A taxonomic survey of the Oriental pears

A taxonomic survey of the Oriental pears

Proc Amer Soc Hort Sci 51: 152-156

About 8 spp. of the Oriental pears are considered to be of pomological value, either as rootstocks or for their fruits. They are Pyrus ussuriensis, P. bretschneideri, P. pyrifolia, P. serrulata, P. phaeocarpa, P. betulaefolia, P. pashia, and P. calleryana. Among them only 3 are cultivated as commercial fruit trees in China and Japan. They are Pyrus pyrifolia, the sand pear; P. bretschneideri, the Chinese white pear; and P. ussuriensis, the Ussurian pear. The sand pear is most widely distributed, extending over entire central and southern region of China as well as in Formosa and Japan. The Ussurian pear is native to and commonly cultivated in the northeastern Provinces (Manchuria); the Chinese white pear, which is considered to be the best one in quality of the Oriental group, is mainly cultivated in the North China Plain and the Sungtung Peninsula.
