Abstract

Common bean was originated in México, and it is the most important protein source for millions of Mexicans, mainly those with low economic incomes. Grain yield of this crop is mainly affected by several fungal, bacterial and viral diseases. Among them, there are root rot diseases caused by the genera Macrophomina and Fusarium sp. Currently, some molecular biology tools such as DNA molecular markers are being used successfully to develop genetic maps where QTLs and major molecular markers are located, which are linked to genes that confer resistance to these fungi. The importance of the development of genetic maps is based on the fact that they are the previous step for Marker-Assisted Selection (MAS). In this paper we review the current overview about the studies of root rot diseases mapping of resistance genes in common beans caused by the fungi M. phaseolina and Fusarium sp. We also report on those successful cases where results are translated to future applications in MAS in order to increase the efficiency of common bean breeding to both fungi based on costs, working and effectiveness. Finally, we analyze the perspectives of biotechnological tools on common bean breeding with special emphasis in Mexico.
