A survey for the distribution, utilization and conservation of fruit tree genetic resources was conducted in south-western part of Xinjiang Uygur Autonomous District of China in cooperation with scientists of Xinjiang Academy of Agricultural Sciences from September 2 to 10, 2006. The abundance and diversity of the pear and stone fruit were observed in the region visited. Local varieties and seedlings of peach (Prunus percica ) and Xinjiang peach (P. ferganensis ) were observed in the region surveyed. Local variety 'Suan Mei', which is thought to be P. domestica , is cultivated in south-western part of Xinjiang Uygur Autonomous District. Local varieties of three Pyrus species, P. × bretschneideri, P. armeniacaefolia and P. communis and their interspecific hybrids are distributed mainly in south-western part of Xinjiang Uygur Autonomous District. Besides these three species, P. betulaefolia is used as rootstock for Pyrus. But the diversity of these local varieties is rapidly declining with the spread of commercial cultivars that were introduced from other provinces. Analyses for genetic diversity of pear and stone fruits based on molecular markers were carried out.
