Abstract：In order to evaluate the germplasm of oyster mushroom cultivated in Hebei province and find high-quality strains to be used as breeding samples, eighty-three oyster mushroom strains were collected. Antagonistic test of the 83 strains were employed to identify the same strain with different names. Internal Transcribe Spacer ( ITS) of the tested strains were sequenced to identify the molecular species. Mycelial growth rate on two natural substrates and antibacterial action to Trichoderma of the vegetative incompatible strains was determined. The results showed that the 83 tested strains were divided into 31 vegetative com?patibility groups including 15 strains of Pleurotus ostreatus,9 strains of P.floridanus,2 strains of P.cornu?copiae,one strain of P.pulmonarius and 4 strains of uncertain species. Two strains were screened that were most suitable for growing on cottonseed hull and two strains on cotton stalk. Seven strains were showed ex?cellent resistance to Trichoderma.These strains can be used as excellent samples for future breeding study.
