Abstract: [Objective] To investigate the main fruit characters of different types of Xinjiang peach germplasms 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 difference 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 edible 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.
