摘　　要：远缘杂交和基因工程是种质创新的主要途径。本研究总结了菊花的16个近缘属、17个近缘种种质,依据前人的杂交实验结果,分析野生种质与菊花亲缘关系的远近,发现亚菊属、春黄菊属和小滨菊属等6个属与菊花的亲和性较强,野菊、紫花野菊、毛华菊、甘菊与菊花之间的亲缘关系较近,有6个属和11个种的种质与菊花之间的亲缘关系还不明确。阐述菊花基因工程育种在观赏性状和抗性性状改良方面的成果,建议开展更广泛的杂交试验和基因发掘,改进远缘杂交和基因工程的技术和模式,并搭建高效育种平台,以提升种质创新的效率。Distant hybridization and genetic engineering are main approaches to germplasm innovation.In this study,16 related genera and 17 related species of chrysanthemum were summarized.According to the results of previous hybrid experiments,the genetic relationship between wild germplasm and chrysanthemum was analyzed.It was found that six genera such as Ajania,Anthemis and Leucanthemella had strong affinity with Chrysanthemum×morifolium,and the genetic relationship among C.indicum,C.zawadskii,C.vestitum,C.lavandulifolium and C.morifolium was close.The genetic relationship between germplasm of 6 genera and 11 species and C.morifolium was not clear.we also summarized the achievements of chrysanthemum genetic engineering breeding in the improvement of ornamental and resistance traits,and suggested that more extensive hybridization experiments and gene discovery should be carried out,the technology and mode of distant hybridization and genetic engineering should be improved,and an efficient breeding platform should be built to improve the efficiency of Germplasm Innovation.
