Genetic diversity of Poncirus and phylogenetic relationships with its relatives revealed by SSR and SNP/InDel markers

The polymorphic markers of nuclear SSR (simple sequence repeat), SNP (single nucleotide polymorphism)/InDel (insertion–deletion length polymorphism), and cpSSR (chloroplast SSR) were used to evaluate the genetic diversity of 52 trifoliate oranges and their relatives. The two genomic DNA-based markers produced high values of PIC (polymorphic information content) at 0.45 for SNP/InDel and 0.32 for nuclear SSR, indicating that there is a large …
