PROBLEM TO BE SOLVED: To provide a strain giving a mushroom having following features that its cultivation period is short, there is no need to treat it at a low temperature for growth, the shape and nature of carpophore is good and its size is large, and the packaging/transportation at distributive stage is easy since a pileus is developed to be almost free of a stem or a stem is developed and a pileus is hardly developed, as well as its mouth feeling is good.SOLUTION: Disclosed is a novel Pleurotus eryngii var. tuoliensis/Pleurotus eryngii hybrid strain which includes Pleurotus sp. AFRL 6562 (FERM P-21048) and Pleurotus sp. AFRL 6563 (FERM P-21049), and in which cultivation period, growth treatment, the shape of pileus, and the shape of stem can be improved as desired.COPYRIGHT: (C)2008,JPO&INPIT【課題】栽培期間が短く、発生に低温処理が必要なく、子実体の形質が良く、大型で、傘が発達して柄が殆どないか、あるいは柄が発達して傘が余り発達せず、よって流通段階での包装・運搬が容易であり、且つ食感の良いきのこが得られる菌株を提供すること。【解決手段】栽培期間、発生処理、傘の形状、柄の形状ともに所望のものに改良し得た、Pleurotus sp. AFRL 6562(FERM P-21048)およびPleurotus sp. AFRL 6563(FERM P-21049)菌株を含むバイリング・エリンギ新交配株を提供する。【選択図】なし
