New several genotypes are found in the forests of the eastern Guilan province that are morphologically more like the Asian pears and have also some agronomical important traits such as very large, high quality of fresh fruits, and relative resistant to fire blight disease. In the present study, eleven microsatellite markers were used to assess the genetic relationships between these Iranian genotypes Asian pears. The UPGMA cluster analysis located the 20 genotypes into two main groups. The first main group had two subgroups including seven native genotypes and commercial Asian pears. The second group also had two subgroups involving the interspecific hybrids of Asian and European pears, and Bartlett pear. We were found a major population of the Asian pears that were grown in the northern forests of Iran and it seems that these forest are secondary centre of origin of Asian pear.
