''Pyrus'' × ''sinkangensis'', the Xinjiang pear, has been suspected to be of complex hybrid origin involving ''
P. communis'' and
Chinese white pear
Chinese can refer to:
* Something related to China
* Chinese people, people of Chinese nationality, citizenship, and/or ethnicity
**''Zhonghua minzu'', the supra-ethnic concept of the Chinese nation
** List of ethnic groups in China, people of va ...
s based on their
morphological characteristics.
Cultivars of ''P.'' × ''sinkangensis'' vary considerably, combining characteristics of both ''P. communis'' and Chinese white pears. Generally, the fruit shape of this species is much similar to ''P. communis'', but with a long
pedicel
Pedicle or pedicel may refer to:
Human anatomy
*Pedicle of vertebral arch, the segment between the transverse process and the vertebral body, and is often used as a radiographic marker and entry point in vertebroplasty and kyphoplasty procedures
...
. Some cultivars of ''P. × sinkiangensis'' bear fruits with a persistent
calyx and strong aroma, needing ripening before being edible, which is similar to ''P. communis''. On the other hand, fruits of some cultivars are juicy and crisp and not needed for ripening, which is like Chinese white pear.
New information from DNA-based markers indicates that ''P.'' × ''sinkiangensis'' usually produced complex
RAPD profiles, at least ''P. communis'', ''
P. armeniacifolia'' and Chinese white pears or sand pears have been involved in the origin of Xinjiang pears.
