当归育种研究进展

Research Progress on Breeding of Angelica Sinensis

中药材基源植物优良品种是提升中药材质量的重要前提,当归为我国常用大宗中药材之一,人工栽培种植历史悠久,总结当归育种研究进展,为后期育种研究工作提供参考。文章对当归种质资源、细胞学、组织培养以及自然变异选择、杂交选育、辐射与倍性诱变等育种方面的研究内容进行了综述分析。文献分析表明,当归育种起步相对较晚,尽管近十余年来已经育成了一些品种,但在抗病品种和抗抽薹品种选育方面相对滞后,而生产中当归连作障碍凸显,病虫害逐年加重。因此,抗性育种将是当归今后育种的主要方向。

Good origin plant is an important prerequisite for improving the quality of Chinese herbs. Angelica sinensis,as one of the major Chinese medicinal materials,is commonly used in China; its artificial cultivation has a long history.This study summarized the research progress of the breeding of Angelica sinensis,providing reference for breeding research work in the future. This study reviewed germplasm resources,cytology,tissue culture,the breeding of natural variation selection,hybridization,radiation and ploidy mutation of Angelica sinensis. Literature analysis showed that the breeding of Angelica sinensis started relatively late,although it has made some varieties bred in the past ten years,the resistant varieties and bolting resistance breeding still lag behind; continuous cropping obstacle becomes prominent,plant diseases and insect pests increase year on year,therefore,resistance breeding will be the main research field in the future.
