초록

본 연구는 농촌진흥청에서 육성한 백승과 국외 수집자원(KMCC02260)을 모본으로 하여 단핵균주를 분리 후 mon-mon교잡을 통해 '백운' 품종을 육성하였다. 균사배양 특성은 25℃에서 두 품종의 균사생장이 가장 좋았으며 15, 25℃에서 백운의 균사생장 속도가 대조품종보다 더 빨랐으며 배지별 시험에서도 모든 배지에서 백운의 균사생장이 우수하였다. 톱밥 병에 접종 후 균사 배양기간은 백운이 2일, 초발이일수도 1일 더 빨라 전체적인 생육기간을 단축시켰으며 수량은 228.0±10.9 g/병(850 ml)으로 대조품종 대비 8.3% 증수하였다. 백운의 형태적인 특성은 갓이 크고 대가 굵으며 갓이 순백색이었다. 대치배양과 유전적 다형성 검정 결과, 백운이 두 모본과 대조품종과 유전적으로 다르다는 것을 확인하였다.

Flammulina velutipesis a popular edible mushroom in South Korea, accounting for approximately 30% of the total mushroom export in the country. Despite its significant position in the domestic mushroom industry, approximately 65% of the cultivated F. velutipes are foreign varieties. To secure variety rights and enhance competitiveness in the export market, there is a need to develop domestic varieties with stable production and excellent shelf life. We focused on breeding a new variety called 'Baekwoon' through mon-mon crossing, using 'Baekseung' and an international collection strain (KMCC02260) as parents. Baekwoon exhibited faster mycelial growth rates at 15 ℃ and 25 ℃ and higher mycelial growth across four tested media compared to that of the control variety. Under bottle cultivation, Baekwoon had a mycelial cultivation period that was shorter by approximately 2 days compared to that of the control. The yield of Baekwoon was 228.0±10.9 g, 8.3% more than that of the control. Furthermore, Baekwoon displayed distinct morphological features characterized by a larger pileus and thicker stipe compared to that of the control variety. Genetic tests confirmed that Baekwoon is genetically different from both parental strains and the control variety. It is expected that the newly developed F. velutipes variety, Baekwoon, will be evaluated for its adaptation in different regions and actively promoted in the field, ultimately increasing the market share of domestic varieties.
