고온성 연갈색 팽이버섯 신품종 '여름향1호'의 육성 및 특성

Characteristics and breeding of 'Yeoreumhyang1ho': a new light brown variety of Flammulina velutipes adaptable to high temperature

Abstract

팽이버섯 신품종'여름향1호'는 '갈뫼'와 '건국1호'로부터 분리한 단포자를 교배함으로써 육성된 품종으로, 갓색이 연한 갈색을 나타내며, 고온성이면서 재배기간이 짧은 장점이 있다. $16^{\circ}C$ 고온에서 병재배 시 배양 기간은 22일, 초발이 소요일수는 6일, 생육일수는 10일로 총재배 기간이 38일이 소요되어 대조품종 '금향'에 비해 3일, '갈뫼'에 비해 7일이 단축되었다. 특히 버섯 발생이 빠르면서도 균일성이 우수하였으며, 갓 색은 진한 미색인 '금향'과 중간 갈색인 '갈뫼'의 중간 수준인 연한 갈색을 띠었다. 수량은 850 ml(Ø59) 병 당 138 g으로 '금향' 대비 10% 증수되었다.

'Yeoreumhyang1ho' - a new variety of Flammulina velutipes, light brown in color and adaptable to high temperature - was bred by mating two monokaryons isolated from 'Garlmoe' and 'Konkuk1ho'. It exhibited better quality compared to 'Geumhyang' and 'Garlmoe' under conditions where temperature was maintained at $16^{\circ}C$, without exposure to low temperature ($4^{\circ}C$), during the cultivation period. Bottle cultivation at $16^{\circ}C$ required 22, 6, and 10 days for mycelial growth, primordia formation, and growth of the fruit body, respectively. The total cultivation period for 'Yeoreumhyang1ho' was observed to be 38 days, which is 3 and 7 days shorter than that for 'Geumhyang' and 'Garlmoe', respectively. The primordia formation showed remarkable uniformity and the pileus color was observed to be light brown, an intermediate between yellowish ivory of 'Geumhyang' and medium brown of 'Garlmoe'. The yield was 138 g per 850 ml bottle, which was 10% higher than that of 'Geumhyang'.
