Abstract: A new Pleurotus ostreatus cultivar‘Xinyan 5’was obtained by single-spore hybrid breeding technique,using gray-black fruiting body cultivar‘Xiaoheiping’and the Xinyang traditionally cultivated cultivar‘Jingping 1’as parents. Its mycelial growth rate is fast,with a growth period of 30-40 days. The number of mushroom buds is moderate,with buthy fruiting body,a large flower shape,a large number of leaves,a grayish brown cap,a hard stipe and a soft flesh. It has strong adaptability and is suitable for facility cultivation in Henan Province. It has stable cultivation performance in various regions,with a three-tride yield of 918.13 g per bag and a biological efficiency of 91.8%.
