Enhanced understanding of anthracnose resistance in Michigan Dark Red Kidney common bean cultivar

Anthracnose, caused by the fungus Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi Cavara, is a major disease affecting common bean (Phaseolus vulgaris L.), potentially causing yield losses of up to 100%. Utilizing resistant cultivars most effective approach for control. This study aimed characterize genetic resistance two cultivars, TU Michigan Dark Red Kidney (MDRK), anthracnose. Inheritance tests were performed on F2:3 families from (R) × AND 277 (S) cross using C. race 3, crosses Kaboon Perry Marrow inoculated with 39. Inoculation three races showed that MDRK carried allele Co-1 locus. However, inoculation 1545 revealed MDRK's this conditioned dominant genes (Co-1 Pv01 another Pv04). Segregation results inheritance cultivar fitted 1RR:2RS:1SS ratio, indicating presence single gene in cultivar. Both Mesoamerican Andean represent valuable sources can be incorporated into breeding programs enhance resistance.
