Abstract

Flammulina velutipes is the representative edible mushroom in Korea. It makes up around 18% of the total mushroom production and accounts for about 36% of the total mushroom export. Despite being one of the most industrially important mushroom in Korea, the distribution rate of domestic cultivar was low (~31.6%) in 2020. Therefore, we need a new domestic cultivar with high quality as the main export mushroom. We developed a new white domestic cultivar, 'Seolhan', bred by mating two monokaryotic strains isolated from Baekseung and Woori-1ho. The optimum mycelial growth temperature was 25℃ and Seolhan had higher mycelial growth than the control at 20 and 25℃. In bottle cultivation, the optimum temperature of incubation was from 15℃ to 17℃ and the growth temperature of Seolhan was 7-8℃, which was slightly higher than that of the control. The yield of Seolan was 226.5±8.0 g, an increase of 18.4% compared to the control. The period of primodia formation also was a couple of days ahead. In morphological traits, the pileus of Seolhan was smaller than that of the control, the stipe was thicker, and the color brighter. As the results of replacement culture and genetic diversity test, it was confirmed that Seolhan was genetically different from other white varieties.

팽이(Flammulina velutipes)는 주름버섯목(Agaricales), 뽕나무버섯과(Physalacriaceae)에 속하는 담자균류로서, 국내 생산량은 연간 31,818톤('19)으로 전체 생산량의 약 18%이며 버섯 전체 수출액의 약 36%를 차지할 정도로 대표적인 식용버섯이다. 그러나 국내 재배되고 있는 팽이 국산품종의 비중이 31.6%(20')로 매우 낮으므로 국제 경쟁력이 우수한 국내육성 품종확보가 필요하며 수출 버섯으로서 보다 품질이 우수한 품종 육성이 필요하다. 이에 본 연구는 농진청에서 육성한 '백승'과 '우리1호'의 단핵균주를 확보하여 mon-mon교잡을 통해 '설한' 품종을 육성하였다. 균사배양 특성은 25℃에서 균사생장이 가장 좋았으며 20, 25℃에서 대조품종보다 균사 생장속도가 빨랐다. 병재배 시 배양 최적온도는 15~17℃로 배지온도가 20℃이상 되지 않게 관리해야하며 생육온도는 7~8℃로 대조품종에 비해 다소 높다. 또한 자실체 수량은 병당(850 mL) 226.5±8.0 g으로 대조품종에 비해 18.4% 증수하였으며 초발이일수가 2일 빨라 전체적인 생육기간이 단축되었다. 또한 설한의 외형은 대조품종보다 갓이 작고 대는 굵었으며 갓 색이 더 밝았다. 대치배양과 유전적 다형성 검정 결과, 설한이 다른 흰색 품종들과 유전적으로 구별되는 것을 확인하였다.
