Abstract：In order to explore the excellent strains of oyster mushroom suitable for factory cultivation and provide refer-ence for the variety breeding of oyster mushroom in factory cultivation,20 strains of Pleurotus ostreatus from different sources were used as test materials,the bag-filling time,mycelium growth potential,cap length,stalk length,stalk diame-ter,cap thickness,cap color,yield per packet,mycelium growth rate and biological efficiency of different P.ostreatus strains were determined.The comprehensive agronomic traits of different P.ostreatus strains were analyzed and evaluated by clustering and heat map analysis.The results showed that there were rich genetic diversities,the coefficient of varia-tion was 7％-58％,and 20 materials were divided into 3 groups in 5 places.The analysis of cluster heat map showed that the black strain Heifeng 268 and Shuangkangheiping strain were relatively good in agronomic traits and had great poten-tial for industrial cultivation.The experimental results provided the basis for the industrial exploitation and utilization of P.ostreatus resources and the selection and breeding of excellent varieties.
