中文摘要：

以新疆7个生态区分布的45个居群棱叶蒜为材料,对其数量性状进行相关性、主成分与聚类分析,并利用隶属函数法对其性状进行综合评价。结果表明：根系与鳞茎、花序;须根与花葶;叶与花序;花葶与株芽;花序与花梗、小花数目以及花梗与小花大小及数目等性状之间达到极显著相关（P〈0.01）;花序与须根、鳞茎;叶与株芽等性状之间达到显著相关（P〈0.05）。主成分分析将棱叶蒜15个主要数量性状分为综合因子、株芽因子、鳞芽因子、根系因子、叶因子和单花因子,其累计贡献率为81.882%。在遗传距离为5时,将材料分为5大类群。阿尔泰山脉Ⅱ区分布的棱叶蒜隶属函数值最高,为0.418,是野生棱叶蒜重要分布地;15个性状中根系大小隶属函数值最高,为0.516,是人工驯化栽培和育种过程中的关键性状。

英文摘要：

45 population Allium caeruleum Pallas distributed in 7ecological zones,Xinjiang were used as materials,whose quantitative traits were analyzed correlatively,componentially and clusteringly,whose traits were appraised with subordinate function method.The results showed that the traits,size and number of root system and bulb,inflorescence,fibous.root and scape,leaf and inflorescence,scape and bulbil,inflorescence and stalk,spikelet number and stalk and spikelet achieved extremly significant correlation（P〈0.01）,the traits of inflorescence and fibous root,bulb;leaf and bulbil achieved significant correlation（P〈0.05）.Based on the principal component analysis,15 principal number traits of Allium caeruleum Pallas were divided into comprehensive factor,bulbil factor,bulblet factor,root system factor,leaf factor and single flower factor,whose cumulative contribution rate was 81.882%.When the genetic distance was 5,45 materials were divided into 5groups.The subordinate function value of Allium caeruleum Pallas distributed in area No.2of Altai Mountains range was the highest,which reached 0.418,and was an important population;The subordinate function value was the highest（0.516）which was the key trait in the process of artificial domestication cultivation and breeding.
