초록

버들송이의 기존품종의 단점을 보완하고 품종 다양화를 위해, 단포자 교잡에 의해 육성된 '참'의 주요특성은 다음과 같다. 균사 생장적온은 $26{\sim}28^{\circ}C$로 '버들송이1호'보다 다소 높았고 버섯발생 및 생육온도는 $18{\sim}20^{\circ}C$로 '버들송이1호'와 같았으며, 톱밥+밀기울+미강+건비지(70:10:10:10, v/v)배지에서 재배 시, 배양온도 $22{\sim}23^{\circ}C$에서 배양일수는 38일 내외, 생육 온도 $18{\sim}20^{\circ}C$에서 발이 일수는 7일, 자실체 생육일수는 5일로, 재배일수는 50일이 되어 '버들송이1호'와 비슷하였다. 자실체는 개체형으로 발생하고 갓 형태는 반반구형으로 '버들송이1호'와 같았으나 갓 색은 갈색으로 '버들송이1호'보다 짙고 갓 두께가 '버들송이1호'보다 두꺼웠으며, 대는 '버들송이1호'보다 굵고 길었다. 병 발생에 있어서 PDA평판배지에 '참'과 병원균을 대치배양 시 Trichoderma virens와 Trichoderma harzianum에 대해서 '버들송이1호'와 같이 저항성이 약했으며, 포장재배시험에서도 배양과정에서 푸른곰팡이병(Trichoderma spp.)이 4.8~5.0%로 '버들송이1호'와 비슷하였다. 수량은 $850m{\ell}$병(${\phi}$58 mm)당 141 g으로 '버들송이1호'와 통계적 유의차가 없었으며, 물리성에서 갓의 강도 및 취성이 '버들송이1호'보다 높았고, 저장성에서 $4^{\circ}C$ 저장 시 판매가능기간으로 볼 때 10일로 '버들송이1호'보다 2일 길었다.

'Cham', a new cultivar of Agrocybe aegerita, was bred by crossing between monokaryotic strains isolated from GMAG45021 and 'Beodeulsongi1ho' in Mushroom Research Station, Gyonggi Province A.R.E.S. in 2007. The optimum temperature for the mycelial growth of 'Cham' was 26 to $28^{\circ}C$ on PDA medium, whereas that of 'Beodeulsongi1ho'(control) was 24 to $26^{\circ}C$. The optimum temperature for the primordial formation and fruiting body development of 'Cham', as well as 'Beodeulsongi1ho', was 18 to $20^{\circ}C$. In the bottle cultivation, the spawn run period of 'Cham' at 22 to $23^{\circ}C$ was around 38 days and the period from scratching of inoculum to harvest was 12 days. These characteristics of 'Cham' were not different from those of 'Beodeulsongi1ho'. However, 'Cham' had more dark brown-colored, and thicker and stronger pileus, and longer and thicker stipe compared to that of 'Beodeulsongilho'. Freshness of 'Cham' was maintained for 10 days at the storage temperature of $4^{\circ}C$, while that of 'Beodeulsongi1ho' was maintained for 8 days. Moreover, the yield of fruiting bodies of 'Cham' was $141g/850m{\ell}$ bottle, which was similar to that of 'Beodeulsongi1ho'. Both 'Cham' and 'Beodeulsongilho' have lower resistivity against Trichoderma virens and Trichoderma harzianum.
