摘要：

为了对短葶山麦冬栽培种质进行评价和分析，广泛收集短葶山麦冬道地药材产区栽培种质45份，调查其主要形态性状和经济性状。以经济性状为选育目标通过聚类分析筛选出优良种质。结果表明，分支数、根数、单株块根数、多块根根数、叶长、叶宽、叶脉数、块根长、块根直径等9个主要形态性状和单株产量、多糖含量和皂苷含量3个经济性状差异显著。45份短葶山麦冬种质可以分为5个类群，其中第IV和V类群综合性状表现优良。通过对短葶山麦冬栽培种质广泛收集与评价筛选出3份优良品种。

Abstract:

To appraise and analyze the quality of L. muscar germplasm resources. Cultivated Liriope muscar germplasm were widely collected in genuine medicinal materials production area. All of those main morphological characters and economic traits were investigated. The excellent germplasm with good economic traits were selected based on cluster analysis. 45 germplasm resources of L. muscar were collected. There were significant differences in 9 main morphological characters, including branch number, root number, the single root tuber, the multiple root tuber, leaf length, leaf width, the vien number, the root tuber length, the root tuber diameter. significant differences were also in 3 main economic traits, including yield per plant, polysaccharide content and total saponin content. 45 germplasm resources can be divided into 5 groups. Group IV and V were with excellent comprehensive characters. 3 good germplasm were selected based on widely collected and appraised of L. muscar.
