摘　　要：对收集的10份桑树资源,分析桑ITS序列并结合农艺性状调查,从分子学和形态学角度探讨10份桑种质资源的遗传背景和亲缘关系,为桑树种质鉴定、品种登记和遗传育种提供参考。结果表明:R-2016HYB2-2、R-2016KJ-1、R-2016 JLJ-1、湖桑32、R-2016LH-2和R-2016XYJL-2属于白桑类。R-2016BL-2和R-2016CS2-2属于蒙桑类,R-2016SM-3为鸡桑类。R-2016HYB1-2为暹罗桑类,属于泰国的引进品种。10 mulberry germplasm ITS sequences were determined and agronomic characters were investigated to provide references for germplasm indentification,species registration and genetic breedind of mulberry.The results showed that R-2016HYB2-2,R-2016KJ-1,R-2016JLJ-1,Husang32,R-2016LH-2 and R-2016XYJL-2 were belonged to the Morus alba,R-2016SM-3 was M.australis and R-2016HYB1-2 was M.rotunbiloba,belonged to introduced varieties from Thailand.
