Abstract:
In order to provide reference for utilization in breeding the ploidy of 25 accessions of hawthorn germplasm resources was measured by flow cytometry and comparison was drawn with others previous measurement by young leaf squash and chromosomes counting method.The results showed that the ploidy of 14 accessions was identical with previous measurements，the ploidy of 6 accessions was different from previous results，and the ploidy of 5 accessions was reported for the first time.This research showed that flow cytometry was a high efficient method for ploidy measurement of hawthorn germplasm resources，and ploidy measurement in this research provided reference for the proper utilization of the germplasm resources in future hawthorn improvement and cross breeding.
