摘　　要：广义菊属共有30余属,其中许多具有抗逆性较强的种类。为了进行菊属植物的抗旱育种,须广泛收集抗旱菊属的近源种属资源作为育种材料和杂交亲本。通过对华北、内蒙和西北部分地区的野生广义菊属资源进行调查,共收集到了广义菊属的15个种。并对收集种进行了初步的引种和评价,为进行广义菊属资源的调查研究和充分利用广义菊属的抗旱野生资源提供了基础和参考。In order to improve drought resistance of Chrysanthemum by using cross-breeding method,an investigation on seven mountains in North China,Inner Mongolia and Northwest areas was conducted to collect Chrysanthemum wild natural resources as breeding materials.Samples from fifteen species were collected in total,including：Chrysanthemum mongolicum,Ajania fruticulosa,Chrysanthemum indicum,Hippolytia alashanensis,Opisthopappus taihangensis,Chrysanthemum chanetii,etc.Collected species were introduced to Beijing and a comprehensive evaluation was made on their drought resistance and landscape applications.This paper has provided foundations for further investigation and research on Chrysanthemum wild resources with high drought resistance.
