Resistance to <i>P. infestans</i> isolates in <i>Solanum</i> species.

Wild Solanum accessions from diverse taxonomic series [16]–[18] were retrieved from the BGRC1 or CGN2 genebanks, and assessed for resistance to the aggressive P. infestans isolates 90128, IPO-C and 89148-09. R3a-resistant Desiree [41] and susceptible potato cultivar Bintje and breeding clone RH89-039-16 were included as controls. 1BGRC, Braunschweig Genetic Resource Center (BGRC) 2CGN, the Center for Genetic Resources, The Netherlands (CGN, http://www.cgn.wur.nl/uk/)
