큰느타리버섯 신품종 '새곤지' 육성 및 특성

Abstract

큰느타리버섯의 품종다양화와 보급확대를 목적으로 발생개체수가 적고 생력재배에 적합한 "새곤지"의 특성을 조사한 결과는 다음과 같다. 균사생장을 위한 적정온도범위는 <TEX>$23{\sim}26^{\circ}C$</TEX>로 대조품종 <TEX>$26{\sim}29^{\circ}C$</TEX>보다 낮았다. 자실체 발생 및 생육적온은 <TEX>$15{\pm}1^{\circ}C$</TEX>였으며, 재배기간은 51일로 대조품종과 동일하였다. 갓형태는 생육초기 반반구형에서 생육후기까지 평반구형의 갓형태를 유지하였다. 병당 발생개체수는 3.5개로, 대조품종 12.8개 대비 9.3개 적었다. 대길이는 135.8 mm로 대조품종 124.6 mm보다 길었고, 갓표면의 색도(Lightness)는 60.4로 대조품종 57.6보다 높아 연회색을 나타내었다. 탄력성과 응집성은 대등하였고, 깨짐성, 경도값은 각각 71,068 g, <TEX>$5,662g/cm^2$</TEX>으로 대조품종보다 낮았다. 병당수량은 900 cc/<TEX>$65{\Phi}$</TEX> 병에서 106.4 g, 1100 cc/<TEX>$75{\Phi}$</TEX> 병에서159 g으로 대조품종 과 대등하였다. We bred a new strain of Pleurotus eryngii having few number of fruit body per bottle. It's name is 'Saegonji' and it was bred by mating monokaryotic strain isolated from E12-176 and monokaryotic strain 'aerini No.3' in Mushroom Research Institute, Gyonggi province A.R.E.S. The characteristics of a new strain 'Saegonji' are as follows. The optimum temperature for mycelium growth was from 23 to <TEX>$26^{\circ}C$</TEX> on PDA medium and those for the primodium formation and the growth of fruit body were about <TEX>$15^{\circ}C$</TEX>. The period from spawn innoculation to harvesting required around 51 days at <TEX>$20^{\circ}C$</TEX>. The number of fruit body per bottle was 12.8 and it was 9.3 less than 'Keunneutari No.2'. The length was 135.8 mm. It was longer than 'Keunneutari No.2', The color of cap was white grey, while that of 'Keunneutari No.2' was grey. The yield was about 159 g per bottle(1100cc) and it was same as Keunneutari No.2.
