honeysuckle germplasm SPL007
This study evaluated the population structure, genetic relationship, and fingerprints of 39 germplasm resources of Lonicera in China using simplified genome sequencing technology. A total of 13,143,268 single nucleotide polymorphisms (SNPs) were identified. Thirty-nine samples of Lonicera were divided into four subgroups, and the population structure and genetic relationship of existing Lonicera germplasm resources were determined using PCA, population structure, and phylogenetic tree analysis. Through several stringent selection criteria, 15 more streamlined high-quality DNA fingerprints were filtered out from the validated 50 SNP loci and verified as being able to effectively identify 39 Lonicera.
