Abstract
This study was conducted to reduce the phenomenon of the biased cultivation of certain mushroom varieties and to develop a competitive variety of Grifola frondosa. We developed the first Korean white commercial mushroom strain, 'Bakyeon', by crossing monokaryons derived from brown strains. We have collected and tested the characteristics of mushrooms from domestic and international genetic resources since 2018. We bred the unique domestic variety, 'Bakyeon', which has the following characteristics. The optimal temperature for mycelial growth was 25~28℃ and the optimal temperature for fruit body growth was 16~18℃. The new variety was similar to the control variety (Daebak) in terms of the pileus, which formed a pine cone shape, and the number of days of cultivation. The yield was 94.1 g/bottle, which was 23% lower than the 108.5 g/bottle yield of the control variety. When incubating the parent and control varieties, the replacement line was clear. Moreover, polymerase chain reaction analysis of mycelial DNA resulted in different band patterns between the parent and control varieties, confirming the hybrid species.
국내 버섯품목의 편중재배를 해소하고 새로운 소득원 개발을 위해 발이가 안정적인 백색 잎새버섯 품종을 육성하고자 하였다. 국내 최초로 육성한 백색 잎새버섯 '백연'의 주요 특성은 다음과 같다. 균사생장적온은 25~28℃, 발이 및 생육온도는 16~18℃, 재배일수는 77.2일(병재배), 80.0일(봉지재배)로 대조품종(대박)과 유사하였다. 자실체 갓은 대조품종 '대박' 비해 갓 크기가 작고 두께가 얇았다. 자실체 직경과 높이는 대조품종에 비해 직경이 작고 높이가 길었다. 병당 수량은 94 g으로 '대박' 109 g 보다 23% 적었고, 봉지당 수량은 121 g으로 '대박' 177 g 보다 32% 적어 수량성이 낮았다. 낮은 수량을 해결하기 위해서는 품종에 적합한 배지개발 등 재배기술과 육종모본으로 활용하여 수량이 높은 백색 품종개발에 대한 연구가 필요하다.
