SECURE aims to deliver a model for deployment of cultivars with resistance to
Leptosphaeria maculans (phoma stem canker/blackleg) to improve durability of resistance and minimise risk that the resistance will be overcome. The project has four main parts. Firstly, a life-cycle model for L. maculans has been developed and validated. Secondly, the fitness of virulent/avirulent
isolates of the pathogen is being investigated; the results indicate a fitness penalty resulting from loss of the avirulence function for at least two resistance genes. Genomic analysis of avirulence and virulence loci of the pathogen is also being done. In addition, two L.maculans avirulent alleles (AvrLm1 and AvrLm6) have been cloned. Thirdly, the effects of plant genetic background and
environmental factors on durability of resistance are being analysed in both field experiments at a number of sites across Europe and controlled environment experiments. Lastly, models have been developed to investigate the effects of different schemes for deployment of resistance on durability of resistance so that recommendations can be made for a sustainable strategy for managing the disease. Results are being disseminated using a website, scientific and popular publications and workshops.
