摘　　要：2010~2016年在云南省德宏植胶区对‘热垦525’、‘热垦628’、‘热研8-79’、‘热研7-33-97’、‘湛试327-13’、‘IAN873’、‘云研77-4’7个橡胶树品种进行区域性栽培试验,调查比较其定植成活率、茎围生长量、抗寒性等性状。结果表明:不同橡胶品种,其定植成活率、茎围生长速度、抗寒性不同,‘湛试327-13’阳坡的成活率最高,为95.2%;阳坡生长由快慢顺序为‘热研7-33-97’>‘热垦525’>‘IAN873’>‘热垦628’>‘云研77-4’>‘湛试327-13’>‘热研8-79’;阳坡抗辐射型寒害能力强弱顺序为‘湛试327-13’>‘云研77-4’>‘热垦525’>‘热研7-33-97’>‘热研8-79’>‘IAN873’>‘热垦628’;从成活率、茎围生长量、抗寒性阳坡的数据来看,‘热研7-33-97’品种生长速度较快,‘湛试327-13‘品种成活率和抗寒性较好。The regional trial of rubber clones ＇Reyan 525＇ , ＇Reyan 628＇ , ＇Reyan8-79＇ , ＇ Reyan7-33-97＇ , ＇Zhanshi327-13＇, ＇IAN873＇, and ＇Yunyan77-4＇ were conducted in Dehong, Yurman province, China during 2010-2016. The survival rate, girth growth and cold resistance of these clones were observed and compared. The results showed that these clones varied in their survival rate, girth growth and cold resistance. The clone ＇Zhanshi 327-13＇ had the highest survival rate （95.2%） at the sunny slop of the hill. The clones grew faster at the sunny slop in the order of ＇Reyan7-33-97＇〉＇Reyan525＇〉 ＇ IAN873＇ 〉 ＇ Reyan628＇ 〉＇Yunyan77-4＇ 〉 ＇ Zhanshi327-13＇ 〉 ＇ Reyan8-79＇ ; The clones were tolerant to radiation cold injury in the order of ＇ Zhanshi327-13＇ 〉 ＇ Yunyan77-4＇ 〉 ＇ Reyan525 ＇ 〉＇ Reyan7-33-97＇ 〉 ＇Reyan8-79＇〉 ＇IAN873＇〉＇Reyan628＇. The clone ＇Reyan7-33-97＇ grew faster based on the data of the survival rate, girth growth and cold tolerance of all the clones at the sunny slope of the hills, and the clone ＇Zhanshi 327-13＇ showed a higher survival rate and higher cold resistance.
