摘要
对紫菀种质资源研究结果表明,各质量性状存在较大变异,以茎色、叶色、花色、瘦果颜色等变异最大;各数量性状亦存在较大变异,其中根茎重变异较大,变异系数达70.50%。紫菀各数量性状间存在一定的相关性,其中,紫菀根茎重与株高、茎粗、冠毛长呈极显著相关关系。因此,对紫菀进行资源的收集、评价和品种选育具有较大潜力和现实意义。
Germplasm research on Aster tataricus L.F.showed that much variation between quality and quantity characters.The most variations in quality characters were stem color, leaf color, flower color and achene color.Whereas the most variations in quantity characters were rhizome weight and the CV（coefficient of variance）is 70.50%.Correlativity exists in each quantity characters of Aster tataricus L.F., Correlativity between rhizome weight and plant length, stem width, pappus length were very significant.So, the resources of Aster tataricus L.F.on the collection, evaluation and breeding had greater potential and practical significance.
