Abstract

A new cultivar of oak mushroom Lentinula edodes 'Jadam' was bred from monokaryotic strains of 'Hwadam-18' and 'GMLE36295-22'. The optimum temperature for mycelial growth of 'Jadam' on potato dextrose agar was 22-25℃. Total cultivation period of the new cultivar, from inoculation to its first harvest, was 122-124 days, shorter to that of the control cultivar 'Hwadam'. Total yield of 'Jadam' was 623.8 g per 3 kg substrate, and is higher than that of 'Hwadam' (455.2 g). In the fruiting body of the new cultivar, the stipe was shorter and thinner than those of 'Hwadam'. A farmhouse field test showed that the period of mycelial growth and browning was shorter than that of control cultivar 'L808'. The total yield for 2 flush was 543.3 g for 'Jadam'. It was similar to the 585.3 g of the control cultivar. Therefore, the new cultivar 'Jadam' could be a substitute for 'L808' in the field of farms.

국내 톱밥재배용 우수 품종을 육성하기 위해 기존의 육성품종과 수집 우수계통으로부터 단포자 교배를 통해 육성한 '자담'의 주요 특성은 다음과 같았다. 균사생장 적온은 22-25℃, 발이 및 생육온도는 13-20℃이었으며, 자실체 형태는 '평반구형', 발생형태는 '산발형'으로 나타났다. '자담'은 배양기간 25일, 갈변기간 86일, 발이기간 4일, 생육기간 7-9일로 첫주기 버섯 수확까지 총122-124일 소요되었고, 대조품종보다 발이기간이 2일 짧았다. '자담'의 3주기 평균 개체중은 44.6 g으로 대조품종과 유사하였고, 평균 유효개체수가 대조품종 보다 2.1개 많아 총수량이 623.8 g으로 대조품종(455.2 g)대비 약 37% 높은 수량을 보였다. '자담'의 자실체는 대조품종 대비 갓 두께는 유사하였으나, 대의 길이와 굵기가 작았다. 실증 결과, '자담'은 배양기간 26일, 갈변기간 84일로 대조품종(L808)에 비해 배양기간이 10일 짧았으며 2주기 총수량이 543.3 g으로 대조품종과 유사한 결과를 보였다.
