[Method] During three consecutive years from 2011 to 2013, phenophase, botanical traits, economic traits and stress resistance of two introduced peach cultivars, Xinchuanzhongdao peach and Yanhong peach, were investigated and compared. [Result] Under local scientific management conditions, Xinchuanzhongdao peach and Yanhong peach exhibited relatively strong and strong tree vigor, respectively; the branch generation rate was 55.92% and 55.81%, respectively; the branching rate was 28.39% and 23.26%, respectively; the leaf size was 17.1 cm×4.2 cm and 19.5 cm×5.0 cm, respectively; the corol a size was 4.8 cm×4.7 cm and 4.8 cm×4.9 cm, respectively; the fruit setting rate was 43.19% and 26.66%, respectively; fruits of Xinchuanzhongdao peach and Yanhong peach were matured in mid-late July and late July-early August, respectively; the average weight per fruit was 195.5 and 216.9 g, respectively; the sugar content was 13.5% and 15.8%, respectively; the average yield per plant was 41.3 and 43.1 kg, respectively; the edible rate was 94.35% and 93.81%, respectively; both Xinchuanzhongdao peach and Yanhong peach exhibited adaptability. [Conclusion] Comprehensive comparison results suggest-ed that Xinchuanzhongdao peach exhibited better performance compared with Yan-hong peach and these two peach cultivars could be developed appropriately with supporting cultivation techniques in Guiyang City.展开更多
