Conteúdo: | Cultivar PI 207262 is an important source of resistance to common bean anthracnose caused by the fungus Colletotrichum lindemuthianum. Previous studies identified the presence of anthracnose resistance genes Co-4 3 and Co-9 in PI 207262. Markers OPY20830C and OPAS13950C have been identified as tightly linked to Co-4 gene of cultivar TO and Co-42 allele of cultivar G 2333 and Selection 1308, respectively. Potentially these markers could be helpful in the selection of plants harboring the Co-43 allele derived from PI 207262. Main goals of the present study were to test markers OPY20830C and OPAS13950C to identify the most promising molecular marker linked to the Co-4 3 allele and determine the genetic distance between each marker and the allele. We observed that the RAPD molecular marker OPAS13950C is linked at 3.5 cM from Co-43. This is the first study that reports a molecular marker associated to Co-4 3 anthracnose resistance allele of the common bean cultivar PI 207262.
