Abstract: ‘Zhongnong Chuanxing 1’,a new cultivar of edible Pleurotus eryngii originated from IUA-Pe20 strain as parental material,was by multi-spore self-fertilization and directional breeding. The mycelia exhibits a pure white coloration,with an optimal growth temperature of 25 ℃ and a average growth rate of 0.48 cm · d^-1. The optimal temperature for mushroom production is 16 ℃,with a cultivation period of 52-53 d. The fruiting bodies are clustered with moderate and small size. The pileus displays a light gray coloration and demonstrates low susceptibility to cap expansion. The lamellae are decurrent and relatively narrow,while the stipe is clavate with dense flesh. This cultivar exhibits high productivity,with an average fresh mushroom yield of 512.5 g per bag. Additionally,it demonstrates superior commercial quality due to its high crude protein content and amino acids content. It is suitable for factory cultivation.
