    摘要:

    旨在利用形态指标、农艺指标和品质性状指标探讨引进紫花苜蓿( M.sativa.)种质资源遗传多样性,为紫花苜蓿品种改良和选择亲本提供科学依据。研究了不同地理来源的75份紫花苜蓿种质资源的21项指标,利用主成分分析和聚类方法,了解其多样性。结果表明:不同紫花苜蓿种质的各特征存在广泛变异,农艺性状变异最大,随后是形态性状和品质性状;主成分分析结果显示前八个主成分累计贡献率达到82.77%,其中茎秆干重、叶干重、单株鲜重、单株干重4个性状是造成紫花苜蓿种质表型差异的主要因素;以21个性状为基础的聚类分析将所研究的75份种质材料分为5类。

    Abstract:

    The objective of this research is to explore the genetic diversity of Alfalfa germplasm resources by Phenotypic traits and Quality Characteristics provide basis for variety improvement and parent choice. 21 indexes of 75 alfalfa sativa accessions from different geographical origins were studied. The Phenotypic traits and Quality Characteristics were analyzed by principal component analysis and cluster analysis. The results showed that there were extensive variations in Phenotypic traits and Quality characteristics in different alfalfa accessions. The most significant variance was agronomic traits, followed by morphological characters and Quality Characteristics;Principal component analysis showed that The additive contributing rate of first eight principal components was 82.77%,four major discriminating characteristics were selected to reflect the comprehensive agronomic characters.Stem dry weight,leaf dry weight,plant fresh weight and plant dry weight were the main factors which produced morphological variation of 75 wild alfalfa accessions. Based on the 21 indexes, cluster analysis showed that all 75 accessions of alfalfa were divided into 5 groups.
