Abstract
To identification, classification of crabapples cultivar, and parental selection in the breeding of new varieties, the
genetic diversity of 31 ornamental crabapples from Euramericanshowing a good adaptability in north China was analyzed using
amplified fragment length polymorphism (AFLP) markers. Ten pairs of primers with clear, stable bands and high polymorphism of
bands was selected from 94 pairs of primers. There were 601 bands were produced, of which 519 bands were polymorphic that had
86.22 percent of the total bands. For the 31 samples, Nei’s gene diversity index was ranged from 0.184 4 to 0.313 0, with an average
of 0.240 6; Shannon information index was from 0.300 5 to 0.470 8 with the mean of 0.376 5, which suggested that therewas high
levelof genetic variation among the 31 crabapples. The UPGMA cluster analysis revealed that 31 samples formed five distinct groups
at 0.204 genetic distance. Two Groups were composed of 17 and 11samples separately, and only one sample in each of other groups,
which revealed the genetic relationship of 31 ornamental crabapples, and confirmed the rationality in morphological classification
ofthe tested materials.
