Abstract
The 'Heuktari', a new mid-high temperature adaptable variety of oyster mushroom for the bottle culture, was bred by mating with monokaryons isolated from 'P11056' and 'MT07156'. The optimum temperature for the mycelial growth was $23{\sim}26^{\circ}C$ on PDA medium and that for the primordia formation and the growth of fruiting body of 'Heuktari' was $18{\sim}19^{\circ}C$ on sawdust substrate. In case of bottle cultivation, the period of mycelial growth was required about 30 days. In addition, the period of primordia formation and growth of fruiting body was 4 days and 5 days, respectively. In the characteristics of fruiting body, shape and color of pilei were round type and dark grayish brown, stipe color was white color and stipe shape was short and thick. The yield of fruiting bodies was 180 g/900 ml bottle which was 15% higher than that of Suhan-1ho. The gumminess and brittleness of stipe tissue were 110% and 140% stronger than those of Suhan-1ho, respectively.
갓색이 진한 중고온성 병재배용 고품질버섯 '흑타리'의 주요특성은 다음과 같다. 균사생장적온은 $23{\sim}26^{\circ}C$이고 버섯발생 및 생육온도는 각각 $18{\sim}19^{\circ}C$로 중고온성을 나타내었다. 병재배시 배양기간은 30일, 초발이 소요일수는 4일, 생육일수는 5일로 총재배기간은 39일이 소요되었다. 갓크기는 35.2 mm이며, 갓색은 진회갈색을 나타냈다. 대직경 11.4 mm, 대길이 84.2 mm로 굵고 짧은형태이며, 대색은 백색을 나타내었다. 수량은 생산력검정시 900 cc병에서 180 g을 나타내었으며, 농가실증재배시 광주 226 g/1100cc, 양평 188 g/900 cc, 여주 241 g/1100 cc의 수량을 나타내었다. 대의 물리성에서 있어 탄력성, 응집성, 씹읍성, 깨집성이 각각 96%, 82%, 511g, 47 kg을 나타내었다. DNA다형성을 비교 분석한 결과 UFPF2, UFPF3, UFPF4등의 primer에서 교배모본인 'P11056'와 'MT07156'의 DNA의 밴드가 혼합되어 있었으며 품종간, 균주간의 밴드 차이가 있었다.
