갓과 대의 색택이 백색인 백색느타리 신품종『백선』의 주요특성은 다음과 같다. 균사생장적온은 28~31 o C이고 버섯발생온도는 22 o C, 버섯생육온도 20 o C로 ‘미소’보다 균사생장적온이 높으며 버섯발생 및 생육온도가 유사하며, 발생형은 다발형태를 나타내었다. 병재배시 배양기간은 30일, 초발이 소요일수는 4일, 생육일수는 4일로 총재배 기간은 38일이 소요되었다. 형태적 특성에 있어 갓직경은 32.5 mm, 대직경 9.1 mm, 대길이 91.4 mm로 ‘미소’에 비하여 가늘고 긴 형태를 나타내었으며, 갓색도(L)는 84.2, 대색도(L)은 83.4로 ‘미소’에 비하여 밝은 백색을 나타내었다. 수량은 생산력 검정시 1100 ml병에서 185 g을 나타내었으며, 농가실증재배시 A(평택) 184g/1100 ml, B(여주) 178 g/850 ml으로 대조품종 대비 40%이상 증수 되었다. 대의 물리성은 탄력성, 응집성, 씹음성, 깨짐성이 각각 80%, 57%, 720 g, 57 kg을 나타내었다. DNA다형성을 비 교 분석한 결과 UFPF1, UFPF3, UFPF4의 primer에서 교배모본인 ‘GMPO20410’와 ‘MGL2205’의 DNA의 밴드가 혼합되어 있었으며 품종 간, 균주 간의 밴드 차이가 있 었다. 저장기간에 따른 신선도는 4 o C에서 28일 저온저장 시 8점으로 신선한 상태였으며, 4 o C저장 후 상온보관 시 5점으로 식용 가능한 상태로 대조품종인 ‘미소’ 보다 저온 및 상온보관 시 신선도가 우수하였다.

Oyster mushrooms are an economically important crop, accounting for 35% of the total mushroom production in Korea. In this study, we developed a new cultivar of Pleurotus ostreatus, known as ‘Baekseon,’ which is characterized by a white pileus with a white stipe. It was bred by mating monokaryons isolated from white mutant oyster mushrooms that were naturally generated from ‘Gonji-7ho’ and ‘Wonhyeong-1ho’ at the Mushroom Research Institute, GARES, Korea in 2018. The optimum temperature for mycelial growth on potato dextrose agar medium was approximately 28-31 °C, and the optimum temperatures for primordia formation and growth of fruit bodies on sawdust media were 22 °C and 20 °C, respectively. The time required for the bottle-cultured mushrooms to complete spawn running, primordia formation, and growth of fruit bodies was 30 days, 4 days, and 4 days, respectively. The fruit bodies were bundle-shaped, the pilei were round type and white, and the stipes were white. The stipes were slender and longer than those of the control (‘Miso’). In the productivity test, the yield per bottle was 185 g/1100 mL, which was 45% greater than that of the control (‘Miso’). In the farm test, the yield per bottle for Farm A (Pyeongtaek) and Farm B (Yeoju) was 184 g/1100 mL and 178 g/850 mL, respectively. With regard to the physical properties of fruit bodies, the springiness, cohesiveness, gumminess, and brittleness of stipe tissue were 80%, 57%, 720 g, and 57 kg, respectively. These values were lower than those of the control (‘Miso’). To test the shelf life, the fruit bodies were wrapped with antifogging film and stored at 4 °C for 28 days and then at room temperature for 4 days; such conditions were sufficient for maintaining edibility.
