Abstract

A new dark brown variety of Flammulina velutipes, referred to as 'Asakchoco', was bred by crossing two monokaryons isolated from the 'Yeoreumhyang2ho' and 'Guemhyang2ho' varieties. The pileus color of the new variety is dark brown and the stipe color is ivory, with uniformity from the upper section to the base. In addition, the primordia formation is uniform compared to that of the control, and the advantage of this is that the pileus does not become deformed after the primordia formation. During bottle cultivation, the period necessary for mycelial growth was 40 d, for primordia formation was 8 d, and for fruiting body growth was 16 d. The total cultivation period was 64 d, which was 2 d shorter than that of the control. The pileus was smaller and thicker and the stipe diameter was the same, but the stipe length was longer than that of the control. The number of valid stipes per bottle was 441, 24% higher than that of the control (357), and the yield was 197 g, 19% higher than that of the control (166 g).

팽이버섯 신품종 '아삭초코'는 충청북도농업기술원 육성품종 '여름향2호'와 '금향2호'로부터 분리한 단포자를 교배함으로써 육성된 품종으로, 갓 색은 진한 갈색을 나타내며 대 색은 미색으로 대 상부에서 기부까지 색이 균일하다. 또한 대조품종 '여름향2호' 대비 발이가 매우 균일하며 발이 후 갓이 기형적으로 커지는 현상이 없는 것이 장점이다. 병재배 시 배양기간은 40일, 초발이 소요일수는 8일, 생육일수는 16일로 총재배기간이 64일이 소요되어 대조품종 '여름향2호'에 비해 2일이 단축되었다. 갓직경 9.0 mm, 갓두께 4.7 mm 으로 대조품종에 비해 갓직경은 작고, 두께는 두꺼웠으며, 대직경은 2.9 mm로 대조품종과 같았으나 대길이는 102.5 mm로 대조품종 대비 길게 나타났다. 1,100 ml(Ø75) 병당 유효경수는 441 개로 대조품종 357 개 대비 24% 많았으며, 병당 평균수량은 197 g으로 대조품종 166 g 대비 19% 높게 나타났다.
