论文摘要：
Simple sequence repeats (SSRs) were used to assess genetic diversity and study genetic relatedness in a large collection of Malus germplasm. A total of 164 accessions from the Malus core collection, maintained at the University of Illinois, were genotyped using apple SSR markers. Each of the accessions was genotyped using a single robust SSR marker from each of the 17 different linkage groups in Malus. Data were subjected to principal component analysis, and a dendrogram was constructed to establish genetic relatedness. As expected, this diverse core collection showed high allelic diversity; moreover, this allelic diversity was higher than that previously reported. Cluster analysis revealed the presence of four distinct clusters of accessions in this collection.
