普通菜豆抗炭疽病基因鉴定与分子标记

菜豆炭疽病是世界菜豆生产中的主要病害之一，使幕豆产量和品质受到严重影响，对抗炭疽病基因的研究可以为培育抗炭疽病品种奠定基础。幕豆炭疽病病菌生理分化比较复杂，由于菜豆品种的抗病性和地域不同，菜豆炭疽菌的致病性分化不同。10个已知抗炭疽病基因中，9个基因（Co-1、Co-2、Co-3／Co-9、Co-4^2、Co-5、Co-6、Co-7、Co-10）已被确认为独立显性基因，其中Co-3／Co-9是等位基因；Co-1、Co-4和Co-9存在等位基因，co-8为隐性基因。除Co-5、Co-7和co-8三个基因还没有被定位外，其他基因被定位在不同的连锁群上。

Identification and Molecular Marker for the Resistance Genes to Anthracnose in Common Bean

Anthracnose(Colletotrichum lindemuthianum)is regarded as one of the most devastating diseases of common bean throughout the world.It causes greater losses to the production and quality of common bean.The study on the gene resistance to anthracnose can supply a foundation for resistance breeding.Gene resistance to anthracnose in common bean is Co-1 to Co-10 among which nine are independent and Co-3/Co-9 is allelic.Except the recessive co-8 gene,all other nine are dominant genes and multiple alleles exist at Co-1,Co-4 and Co-9 loci.Except loci Co-5,Co-7 and co-8,all other genes are mapped to different linkage groups.
