Abstract: Rice blast disease was one of the most destructive diseases in rice growing region worldwide. The use of resistance cultivars was considered as the most economic and effective method for blast control. Identification and utilization of resistance genes were recognized the basis and key factors for breeding resistance cultivars. In this paper, genetics, mapping, cloning and breeding application of the genes resisting to blast were summarized, and the newest progress of broad spectrum resistance genes and recessive resistance genes were introduced. Nearly half of the resistance genes had been identified in F2 populations. Currently, over 85 dominant resistance genes and 350 quantitative trait loci (QTLs) had been identified in a variety of rice resources. Twenty dominant resistance genes and two QTLs had been cloned and characterized by a map-based cloning approach. The mapping and cloning of such resistance genes were the basis for a marker-aided-selection strategy applied in rice blast resistance breeding programs. Finally, with the work practice of rice blast resistance genetics, the problems of rice blast resistance genes were analyzed and prospected. As more all types of blast resistance genes had been applied in production, the damage of blast to rice would be controlled effectively at last.
