【 Objective】 To investigate the main fruit characters of different types of Xinjiang peach germ- plasms in southern Xinjiang and provide the basis for the utilization and protection of peach varieties.【 Method】The field observation and sampling determination method was applied to analyze and evaluate the real characters of peach screening survey in Xinjiang.【 Result】 The results showed that there was significant differ-ence of frutescence （from early July to the late October） among twenty - five peach varieties. Furthermore, there were diverse quality traits among the fruit trees. For instance, the weight of single fruit was between 70. 00 g and 279. 80 g, and the soluble solids content of the fruit was between 10. 48% and 20. 58% . The ed-ible rate was between 91.81% and 97.39% , and the fruit shape, color, meat quality, flavor and so on were diversified.【 Conclusion】 From the 25 main types of Xinjiang peach, we have screened out premature type： Aketai peach, medium maturing types： Akemianshan peach and Kuokemiangsha peach, late maturing type： Axixiapu peach, and high solid type： Shufu No. 7, and so on.
