Genetics and mapping of a new anthracnose resistance locus in Andean common bean Paloma.

ABSTRACT:

Background

The Andean cultivar Paloma is resistant to Mesoamerican and Andean races of Colletotrichum lindemuthianum, the fungal pathogen that causes the destructive anthracnose disease in common bean. Remarkably, Paloma is resistant to Mesoamerican races 2047 and 3481, which are among the most virulent races of the anthracnose pathogen. Most genes conferring anthracnose resistance in common bean are overcome by these races. The genetic mapping and the relationship between the resistant Co-Pa gene of Paloma and previously characterized anthracnose resistance genes can be a great contribution for breeding programs.

Results

The inheritance of resistance studies for Paloma was performed in F₂ population from the cross Paloma (resistant) × Cornell 49-242 (susceptible)
