The present invention relates to the mating type of mushroom (mating type), kind or system differentiation detector and the judgment methods used, can distinguish specific 8 kinds of A mating types and 7 kinds of B nodal patterns using the method sought with tooth discrimination teaching type, kind or system. Moreover, the method based on visiing type information according to different schools, about colic pain mushroom. According to the present invention, the mating type of mushroom, kind and system are very accurate, it can differentiate, based on different information, based on high success rate, it can mate, compared with existing panmixia method, the expense burden of labour and economy can greatly reduce. In addition, can carry out the selection between monokaryon bacterium master due to the differentiation that can carry out mating type, there is very big contribution to the new varieties of mushroom. Moreover, the present invention can compare in the protection of the kind similar to the genetic differences between morphologic two kinds, after new varieties and discharge process, have the advantages that highly beneficial.
