Abstract

Recently, with the increasing global demand for Ganoderma lucidum as a material for functional beverages, varieties with enhanced functionality are needed. As part of this effort, 10 strains were selected from a collection of 160 G. lucidum strains, based on their quantity and fruiting body characteristics. These included four strains collected in Korea, three in Japan, and three of unknown origin. Approximately 44% of the 1,290 hybrid strains were secured. After two rounds of bag cultivation in oak sawdust, three strains (G-20-4, G-20-5, and G-20-7) were ultimately selected for single-timbered cultivation. Among these, G-20-4 demonstrated the earliest harvesting with a large size and a bright cap. Additionally, this strain exhibited the highest levels of total glucan, β-glucan, total triterpenoid, total polyphenol, and total flavonoid content.

최근 전 세계적으로 기능성 음료 소재로 영지버섯의 수요가 높아짐에 따라 기능성이 강화된 품종 개발이 필요한 시점이다. 이에 따라 수집한 영지버섯 160균주 중 수량성과 자실체 특성을 통해 한국에서 채집한 균주 4점, 일본 3, 불명 3점으로 총 10점을 선발하고 선발한 모균주를 대상으로 원형질체 유래 단핵균주를 이용하여 약 44%로 1,290점의 교잡주과 확보되었다. 이들을 참나무 톱밥 봉지재배 2회 재배로 최종적으로 G-20-4, 5, 7의 3계통을 선발하여 단목재배를 진행하였다. 그 결과 G-20-4가 가장 빨리 수확되며, 개체수가 많고 갓이 밝았다. 또한, 총 glucan, β-glucan, 총 triterpenoid, polyphenol, flavonoid 함량이 가장 많았다.
