摘　　要：[Objective]This study aimed to compare the biological traits of Xinchuanzhongdao peach and Yanhong peach and provide basis for screening high-quality peach cultivars adapting to climate characteristics in Guizhou Province. [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＆#215;4.2 cm and 19.5 cm＆#215;5.0 cm, respectively; the corol a size was 4.8 cm＆#215;4.7 cm and 4.8 cm＆#215;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.[目的]比较新川中岛和艳红桃2个桃品种的生物学性状,以期为筛选出适应贵州省气候特点的优良桃树品种提高依据。[方法]连续3年(2011～2013)调查新川中岛、艳红桃2个在当地表现较好的引进桃树品种的物候期、植物学特性、经济性状和抗逆性等内容,并进行比较筛选。[结果]2个桃品种在当地科学管理条件下,从综合比较结果看,新川中岛和艳红桃的树势分别表现为较强和强,枝条萌芽率分别为55.82%和55.81%,成枝率分别为28.39%和23.26%,叶片大小分别为17.1 cm×4.2 cm和19.5 cm×5.0 cm,花的大小为4.8cm×4.7 cm和4.8 cm×4.9 cm,座果率分别为43.19%和26.66%,成熟期分别为7月中下旬、7月下旬～8月上旬,平均单果重分别为195.5和216.9 g,含糖量分别为13.5%和15.8%,单株产量分别为41.3和43.1 kg,果实可食率分别为94.35%和93.81%,都表现为适应性强。[结论]从综合比较结果看,新川中岛品种表现很好,艳红桃品种表现较好,适合在该地区适量发展。
