Organization of Genes Conferring Resistance to Anthracnose in Common Bean - Translational Genomics for Crop Breeding: Biotic Stress - page 164

Fig. 9.2. Linkage groups showing anthracnose race-specific resistance genes directly mapped using different common bean
genotypes. Specific resistance genes are named considering the relative position of seven gene clusters ( Co-1, Co-2, Co-3,
Co-4, Co-5, Co-13 ,and Co-u ), the isolate or race of C. lindemuthianum , and bean genotype used in the genetic analysis to
describe the corresponding resistance gene(s) are indicated by superscript. For a color version of this figure, please refer to the

aF 2:3 population derived from the cross TU
x MDRK (Campa et al. 2009). The OF10 530
fragment was previously linked to the anthrac-
nose resistance locus Co-1 in the F 2:3 population
derived from the cross between the near-isogenic
lines N85006 S and N85006 R (Young and Kelly
1997a) and later mapped to Pv01 (Rodrıguez-
Suarez et al. 2007; Geffroy et al. 2008; Vallejo
and Kelly 2008). The Co-1 gene first described
as the A factor in the cultivar Wells' Red Kid-
ney (Burkholder 1918; McRostie 1919). It was
assumed that the A gene is the same gene present
in the differential cultivar MDRK (Melotto et al.

Race-specific Co- resistance genes from Andean
bean genotypes MDRK, JaloEEP558, Kaboon,
Andecha, Xana, and AND277 were mapped to
Pv01 (Figure 9.2).
In the differential cultivar MDRK, a gene con-
ferring specific resistance to race 1545, linked
to OF10 530 marker, was mapped to Pv01 using
