Abstract

To develop a new cultivar of King oyster mushroom white variety (Pleurotus ferulae), GW10-95 as parental strain was selected by the method of Di-mon crossing between monokaryotic strain ASI 2850-24 derived from ASI 2850 and dikaryotic strain ASI 2803. The GW10-95(ASI 2803 ${\times}$ ASI 2850-24) was shown the best cultural characteristics, selected to be a new cultivar and designed as 'Beesan No.1'. The 'Beesan No.1' was formed incompatibility line distinctly in the confrontation growth of parental strains ASI 2803 and ASI 2850. Analysis of the genetic characteristics of the new cultivar 'Beesan No.1' showed a different DNA profile as that of the control strains, ASI 2803 and ASI 2850, when RAPD(Random Amplified Polymorphic DNA) primer URP6 was used. The optimum temperature and pH arrange for mycelial growth were $25^{\circ}C$ and pH5~8, respectively. Fruiting body production per bottle was about 245 g using demonstration farms. And also the stipe was thick and long. This new cultivar 'Beesan No.1' of Pleurotus ferulae was characterized by fast fruitbody formation, the stipe was thick and long and high quality yield compared to that of other cultuvars. We therefore expect that this new strain will increase of farmer's income by construction of stabilized production system.

아위느타리(Pleurotus ferulae)의 품종 육성은 수량성이 높은 ASI 2803과 형태적으로 보기 좋은 국내 교배품종 ASI 2850의 단포자를 분리하여 교배하여 13개의 교잡주를 우량계통으로 선발하였고, 수량성이 높고 형태가 좋으면서 자실체 형성이 쉬운 균주 GW10-95를 선발하여 '비산1호'으로 명명되었다. 고유특성으로는 균사체 배양의 대선형성유무에서 모균주 ASI 2803 및 ASI 2850과 대치배양하였을 때 뚜렸한 대선을 형성하였다. 유전적으로는 RAPD primer를 이용하여 신품종 '비산1호'의 DNA 패턴은 모균주와는 다른 패턴을 형성하였다. 가변특성은 균사생장 적온은 $25^{\circ}C$이며 pH의 범위가 pH5~8까지 넓게 형성되었다. 자실체 수량은 농가실증시험에서 245 g으로 높게 나타났다. 또한 대길이는 ASI 2803보다 길고 굵어 수량이 높게 나타났다. 기존의 아위느타리보다 수량성이 높아 큰느타리 대체품종 뿐만 아니라 수출 품종으로도 기대된다.
