Abstract

This study was conducted to diversify the cultivation of mushroom items and develop a competitive variety of Hypsizigus marmoreus. We focused on developing Hypsizigus marmoreus with lower bitterness, likable shape, and high yield. We have collected and tested characteristics of genetic resources from domestic and abroad since 2019. Breeding (2019), characterization (2020), productivity test (2021), and farm demonstration test (2021) have been sequentially conducted. We bred the new variety 'Yunseul' with unique traits. The optimal temperature for mycelial and fruit body growth were 22-25℃ and 15-18℃, respectively. It was similar to the control variety (Mangadak-2Ho) in the pileus form (hemispherical shape) and the cultivation period. However, it was thinner and longer than the control variety with the pileus diameter, thickness, stipe diameter, and length being 19.9 mm, 7.0 mm, 9.4 mm, and 86.3 mm, respectively. The effective number of fruit bodies was 47.8 in bottle cultivation, which was more than that of the control variety. The yield was 197.4 g/bottle (1,100 cc), which was 30% higher than the yield of the control variety, 151.9 g/bottle (1,100 cc). The parent and control varieties were also incubated alongside the new variety. The somatic incompatibility line was distinct. The band pattern in the mycelial DNA PCR reaction was different from that of the parent and control varieties, confirming the hybrid species.

버섯재배 품목 다양화를 위하여 경쟁력 있는 품목을 개발하고자 쓴 맛이 적고, 자실체의 형태와 품질, 생산성이 우수한 느티만가닥버섯을 육성하였다. 2019년부터 국내외에서 유전자원을 수집하고 교배하여, 특성검정 및 생산력 검정, 농가실증의 과정을 거친 느티만가닥버섯 신품종 '윤슬'의 주요 특성은 다음과 같다. 균사생장적온은 22~25℃, 발이 및 생육온도는 15~18℃, 재배일수는 113일로 대조품종(만가닥2호)과 유사하였다. 갓 색은 회갈색으로 대조품종(갈색)에 비해 더 밝고, 갓 무늬는 대조품종에 비해 잘게 나타났다. 갓 형태는 반구형으로 대조품종과 유사하였다. 대 직경과 길이가 각각 9.4 mm, 86.3 mm 였으며, 대조품종(10.2 mm, 79.9 mm)에 비해 가늘고 긴 형태로 대 밑부분까지 직경이 일정한 원통형으로 나타났다. 자실체 병 당 유효경수는 1,100 cc(?75 mm)병 기준으로 47.8개로 대조품종 (31.0개)보다 더 많았다. 병 당 수량은 1,100 cc(?75 mm)병 기준으로 197.4 g으로 대조품종(151.9 g)대비 약 30% 높았다. 식미평가 결과 쓴 맛 정도는 5점척도 기준으로 2.3으로 대조품종(4.1)에 비해 쓴맛이 덜했다. 모본 및 대조품종과 대치배양 시 대치선이 뚜렷하고, 균사체 DNA PCR반응 결과, 밴드패턴이 모본 및 대조품종과 다른 양상을 보여 교배종임을 확인하였다. 느티만가닥버섯은 국내도입 후 적지않은 시간이 흘렀으나 여전히 다른 버섯품목에 비해 시장의 규모가 작다. 실질적인 농가보급 확대 및 소비촉진을 위한 관심과 연구가 이어져야 할 것으로 사료된다.
