In order to screen the best strains of Pleurotus ostreatus suitable for cultivation with corn straw as the main substrate in Liaoning region,19 P.ostreatus strains were used as test materials in this study,the growth rate of mycelia in PDA,the time of filling the bag,the contamination rate in cultivation bag,the biological efficiency and the agronomic characteristics of 19 strains were compared.The results showed that the growth of mycelia of stock culture and cultivation bag were not completely corresponding to the biological efficiency of fruiting body.In production,mycelium growth,fruiting body traits,biological efficiency and other index should be comprehensively considered for the selection of strains.The comprehensive characteristics of strain C14 were best,although the mycelium growth in PDA and corn stalk matrix were moderate,but its biological efficiency was high,its fruiting body was dark and compact,with short stalk,large and tough type,thick and medium size cap and thick edge.It can be used for the production of excellent strains.The fruiting body character of strain C10 and C2 were general,but their parent species and straw cultivation substrate had excellent characters on fast growth,biological efficiency and strong straw utilization ability,which could be used as an alternative parent material for breeding.
