In this study,a regional trial for new ramie variety (line)was executed in eight regions including Yichun (Jiangxi),Dazhou (Sichuan),Changsha(Hunan),Xianning(Hubei),Nanxian(Hu-nan),Qingyang(Anhui),Nanning(Guangxi)and Fuling (Chongqing)during 2013 -2015.Seven va-rieties (lines)(TG5,TG6,NCO3,G59,BD0717,0501 and Zhongzhu No.1)were tested in the re-gional trial,which were provided by five institutes including Huazhong agricultural university.The study presented the statistic results of data of field trial and laboratory tests,and relevant sources of variation was analyzed emphatically using LSD which can impact fiber yield of testing varieties.The general evalu-ation and analysis were executed through a combination of agronomic trait,biological characteristics,re-sistance ability,fiber quality and the ripeness days.%本届国家苎麻新品种（系）区域试验于2013－2015年分别在江西宜春、四川达州、湖南长沙、湖北咸宁、湖南南县、安徽青阳、广西南宁及重庆涪陵共七省（区）的八个承试点进行，由华中农业大学等国内五家麻类育种科研单位提供的参试品种（系）TG5、TG6、NCO3、G59、BD0717、0501和中苎1号共计七个。本文对参试品种的田间试验、室内检测数据进行了统计分析，重点对影响参试品种纤维产量性状的相关变异来源进行了 LSD 法测验，并结合其主要农艺性状、生物学特性、抗逆性、纤维品质特性、生育期等方面进行了综合分析与评价。
