Abstract


Delicious the mushrooms (Panellus edulis), fleshy, delicate, fragrant, good taste, rich in protein, vitamins and minerals and other nutrients. Our country, especially in the Northeast famous wild edible mushrooms. Due to the relatively short history of delicious mushroom cultivation, the bacteria used in the production of multi-domesticated from wild serious strains degradation, with the needs of market diversification, improvement and breeding of new varieties is imperative. Of incompatibility factor delicious mushrooms and the incompatibility factor analysis in breeding research has not been reported. This test is never affinity factor analysis of the the delicious mushrooms genetic characteristics, combined with a single - single cross-breeding breeding high-yielding, early maturing, commodity character excellent new varieties of delicious mushrooms. The results are as follows: (1) delicious mushrooms incompatibility factor constitutes an ear strains as test material, optical microscopy and fluorescence microscopy microscopy lock like joint indefinite the mononuclear strains from a single spore isolates 25, of these 25 single-core strains using three mating, and through linkage analysis with the card square test, indicating that the delicious mushrooms of A, B incompatibility factor of four mating type meet 1:1:1:1 separation law, which explicitly the delicious mushroom into four polarity mushroom. (2) delicious mushrooms for the test strains mating, determine the A, B incompatibility factor 55 and 138, capable of forming a dual-core with different genetic diversity of delicious mushrooms incompatibility factor of 6 210, pursuant to calculate the total number of its possible incompatibility factor of 7590. (3) delicious mushrooms affinity of the evaluation and selection through 12 delicious mushroom strains mycelial growth, growth period, commodity traits investigation and comparison of the yield and quality, screened four excellent parental strains. The results are as follows: higher yield strains of wild Asian ear and the Asian ear cr-b; the commodity good traits strains for wild Asian ear, ear of Asia CR-b and sub-ear cr-c; temperature resistant strains of wild Asian ear; mycosis Valley Huang linggu, strains of early maturing variety, growth period of only 110D. (4) delicious mushroom hybrids identification and screening of this study for the hybrid strains of hybrids is difficult to accurately determine the problem, put forward a set of reliable scientific authenticity of the hybrid strain identification, screening breeding program. Broodstock collection spores → → spores diluted → mononuclear strain confirmation (optical microscopy screening, the double staining re-examination) → hybrid combinations (combined with genetic background) → identification of the authenticity of the hybrid strains (microscopy judgment lock-like joint No, antagonism preliminary determination of the physiological characteristics of the similarities and differences with the pro-esterase isozyme further determine the hybrid strains derived from the two parental true hybrids) → screening of hybrid strains (physiological properties of esterase isozymes mycelial characteristics , of hair fungus characteristics and fruiting characteristics screening new hybrid strains suitable for growing or have some good traits) → the regional test → production test. (5) delicious mushroom new varieties of hybrid breeding using four elite parental filter out two high-yielding hybrid strains CG3 BD6, the commodity character excellent hybrid strain CD6 and a precocious high-yielding hybrid strains CG10. CG3 biological efficiency of 91.3%, super pro, respectively 5.6% and 19.3%; a BD6 the biological efficiency of 80.3%, super pro, respectively 22% and 1.3%; the CD6 goods traits better quality; CG10 growth period shorter, the whole growth period is 110d, 4 hybrid strains of bacteria have a development value.
