✦ Synopsis

RAPD (random amplified polymorphic DNA) markers were used to fingerprint eight commercially available apple rootstocks (Nertchinsk, Northern Spy, Osman, Heyer 12, M.1, M.9, M.26 and MM.106), 10 winter hardy offsprings derived from the cross of Nertchinsk x M.9, six winter hardy offsprings derived from the cross of Nertchinsk x M.26 and one winter hardy offspring derived from each of the two crosses between Osman x Heyer 12 and Northern Spy x M.1. Phylogeny analysis using parsimony allowed us to draw the genetic relationship between these lines using only RAPD markers data. The resulting cladogram was compared to the true genetic relationship between these lines in order to assess the efficiency of RAPD markers in determining accurately the phylogenetic relationship. We also developed a DNA fingerprinting system based on 13 informative RAPD loci amplified by five RAPD primers that allowed the rapid identification of apple rootstocks.
