국내 재배비중이 가장 높은 큰느타리2호의 단점을 보완하고 버섯의 국내 육성품종 다양화하고 보급을 확대시키기 위해 육성한『곤지3호』의 주요 품종특성은 다음과 같다. 균사생장적온은 26~29℃, 버섯발생 및 생육적온은 14~18℃였으며, 배양일수 30일, 초발이소요일수 8일, 생육일수 5일로 전체 생육일수는 46일로 큰느타리2호와 대등하였다. 유효경수는 병당 2.4개, 대굵기 43.7mm, 대길이 123.8mm, 갓직경 64.9mm로 큰느타리2호와 비슷하였지만, 갓표면의 색도에 있어 명도값(L값)이 54.4로 큰느타리2호 58.2보다 낮아 전체 적으로 진회색을 나타내었다. 병당 수량 182g/1100cc 내외로 통계적 유의성은 없었으나 큰느타리2호 보다 높은 경향을 나 타내었다. 자실체의 단단한 정도(경도)는 7,790g/cm2 로 큰느타리2호 5,650g/cm2보다 높았고, 탄력성, 씹음성, 탄력성 등 전체적인 물리적 지표들이 큰느타리2호보다 높았다.
We bred a new strain of Pleurotus eryngii. It’s name is ‘Gongi No.3’ and it was bred by mating monokaryotic strain isolated from E08-5D2 and dikaryotic strain GMPE25016 from 2006 to 2010 in Mushroom Research Station, Gyonggi province A.R.E.S. The characteristics of a new strain ‘Gongi No.3’ is as follows ; The optimum temperature for mycelium growth was from 26 to 29 degrees celsius on PDA medium and those for the premodium formation and the growth of fruit body were from 14 to 18 degrees celsius. The period of spawn running was around 30days at 22 degrees celsius and the period taken from scratching old spawn to make premodium were 8 days. The color degree of cap surface was measured by color difference meter and that of a new strain ‘Gongi No.3’ was 54.4 by L-value. it was seem to be dark, compared with ‘Keunneutari No.2’. The hardness of fruit body of a new strain was higher than ‘Keunneutari No.2’. The yield was about 180g per bottle(1100cc). it was 10g more than ‘Keunneutari No.2’.
