Association between RAPD marker OPAS13950C and anthracnose resistance allele Co-43 of common bean

Type: article
Abstract: 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-43 and Co-9 in PI207262. Markers OPY20s35c and OPAS13 5. have been identified as tightly linked to Co-4 gene of cultivar TO and Co-4o allele of cultivar G 2333 and Selection 1308, respectively. Potentially these markers could be helpful in the selection of plants harboring the Co-4o allele derived from PI 207262. Main goals of the present study were to test markers OPY20s30c and OPAS1 39509c to identify the most promising molecular marker linked to the Co-43 allele and determine the genetic distance between each marker and the allele. We observed that the RAPD molecular marker OPAS13,,s linked at 3.5 cM from Co-4. This is the first study that reports a molecular marker associated to Co-4% anthracnose retance allele of the common bean cultivar PI 207262.
