Mitochondrial DNA Restriction Fragment Length Polymorphisms inMalusSpecies

摘要

AbstractThree apple (Malus×domestica) cultivars and 11Malusaccessions have been investigated by the probe hybridization method on their mitochondrial DNA (mtDNA). The gene probes used were:coxI, coxII, atpA, atp6, andatp9.Our results revealed enough variation to characterize ten mtDNA haplotypes among theMalusgenotypes examined. The taxonomic and phylogenetic implications of mtDNA polymorphism are also discussed
