Abstract

Esterase isozyme band patterns were compared between the wild strain and commercial strain of Flammulina velutipes. Monospores were isolated from wild strain. ASI4019 and their mating types were determined. We investigated the relationship between pigmentation on the plate and fruitbody color to understand genetic relationship among F. velutipes strains. Dikaryotic strains mated between nonpigmenting strains produced white fruitbodies. However dikaryon obtained from mating between nonpigmenting monokaryon and brown pigmenting monokaryon produced brown fruitbody as the dikaryon obtained from mating of brown pigmenting monokaryons. The white fruitbody from wild strain was distinguished from that of commercial strain. When the nonpigmenting wild monokaryon was mated with commercial monokaryon, pale brown mushroom was produced. The BC1F1 was obtained by mating the above mentioned $F_1$ with commercial monokaryon. Fruitbody color of BC1F1 shared two types; one strain with all pale brown fruitbodies, and the other strain with separated eight pale brown and two mixed type involving pale brown and white fruitbodies.

팽이버섯 야생종과 재배종들의 esterase isozyme 밴드패턴을 비교하고 그 중 특정 야생종 ASI 4019균을 단포자 분리후 교배형을 결정하였다. 단포자의 PDA plate상에 색소 집적과자실체 형성관계를 비교한 결과, 갈색 색소를 집적시킨 단포자와 색소를 집적시키지 않은 단포자간 교배시 갈색 자실체를 형성하였으며 색소를 집적시키지 않은 백색 단포자간 교배한 결과 백색 자실체를 형성하였다. 백색자실체는 재배종의 백색과 색택이 다르게 나타났다. 백색 균사체를 나타내는 단포자와 재배종 단포자를 교배한 결과 연갈색 자실체가 나타났으며 이 Fl의 단포자를 재배종 단포자와 여교배하여 BC1F1을 비교한 결과 1계통은 연갈색 자실체만 형성하고 또 다른 한계통은 연갈색 자실체 8개, 연갈색과 백색 자실체가 혼합된 것이 2개 있었다.
