초록

모본 ASI 3305mut와 L5(3265-238701-2)-16을 2011년에 교잡하여, 2012년부터 2013년까지 생산력 검정시험을 통해 PM-L5(농진고)를 출원하였다. 농진고의 균사배양 최적온도는 $30^{\circ}C$이며, 버섯 발생온도는 $15{\sim}23^{\circ}C$로 중고온성이다. 자실체의 갓은 평반구형이며 색깔은 황갈색이고, 인피는 갓의 둘레에 생긴다. 버섯의 배양은 1.5kg 배지에서 최소 90~100일이 소요되며, 갈변이 다소 늦은 편이다. 버섯 발생형은 집중형이나 산조701에 비하여 초기 발생이 다소 늦으면서 개체수가 10개 내외이고, 주기별 발생이 고른 편이다. 톱밥 봉지재배 품종으로 지면 재배, 균상재배에서 모두 적합하다.

'Nongjin-go' is a new breed strain of Lentinula edodes, saw-dust bag variety. It is a cross combination of dikaryon Lentinula edodes ASI 3305mut and monokaryon L5-16 of L. edodes ASI 3305(Sanjo701ho). We crossbred them by 2011 and verified productive capacity from 2012 to 2013 in Rural Development Administration. Optimum temperature of mycelial growth is $30^{\circ}C$ and it of fruit-body primodium formation is range from 15 to $23^{\circ}C$. Nongjigo is agricultured at mid-high temperature well. Fruiting body is platy-hemisphere, light brown and centralizing. And bast is formed around edge of pileus. Yield productions per period is regular than 'Sanjo701'. Plastic bag culture medium is 1.5 kilogram and culture periods are 90~100 days. As its browning of pileus in culture is a little slow, Light and ventilation is needed a lot in light-culturing. Humidity is controlled properly for its color in fruit-body growing. Tested culture medium is consisted of 80% Oak-Tree saw-dust and 20% rice-bran.
