摘　　要： 在湖北武汉的北部山区发现一种与板栗有较高嫁接亲合性的茅栗居群,3～5年生该茅栗居群做砧木与当地品种大红袍嫁接成活率在80%以上,嫁接后20年仍然能正常结果;应用RAPD技术分析该居群与栽培板栗品种、野生板栗、锥栗的遗传关系,表明该茅栗居群与板栗的亲缘关系紧密,尤其与野生板栗接近。分析认为该茅栗与板栗嫁接亲和性高的原因可能是该茅栗居群"渗入"更多的板栗基因。 One seguin chestnut population with high graft compatibility to Chinese chestnut(C. mollissima)was discovered in a northern mountain in Wuhan, Hubei province. The graft survival rate was more than 80% when 3～5 years seedlings of this seguin chestnut population were used as rootrocks and a local Chinese chestmut variety, Dahongpao, was performed as scions. Moreover, the scions were still fruiting normally after 20 yeras. RAPT method was conducted to analyses the genetic relationship among seguin chestnut, cultivated Chinese chestnut, wild Chinese chestnut (C. mollissima) and C. henryi. The high graft compatibility between seguin and Chinesenut might be due to permeation of genes from Chinese chestnut to seguin chestnut.
