Rice blast (caused by Magnaporthe grisea) is the most damaging fungal disease of rice. The use of resistant rice varieties is a cost effective method to control the disease and can be incorporated as a component of an integrated pest management (IPM) strategy, avoiding fungicide applications in such fragile areas. Determining the genetic and molecular basis of resistance in European varieties and including this knowledge in breeding programs is of primary importance to develop rice varieties durably resistant to blast. This project aims at using the appropriate genomic tools to identify the important genes for durable blast resistance and to start creating resistant varieties adapted for European growing conditions, through the combined efforts of different teams and using different methods.
