Stacking three late blight resistance genes from wild species directly into African highland potato varieties confers complete field resistance to local blight races by Ghislain, M., Byarugaba, A.A., Magembe, E., Njoroge, A.W., Rivera, C., Roman, M.L., Tovar, J.C., Gamboa, S., Forbes, G., Kreuze, Jan F., Barekye, A., Kiggundu, A.

“…Considered responsible for one million deaths in Ireland and widespread famine in the European continent during the 1840s, late blight, caused by Phytophthora infestans, remains the most devastating disease of potato (Solanum tuberosum L.) with about 15%–30% annual yield loss in sub‐Saharan Africa, affecting mainly smallholder farmers. We show here that the transfer of three resistance (R) genes from wild relatives [RB, Rpi‐blb2 from Solanum bulbocastanum and Rpi‐vnt1.1 from S. venturii] into potato provided complete resistance in the field over several seasons. …”
