Abstract

A new spore-less cultivar Lentinula edodes 'Daedam' was bred from monokaryotic strains of 'LE15401-24' and 'LE192118-10'. The optimum temperature for mycelial growth of 'Daedam' on potato dextrose agar was 22~25℃. Total cultivation period of the new cultivar, from inoculation to its first harvest, was 134 days, similar to that of the control cultivar 'Hwadam'. Total yield of 'Daedam' was 222g per 3kg substrate, and was lower than that of control cultivar(266.0g). The fruiting body of 'Daedam' had a thick and small pileus and a longer stem compare to control cultivar. As a result of a analyzing the productivity of 'Daedam' on the different substrate types, the biological efficiency was 26.7% in the 1.2kg cylindrical substrate(CS), which was higher than that of the 3kg rod-type substrate(RS). 'Daedam' had a similar yield compared to 'Hanacham' in first fruiting body production, but the cultivation period was 40 days shorter. Therefore, 'Daedam' can only harvest fruiting bodies once, it is thought that it can be used as spore-less oak mushroom cultivar for short-term cultivation instead of 'Hanacham' in mushroom farms.

표고 톱밥재배용 무포자 품종의 육성을 위해 수집균주 중 우량계통의 단포자 교배를 통해 육성된 '대담'의 주요 특성은 다음과 같다. '대담'의 균사생장 적온은 22~.25℃, 발이 및 생육온도는 16~18℃이었으며, 자실체 형태는 평반구형이며 갓을 형성하지 않는 무포자품종이다. '대담'은 배양기간이 21일, 갈변기간 96일로 대조품종('화담')과 유사하였고, 발이기간은 5일, 생육기간은 9일로 전체 재배기간은 134일로 같았다. '대담'의 개체중은 32.4g으로 대조품종과 유사하였고, 유효개체수는 6.8개로 대조품종 보다 1.3개 낮았으며, 총수량은 222g으로 대조품종의 266g에 비해 낮았다. '대담'의 자실체는 대조품종 대비 갓이 두껍고, 갓 직경은 다소 작았으며, 대의 굵기는 작고 긴 특성을 보였다. '대담'의 배지형태별 생산성 분석결과, 1.2kg 원통형 배지에서 생물학적 효율이 26.7%로 3kg 봉형배지보다 높았으며, '하나참'와 비교 시 재배기간이 40일 짧고 수량도 유사하여, 단기 재배용 품종으로 활용이 가능할 것으로 생각된다.
