Study on numerical taxonomy of some fruit characteristics of cherry germplasm resources

In order to normalize the descriptors and data standard of cherry germplasm resources,investigation and statistical analysis were carried out on fruit top shape,suture,flush degree,fruit abscission from stalk,average fruit mass,average fresh stone mass,average length of stalk and average thickness of stalk of 203 cherry germplasm resources in Cherry Germplasm Repository of Zhengzhou Fruit Research Institute for 3 years.The results showed the fruit phenotypes of cherry germplasm resources were quite rich.A kind of new descriptors and reference cultivars were given for cherry by statistical data.The new descriptors should be more consistent with international criteria and the actual situation of cherry germplasm resources,and be easy for use.
