Abstract
To develop new variety of oyster mushroom, 63 intra-specific hybrids between the strain Suhan and #Nongi201 were developed using hyphal anastomosis technique in 2004. The Po2008-275 hybrid between the dikaryon strain 04-154(Suhan x #Nongi201) and the monokaryon strain derived from ASI2487 were developed using hyphal anastomosis in 2008. The Po2008-275 was shown the best cultural characteristics, selected to be a new variety and named as 'Guseol'. The new commercial strain, 'Guseol' had dark grey pilei and grows well under spring and autumn conditions in Korea. The fruiting bodies of 'Guseol' were of an excellent quality in that not only the stipe was thick and long but also the pileus was small and hard. The optimum temperatures for mycelial growth and fruiting body development were
느타리 버섯류의 새로운 품종을 개발하기 위하여 고품질의 짙은 회색느타리 신품종을 육성하였다. 2003년부터 2004년까지 느타리 유전자원의 특성검정을 하였다. 2008년에 육종모본수한과 '농기201호'의 단핵체간 교잡하여 04-154 교잡주를 육성하였다. 이 교잡주 04-154와 품종 '청풍'의 단핵체와 다시 교잡하여 우수한 Po2008-275를 선발하여 특성검정, 확대재배를 실시하여 농작물 직무육성 신품종 선정심의회에서 '구슬'로 명명되었다. 주요특성으로 균사 생장 적온이
