Interpretive Summary:

Technical Abstract: Angular leaf spot is one of the most destructive diseases of common bean in Latin America and Africa. Genetic resistance is the most cost-effective strategy to manage the ALS disease. During the Common Bean Disease Workshop on Angular Leaf Spot in Skukuza, South Africa (July 2015), a work group was established to review the progress in genetic analysis and breeding for ALS resistance. To date, five resistance genes have been named and mapped on the genome of comma bean. These genes are: Phg-1 present on bean AND 227 and located on chromosome Pv01; Phg-2 present on Mexico 54 and its allele Phg-22 present on BAT 332, both located on chromosome Pv08; Phg-3 present on Bean Ouro Negro and located on chromosome Pv-04; Phg-4 present on bean G 5686 and located on chromosome Pv04; Phg-5 on bean CAL 143 and it allele Phg-52 on bean G 5686 and both located on chromosome Pv10. This information is of value to breeders and geneticists of common bean.
