A poster presented at the 2012 Global Pulse Researchers Meeting, Kigali, Rwanda- “Transforming Grain-Legume Systems to Enhance Nutrition and Livelihoods”. Abstract: The objectives of this study was to identify sources of resistance to angular leaf spot (ALS) in bean cultivars from Angola. Inoculation of Phaeoisariopsis griseola was carried out in two experiments using an isolate from Isabela, Puerto Rico. Bean plants were inoculated with an atomizer using a 1 x 105 conidia/ml of P. griseola and evaluated 35 and 20 days after inoculation using the CIAT 1-9 scale. The isolate of P. griseola from Isabela infected both Mesoamerican and Andean bean lines. In the first experiment, G05685 (Andean) and ‘Flor de Mayo’ (Mesoamerican) were resistant to ALS. ‘Montcalm’, ‘Amendoin’ and Angolan cultivars Catarina and Canario had susceptible reactions. In the second experiment ‘Ermelinda’, and Fernantdo, were susceptible to ALS (5). Resistant cultivars were Pedro, Ervilha, Calembe, Tabe and Calongupa.
