Abstract: 

The majority of breeding programs of edible mushrooms are carried out in the button mushroom due to its commercial importance and genetic difficulties. In this research, for the first time in Iran, it was possible to examine intra-hybridization and its effect on both productivity and mycelium morphology as a potential for commercialization. The strains comprised six heterokaryons and four homokaryons from different sources. Twenty five homokaryotic isolates were obtained from six heterokaryon and having 29 homokaryons, 406 diallele crosses were performed from which 145 crosses were compatible. Productivity of compatible crosses was examined in an industrial mushroom farm on a basis of randomized complete block design with two replications. From 145 crosses, nine hybrids which had significantly higher yield than the control, were used in yield trials performed in two industrial mushroom farms on a completely randomized design basis with three replications. The yield of three hybrids was significantly higher than the control. For these hybrids, a strain registration form was prepared. The resulting information showed some interesting points, particularly about the study of pedigree of offspring having high performance than the control, which will be useful in designing the future breeding programs.
