Phaseolus vulgaris line A193 has been shown to be widely resistant Colletotrichum lindemuthianum, including race 1472, one of the most virulent races C. lindemuthianum characterized. Resistance 1472 in P. was investigated segregating F 2 and 2.3 populations from a cross between Flor de Mayo Bajio (a commercial cultivar highly susceptible lindemuthianum). determined conditioned by single dominant gene. Inoculation crosses cultivars Michigan Dark Red Kidney Perry Marrow with suggest that resistance is Co-1 × 2, demonstrated also gene distinct or Kidney. Three AFLP markers (ECAG/MACC-1, EACA/MAGA-2, EAGG/MAAC-8) linked repulsion locus were identified screening population 314 random amplified polymorphic DNA, fragment length polymorphism, restriction polymorphism markers. The two closely should useful marker-assisted selection for Co-1.
