The invention discloses an
ultraviolet mutation breeding and
acclimatization method of a salt-resisting domestic
fungus. According to the invention, initial domestic
fungus strains are activated and are subject to
mycelium ultraviolet mutation; salt-resisting stains are subject to
primary screening,
acclimatization and secondary screening by using salt-containing selective culture media, such that the salt-resisting
stain is obtained. The method is suitable to be used in salt-resisting
stain breeding and
acclimatization of domestic
fungus varieties such as cap fungus, shiitake fungus and Jew's ear. The method is advantaged in that: the high-salt-resisting
mutation strain is obtained with the
mycelium ultraviolet mutation and acclimatization method, such that a novel approach of salt-resisting cap fungus breeding is developed. The operation processes are simple, a small amount of equipment is required, the cost is low, such that the domestic fungus breeding method is easy to popularize. A mutation period is short, a forward
mutation rate is improved, and an effect is substantial. The obtained strain has a salt-resisting capacity of 2%, stable hereditary characters, and excellent agronomic characters. When the method is used in the productions in
saline alkali lands, the quality of cap fungus fruiting bodies is improved; and a fresh-to-
dry weight ratio and a storing tolerance are improved by more than 50%. Therefore, the quality of cap fungus is effectively improved, the production cost is reduced, and the
economic benefits are substantially improved.
