Abstract：To analyze the diversity of germplasm resources of Pleurotus eryngii strains,this study screened excellent strains with short growth period and high yield as industrial breeding materials,aiming to provide theoretical basis for the in-depth development of P.eiyngii breeding technology.In this study,34 strains of P.eryngii(Bl-B34)collected domesti-cally were used as test materials,and the somatic cell incompatibility experiment,ISSR molecular marker technology,and agronomic trait evaluation were compared and analyzed,and the excellent hybrid strains were selected.The results showed that the 34 strains of P.eryngii were rich in genetic variation,with a genetic similarity coefficient from 0.73-0.97.When the genetic similarity coefficient was 0.85,the 34 strains of P.eryngii could be classified into four categories.The agronomic traits showed that the highest total yield was B2,and the lowest yield was B7.The shortest growth period was B1,which took only 63 days,while the longest growth period was B11,B14 and B30,all of which took 80 days.Based on the analysis of the above results,the B2 strain with high yield and high biological efficiency and the B1 strain with short growth cycle were selected as hybrid breeding parents.Finally,the excellent hybrid strain LX119 was screened,with a growth period of 56 days and a yield of 762.14 g·bag-1.
