摘　　要：[目的]筛选出承德地区抗寒性强的杏品种。[方法]对11个杏种质资源地上部分冻害发生情况进行田间调查,评估其冻害程度。[结果]编号为001的品种抗冻性最好,冻害程度最低,为无冻害;编号为105、130.15、甜仁1、甜仁2、91的品种抗冻性次之,冻害程度为轻度冻害;编号为032、中仁5号、旦杏、南杂、034的品种抗冻性最差,冻害程度为中度冻害。[结论]该研究为承德市乃至冀北地区杏品种引进和筛选提供了参考。[Objective] The aim of this study was to screen out apricot varieties with strong cold resistance in Chengde area. [Method] The occurrence of freezing injury in aboveground parts of 11 apricot germplasm resources was investigated in the field,and the degree of freezing injury was evaluated. [Result] The variety numbered 001 had the best freezing resistance and the lowest degree of freezing injury,which was no freezing injury. The freezing resistance of varieties numbered 105,130.15,Tianren 1,Tianren 2 and 91 followed,and the degree of freezing injury was mild. The varieties numbered 032,Zhongren 5,Danxing,Nanza and 034 had the worst freezing resistance and moderate freezing injury. [Conclusion] This study provided a reference for the introduction and screening of apricot varieties in Chengde and even in northern Hebei.
