The primer group comprises a fast-feathering primer pair and a slow-feathering primer pair, the nucleotide sequence of a forward primer of the fast-feathering primer pair is shown as SEQ ID No.1, and the nucleotide sequence of a reverse primer of the fast-feathering primer pair is shown as SEQ ID No.2; the nucleotide sequence of a forward primer of the slow feathering primer pair is shown as SEQ ID No.3, and the nucleotide sequence of a reverse primer of the slow feathering primer pair is shown as SEQ ID No.4. According to the fast and slow feathering auto-sexing genetic principle and the designed fast and slow feathering genetic typing specific primers, fast feathering, slow feathering and slow feathering heterozygotes and homozygotes can be rapidly distinguished, a homozygous slow feathering strain is cultivated, and fast and slow feathering auto-sexing of commercial generations is achieved.

Macrofungus cuvette seed culture medium and method for producing the same
InactiveCN101173219BNitrogen ratio is betterReasonable nitrogen ratioFungiMicroorganism based processesBristlegrassesNutrient solution
The invention discloses a large culture medium of epiphyte test tube and a preparation method. The culture medium is made by nutrient solution moistening amur foxtail or grass-seeds of green bristlegrass and the weight rate of the grass-seeds and the nutrient solution is 1 to 0.2 to 0.5. The surfaces of the grass-seeds are best moistened in and adhered with the nutrient solution. The test tube made by the culture medium can accelerate the growing speed of hypha and the time of the hypha filling with the test tube is two days earlier than the time when being grown in PDA, ten days earlier thanthe time when being grown in wooden meal and seven days earlier than the time when being grown in bamboo grain or wooden grain. The amount of seed grown in one test tube is equal to the amount of seeds grown in the test tube with PDA culture medium and going through three grades regeneration due that the grass-seed grain has the advantages of small volume, hard shell, good potential for growing epiphyte, low pollution as well as large surface and good dispersibility. The invention can be connected with the mushroom-produce bag and can reduce the culturing cycle by seventy days. The invention has the advantages of high producing efficiency, low production cost, low labor intensity and high commercial efficiency.
