Abstract

White button mushroom (Agaricus bisporus) is the most widely consumed mushroom in the world, and domestic consumption is increasing owing to expansion of the westernized diet in recent years. Before 2000, most Korean mushroom farmers cultivated foreign varieties, but recently, Korean breeders are developing hybrid strains using molecular breeding tools. To produce a better mushroom cultivar, we evaluated some traits of button mushroom Agaricus bisporus strains. Mycelial growth rate at different culture temperatures was investigated by 25>20>15>30>$10^{\circ}C$. Recently developed domestic varieties had superior mycelial growth rate compared to the traditionally grown species. In particular, the ASI1338 strain showed excellent mycelial growth rate at different temperatures. Further, we confirmed that ASI1007, ASI1085, ASI1310, ASI1339 were strongly resistant to bacterial brown blotch, whereas ASI1053, ASI1103, ASI1140, ASI1146, ASI1177, ASI1183, ASI1195, ASI1321, ASI1331, ASI1336 were relatively weakly resistant. The average number of days for 16.5, and that for harvest was 5.7; the average yield was 142.7 g/2-kg bag. Mycelial growth rates at 10, 15, 20, $25^{\circ}C$ were similar, but that at $30^{\circ}C$ was lower. The mushroom yield was highly correlated with the number of days for pinheading and harvest.

양송이버섯(Agaricus bisporus)은 세계에서 가장 많이 소비되는 버섯이며, 서구화된 식습관의 확대로 인해 국내의 소비량도 최근 증가하고 있는 추세이다. 양송이버섯 품종은 2000년 이전에는 해외품종을 도입하여 사용하였으며, 최근 교잡에 의한 국산 품종의 개발이 시작되었다. 하지만 여전히 다른 버섯품목에 비해 품종의 수가 적은 실정이다. 배양온도별 균사생장속도는 25>20>15>30>$10^{\circ}C$ 순으로 균사생장이 우수한 것으로 확인되었으며, 최근 육성된 국내육성종들은 과거부터 수집된 종에 비해 균사생장이 우수한 그룹에 속하는 것을 확인할 수 있었다. 또한 ASI1338계통은 균사생장이 우수한 범위가 넓은 계통임을 확인 할 수 있었다. 세균성갈색무늬병 저항성 검증결과 ASI1007, ASI1085, ASI1310, ASI1339 저항성이 강한 계통이었으며, ASI1053, ASI1103, ASI1140, ASI1146, ASI1177, ASI1183, ASI1195, ASI1321, ASI1331, ASI1336 저항성이 상대적으로 약한 계통임을 확인할 수 있었다. 양송이버섯 수집자원의 평균 초발이 일수는 16.5일, 평균수확일수는 5.7일, 평균 수확량은 142.7 g/2 kg bag이었다. 각 특성들의 상관관계를 분석한 결과 균사생장속도는 10, 15, 20, $25^{\circ}C$는 서로 높은 상관성을 보이며 균사가 생장하였으나, $30^{\circ}C$에서는 다른 온도의 생장결과와 상관성이 낮아졌다. 수확량은 초발이일수, 수확일수와 상관관계가 높았다.
