Monitoring the Dutch Phytophthora infestans population for virulence against new R-genes

New possibilities offered by marker assisted breeding and GMO breeding have sparked renewed international efforts to breed for durable potato late blight resistance. Phytophthora infestans is however known for its adaptability, a trait confirmed by recent discoveries on the structure of the P. infestans genome. One of the possibilities to enhance the durability of newly introduced host resistance is to monitor the pathogen population for virulence to new R genes, prior to - and after their introduction. The late blight control strategy should be adapted accordingly. The Dutch P. infestans popu... Mehr ...
