Abstract

A new cultivar of oak mushroom 'Dadam' was bred from monokaryotic strains of 'GMLE36062-4' and 'GMLE36288-34'. The optimum temperature for mycelial growth of the new cultivar 'Dadam' on potato dextrose agar was 19-22℃. Total cultivation period of the new cultivar, from innoculation to its first harvest, was 135-139 days, similar to that of the control cultivar 'Hwadam'. The pileus color and stipe thickness of the new cultivar were darker and thinner than those of 'Hwadam'. Total yield of 'Dadam' was 621 g per 3 kg substrate, and is higher than that of 'Hwadam' (371 g). In farmhouse field test, it showed that the period of mycelial growth, browning, and fruiting body formation were the same as those of the control cultivar L808. The number of available fruiting bodies of 'Dadam' was 15, and is lower than that of the control (47), therefore, it was possible to save workforce in thinning. The total yield for 2 flush was 480 g for 'Dadam', similar to the 473 g of the control cultivar.

표고 톱밥재배용 다수성 품종 육성을 위해 수집균주 중 우량계통의 단포자 교배로 육성한 '다담'의 주요 특성은 다음과 같다. '다담'의 균사생장 적온은 19~22℃, 발이 및 생육온도는 13~20℃, 발생형은 산발형으로 대조품종 '화담'과 유사하였고, 형태는 평편형으로 평반구형인 '화담' 차이가 있었다. 또한, 자실체 갓색은 '화담' 보다 진하고, 갓두께는 얇고, 대길이는 긴 특성을 가졌다. '다담'의 총 재배기간은 135~139일로 '화담'의 138~142과 크게 차이 나지 않았다. '다담'의 3주기까지 수량은 621 g으로 '화담' 371 g 보다 67% 많았다. 주기별 수량 양상을 보면, '다담'과 '화담' 모두 3주기 수량의 80~83%를 2주기 동안 수확할 수 있었다. 특히, '다담'은 1주기 수량비중이 60%로 '화담' 52%보다 1주기에 수량이 집중되는 특성을 보였다. 농가실증시험 결과, '다담'은 농가재배 품종인 'L808' 보다 다소 갓크기는 작고 대길이가 길었고 재배기간과 수량은 큰 차이 없었다. '다담'의 발생한 자실체 개체는 1개 배지에 평균 15개로 'L808'의 47개에 비해 약 3배정도 적어 솎기에 투입되는 노동력을 절감하는 효과가 기대된다.
