A KASP marker for the Potato Late Blight Resistance Gene RB/Rpi-blb1
The resistance gene RB, aka Rpi-blb1, is effective against most strains of the potato late blight pathogen, P. infestans. Until now, potato breeders have used a SCAR marker to screen for RB. Our objective was to design and validate a KASP marker, which has advantages for high-throughput screening.
