Establishment and application of an SNP molecular identifica-tion system in Grifola frondosa

Germplasm resources of edible fungi are the basis of breeding excellent varieties. Accurate analysis and evaluation of the genetic diversity of Grifola frondosa germplasm resources and clear genetic relationships among strains can provide the scientific basis for the selection of breeding parents. A total of 1,706 high-quality loci were screened from 2,125,382 SNPs obtained by sequencing 60 Grifola frondosa
