Summary:Pleurotus spp. strains were selected in order to improve commercial cultivation under local conditions. Productivity and other characteristcs associated to production were evaluated in 2 experiments with 15 different commercial strains of Pleurotus spp. Productivity of several strains was not influenced by the type of heat treatment used for substrate preparation (sterilization or pasteurization). Incubation period for fruiting initiation, cropping period, maximum productivity, size and morphology of fruits bodies were monitored. Differences were observed among the strains. Two strains (IAP and PCM) were selected since they showed high yields (about 100% biological efficiency) in short cropping periods (7 to 10 weeks). Their fruit bodies were middle sized (9 to 10 g) with white yellowish color and good consistency. Partiendo de 15 cepas comerciales de Pleurotus spp. de distinto origen, se identificaron las mas adecuadas para mejorar la produccion comercial de Pleurotus spp. bajo condiciones locales. Se evaluo tanto la productividad como otras caracteristicas asociadas a la produccion en dos experimentos. La productividad de las diferentes cepas no se vio influenciada por el tratamiento termico empleado para la preparacion del substrato (esterilizacion o pasteurizacion). Ciertos parametros de produccion como el tiempo de incubacion para el inicio de la fructificacion, el tiempo de cosechado, el maximo rendimiento, el peso promedio y la morfologia de los hongos fueron monitoreados, observandose marcadas cepas (IAP y PCM) por haber presentado altos rendimientos (aproximadamente 100% de eficiencia biologica), en periodos cortos de produccion (7 a 10 semanas) y esporoforos del tamano mediano (9 a 10 g) de color blanco amarillento y consistencia firme.
