Abstract: 对全国21份野生三叶青种质资源进行生物学特性、扦插成活率与农艺性状考查,结果表明,不同种源三叶青生物学特性、扦插成活率与农艺性状存在显著差异,21份种源三叶青异地扦插平均成活率为69.7%,重庆与广西种源三叶青农艺性状表现优于浙江、江西、福建等种源;9个农艺性状简化为4个主成分,累计贡献率达90.6%;21个种源可以划分为4个类群,其中第Ⅰ类群与第Ⅱ类群三叶青农艺性状表现较好.通过叶片有无柔毛、茎形状与块根表面是否光滑等特性可初步区分浙江、湖南、湖北三叶青与广西、重庆等地三叶青;从农艺性状看,三叶青优良种质可优先在重庆、广西等种源中筛选;从供试的21个种源中,初步筛选出6个农艺性状表现良好的种源.
