Coix lacryma-jobi Linn.has a long cultivation history as a minor crop in China,however many problems like unclear origin,chaos of varieties,loss and inaccurate use of germplasm resources exist in its research and production because we lack systematic study.In recent years, the importance of coix has been realized after the extract of Coix lacryma-jobi Linn.can help treat and prevent cancer.A superb opportunity has arisen with the rapid development of biotechnology especially the deep-sequencing technique.Thus we presented here the current status of origin and evolution,classification,cytology and molecular biology progress of coix,analyzed the ploidy of coix and the phylogenetic relationship with zea mays,sorghum and so on from cytology aspect,then based on the molecular biology,analyzed the important significance of DNA molecular marker,genetic mapping and gene library in the research of identification of the species phylogenetic relationship and genetic breeding,which could provide useful informations for further coix research.
