“…In addition, it is possible to construct very high density DNA marker maps for application in genome research and positional cloning of genes through this method (Monte-Corvo et al, 2000;Russel et al, 1997). Studies on the genetic diversity of Rubus species have been carried out, including species such as R. idaeus (Parent and Fortin 1993, Graham and Mcnicol, 1995, Graham et al 1997 and R. occidentalis (Parent and Page, 1998), as well as Asian species (Amsellem et al 2000). These studies employed AFLP, RAPD (Random Amplified Polymorphic DNA), RFLP (Restriction Fragment Length polymorphism), and SCAR (Sequence Characterized Amplified Region) markers, as well as SSR (Amsellem et al, 2000;Parent and Fortin, 1993, Graham and Mcnicol, 1995, Graham et al 1997Parent and Page, 1998).…”
