摘　　要：通过对山杏进行种源苗期、林期试验和RAPD分子标记实验,结果表明:种源间苗高、地径、冠幅等性状存在极显著差异,且广义遗传力较高;内蒙古东西部山杏种源间差异明显;山杏性状间具有相关性;初步选择出敖汉旗为最佳种源;种源间遗传分化程度较高,种源内遗传多样性排序为敖汉旗>巴林右旗>乌拉山>万家沟。本文为山杏遗传改良和合理开发利用提供了研究基础和科学依据。The result of provenance trial and RAPD molecular markers experiment of Armeniaca sibirica showed that the characters such as height, ground diameter and crown , were distinct different among provenance, genetie ability is high. There was signifieant difference between east and west provenanee of Armeniaca sibirica in Inner Mongolia. Correlation existed among traits. Aohanqi was seleeted as the exeeUent provenance. The genetie variation of provenanee was signifieant. Scientific foundation could be provided for genetie improving and use of Armeniaca sibirica.
