Abstract

The invention provides a method for performing mating type gene identification on a basidiospore monocaryon strain which is separated from different hypsizigus marmoreus strains. In the identifying process, in particular application of a flushing reaction, a palisade reaction and transplanting, the method can primarily identify the mating type gene of the hypsizigus marmoreus intuitively and quickly without other instruments and equipment. When the method is applied in cross breeding, the mating type gene of basidiospore monocaryon parent and progeny strains can be identified conveniently so as to improve the purposiveness and the effectiveness of the cross breeding process. The adopted method can shorten the time for identifying the mating type gene for 5 to 10 days, reduce the number of comparing-screening strains by 75 percent theoretically in cross breeding, improve the fecundity, and is more convenient and efficient particularly in application of multiple cross breeding of multiple strains. Then, the method selects the compatible basidiospore monocaryon strain having clamp connection according to the identification result to carry out biparental crossing, and screens hybrid strains according to growth speed, growth potential and economical character index, thereby obtaining stable, high yield and high quality hybrid strains.

Description

Technical field: [0001] The invention relates to the technical field of biological genes, in particular, according to the identification method of the mating type gene of the basidiospore monokaryon of chrysanthemum, the initiative and effectiveness of single-single hybrid breeding of chrysanthemum can be improved. Background technique: [0002] True Ji mushroom [Hypsizygus marmoreus (Peck) Bigelow], also known as crab-flavored mushroom, seafood mushroom, Hongxi mushroom, jade mushroom, gelatinous jade mushroom, belongs to Basidiomycotina, Phytomycetes, Agaricaceae, White Mushrooms , Lipophyllum family, and Amygium genus are rare edible fungi that are crisp and tender in texture, delicious in taste, rich in nutrition, and have various health benefits, and are deeply loved by consumers. [0003] At present, some large-scale edible fungus enterprises in my country, Japan, and South Korea have been able to carry out factory cultivation of shimeji mushrooms by controlling temper...
