Abstract
Potato crops world-wide suffer severe losses to Phytopthora infestans (late blight). The full repertoire of resistance genes to P. infestans (Rpi genes) in wild Solanum species has been difficult to breed into productive varieties. However, establishing progeny that segregate for P. infestans resistance in interspecific crosses should facilitate Rpi gene isolation prior to transformation into cultivated varieties. Isolation of multiple Rpi genes, coupled with Avr gene isolation from P. infestans in other labs, will permit investigation of molecular mechanisms of R/Avr recognition between plants and oomycete parasites. In wild species, balancing polymorphism contributes to disease tolerance; deploying multiple Rpi genes will permit testing the use of Rpi gene mixtures for more durable P. infestans resistance.
