Abstract

Wild Lentinula edodes (shiitake) strains are an important breeding material for developing new varieties suitable for various consumer preferences and environmental conditions. The morphological characteristics of 100 wild shiitake strains collected from 14 regions were investigated in a sawdust block cultivation. The characteristics of their fruiting bodies were diverse. Among them, 38% of the caps was convex, 33% was broadly umbonate, 27% was applanate, and 2% was shallowly depressed. In terms of their stipes, 55, 23, and 22% were the column, clavate, and funnel type, respectively. The shape of the cap was the most diverse on Mt. Hwaak, whereas the shape of the stipe showed various phenotypes from various regions. Even among strains collected from the same forest, different types of mushrooms were observed. In conclusion, wild shiitake strains that have adapted to various environmental stress can be used to develop new varieties. Thus, securing various genetic resources and studying their traits are important for researching breeding technology.

다양한 소비자의 선호도와 환경에 적합한 새로운 품종을 개발하는데에 야생표고버섯은 중요한 육종 소재이다. 14개의 지역에서 채집한 총 100개의 야생 표고 균주들의 사각블럭 톱밥배지 재배 환경내에서 자실체의 형태적 특성을 조사하였다. 각 지역에서 채집한 균주들의 형태는 다양하게 나타났다. 전체 균주들 중에서 갓 종단면은 평반구형 38%, 중앙볼록형 33%, 편편형 27%, 중앙오목형 2%가 나타났으며, 대의 형태는 기둥형 55%, 곤봉형 23%, 깔때기형 22%가 확인되었다. 갓의 형태는 화악산에서 가장 다양하게 나타났으며, 대의 형태는 여러 지역의 균주에서 다양한 표현형을 나타내었다. 동일한 산림에서 채집된 균주들 사이에서도 각각 다른 형태의 버섯이 관찰되었다. 다양한 환경에서 적응한 야생 표고 균주들은 스트레스에 대한 적응력이 향상된 품종을 개발하는 자원으로 활용될 수 다. 또한 다양한 유전자원의 확보와 형질을 연구하는 것은 새로운 육종품종을 개발하는데 자산이라고 생각한다.
