Twenty-eight bean genotypes and lines from the Embrapa Arroz e Feijão breeding program, and other research institutions, were evaluated for angular leaf spot reaction to eight pathotypes of Phaeoisariopsis griseola. Genotypes were inoculated 14-16 days after sowing by spraying an inoculum suspension containing 2.0 x 10(4) spores mL-1. Symptoms were evaluated 14-18 days after inoculation according to a 1-9 scale where disease ratings from 1 to 3 were considered resistant and 4 to 9 as susceptible. Genotypes 'Ouro Negro' and 'LM 202202530' were resistant to eight and seven pathotypes, respectively. Cultivar BRS Requinte was resistant to five pathotypes and cultivars BRS Pontal and Cornell 49-242 were resistant to only four pathotypes.
