Four commercial strains of Pleurotus ostreatus were cultivated at the pilot plant level on rice straw as substrate. In all strains, three harvest were obtained, except in one that only presented two, in a period of 41 to 59 days. The parameters evaluated were days in the formation of fruiting primordia, the pileus diameter (three groups G1: <5 cm; G2: of 5 to 9.9 cm; G3: >10 cm), biological efficiency (BE), yield (Y) and production rate (PR). Strains CP-281 and CP-753 showed the highest production with 261.1% and 240.6% of BE, 60% and 55.3% of Y, 5.2% and 5.8% of PR, respectively. Next, CP-245 strain showed 213.3% of BE, 49% of Y and 3.8% of PR. Lower production was presented on CP-50 strain (EB 170.9%, Y 39.3% and PR 4.2%). The fours trains can be cultivated in small or large scale in several regions of Mexico.
