Abstract:

In order to screen out highly polymorphic cpDNA and ITS sequence primers for studying the molecular pedigree of natural populations of wild rose, 8 wild rose populations were used as test materials, 12 pairs of chloroplast genome primers and 4 pairs of nuclear genome ITS primers were adopted. PCR amplification and PCR product sequencing, four pairs of high polymorphic primers trnL-trnF, rpl20-rps12, rbcl, and ITS1 were screened out. Sequence variation calculation and phylogenetic tree results showed that 8 wild rose populations had low variation and could be divided into 2 branches. Three pairs of highly polymorphic cpDNA primers and 1 pair of ITS primers were screened, which were suitable for studying the phylogeny and pedigree of wild rose, and could further explore the pedigree of endangered species of wild rose.

Key words: wild rose, ITS sequence, sequence screening, phylogenetic tree
