Abstract
In this study, three species of oyster mushroom (Pleurotus osturatus, P. eryngii and P. cornucopia) were crossed together in order to aggregate benefit special attributes to the genotype (s). The monokaryon of each of these species was prepared. Then, the monokaryons of two species were placed at 5 mm distance from each other to produce dikaryon. The results showed that, from among 700 crosses, only the crosses of eryngii and osturatus monokaryons were grown toward each other and produced clamps (dikaryons). Four produced hybrids were noted H1, H32, H11 and H40. The spans of produced hybrids were prepared; then, they were grown into sterile media and attributions of hybrids were studied. The results indicated that H11 hybrid was an appropriate hybrid in terms of the number of days until growing, number of days until the observation of the first pin and the days from planting to harvest. However, H40 was the best hybrid based on cap diameter, dry and fresh weight of fruit body, yield and biomass. It is expected that these interspecific hybrids employ for future oyster mushroom breeding programs.
