Abstract: | This paper reports on a debate on intriguing propositions relating to the scientific, agronomic, societal and economic impact
of the BIOEXPLOIT project, focusing on late blight resistance in potato. It discusses (i) whether identifying pathogen effectors
will facilitate selecting durable R genes, (ii) whether breeding for durable late blight resistance requires deploying Rpi (for Resistance to P
hytophthora
i
nfestans) genes, (iii) whether breeding strategies and cultural practices determine the durability of new resistance genes, (iv) whether
marker-assisted breeding for Phytophthora infestans resistance is already in the stage of adoption, (v) to what extent genetically-modified organism technology can advance realizing
late-blight resistant potato cultivars, and (vi) whether modifying R genes will result in novel broad spectrum resistance. |
