Pyramiding strategy for durable resistance to root-knot nematodes in Prunus Rootstocks

Root-knot nematodes (RKN) (Meloidogyne spp.) are extremely polyphagous pests with a high economic impact at the global scale. In stone fruit trees, three major dominant resistance (R) genes, Ma (plum),RMia (peach) and RMja (almond), have been identified and mapped in this objective. Pyramiding all three R genes opens the way to breeding rootstocks protected by at least two of them for a durable resistance...
