균주의 배양 및 생리적 특성을 비교 조사하였다. 따라서 본 연구는 우수한 톱밥재배용 품종개발의 기반조성을 마련하고자 하였으며, 차후 교배균주에 대한 생산성 검정의 연구가 필요하다.
