摘　　要：【目的和方法】观察研究11份白三叶材料的生育期、形态特征、产量等。【结果】供试材料在外部形态性状上表现出较大的差异,具有丰富的形态多样性。材料5、6、10、11植株高大、叶片较大、产量高,生长表现较好;材料89、植株低矮、叶片较小、绿色期短、产量低,生长表现较差;其余材料表现适中。对主要外部形态性状进行聚类分析,可将11份白三叶材料种质类群聚分为4类。【结论】筛选出形态差异较大的3份材料,可作为绿化、生态保护和牧草型物种选育的材料。[ Objective and Method] Eleven materials were primarily studied on their morphological characters, growth stages,production etc. [Result]The results showed that the variance of white clover was great.Among them, 5,6, 10, 11 had high plant big leaves, high yield, fair growth expression. The material 8,9 had low plant, small leaves, short green period, low yield and relatively poor growth expression , others were in the middle;Based on the cluster analysis of main morphological traits., all the materials were divided into four types. [ Conclusion ] Three materials were screened, which could serve as green, ecological protection and forage species.
