摘　　要：绿豆是亚洲国家重要的经济作物。绿豆基因组的研究工作已开展多年,至今已经发布了6张遗传连锁图谱,然而还未有一张图谱的连锁群数与绿豆(2n=2x=22,n=11)的染色体基数一致。近年来,豆科植物比较基因组学的研究成果,为绿豆遗传连锁图谱的发展提供了新的思路。通过将绿豆遗传连锁图与其他豆类连锁图比较发现,绿豆与小豆、豇豆、普通菜豆、大豆、藊豆以及豆科模式植物—蒺藜苜蓿的基因组间有不同程度的保守性,其中尤以绿豆与普通菜豆基因组间共线性水平高。本文分别从绿豆遗传连锁图谱构建、比较基因组作图以及抗豆象基因定位等方面进行了综述,以期为绿豆遗传研究工作者提供参考。Mungbean [Vigna radiata（L.）Wilczek]（2n=2x=22）is an important legume crop in Asia.Studies on mungbean genome have been reported and six sets of genetic linkage maps have been developed but the number of linkage groups of each set of map is not agreeable with the number of chromosomes in mungbean genome.Comparative mapping revealed various levels of macrosynteny between genomes of mungbean and other legumes including azuki bean,cowpea,common bean,soybean,lablab and medicago trunculata,while the greatest conservation were observed between mungbean and common bean.Genes mapping for bruchids resistance also have been reported in mungbean recently.This paper gives an overview of construction of mungbean genetic linkage maps,comparative genome mapping and gene mapping for bruchids resistance to assist genome reseach and molecular breeding in mungbean.
