Abstract

In this study, a new strain of Lentinula edodes (Shiitake) Poongnyunko was bred from dikaryotic KFRI 490 and monokaryotic KFRI 536 by Di-mon crossing method. In this study, the productivity was conducted through bed-log and sawdust substrate cultivation. The Poongnyunko showed significant intensive production from summer to autumn. Optimum temperatures of fruit-body formation were $17{\sim}24^{\circ}C$. The total amount of fruit-body production during 4 years by bed-log cultivation was $22kg/m^3$, and total yield of fruit-body until the 3rd flush was 648 g/ 2 kg. In case of sawdust substrate cultivation, the mycelial incubation period was 110~130 days. The suitable temperature and relative humidity were $18{\pm}1^{\circ}C$ and $90{\pm}5%$ respectively.

본 연구에서는 KFRI 490의 2핵균사와 KFR 536의 1핵균사를 Di-mon 교잡을 시도하여 새로운 품종 풍년고를 개발하였다. 이 실험에서는 원목재배와 톱밥재배 실험을 통하여 생산성 및 재배적 특성을 파악하고자 하였다. 풍년고의 발생유형은 여름, 가을의 하추형(夏秋型)으로 집중발생 한다. 최적 발생 온도는 $17{\sim}24^{\circ}C$로 고온재배에 적합하다. 원목에서 건중량 $22kg/m^3$, 톱밥재배에서 3차 발생까지 649 g/2 kg으로 원목 및 톱밥의 겸용 재배가 기능함을 알 수 있었다. 톱밥재배의 배양기간은 110~130일이다. 공조시설의 발생온도 $18{\pm}1^{\circ}C$, 습도 $90{\pm}5%$에서 버섯을 가장 많이 발생시켰다.
