Inheritance of resistance to angular leaf spot (ALS) disease caused by Phaeoisariopsis griseola (Sacc.) Ferr was investigated in two common bean cultivars, Mexico 54 and BAT 332. Both Andean and Mesoamerican backgrounds were used to determine the stability of the resistance gene in each of the tw...

En el presente trabajo se compara la diversidad genética de 33 aislamientos de P. griseola de Africa con 52 de América Latina utilizando tres marcadores de variabilidad: virulencia, isoenzimas y la técnica molecular RAPDs. Los tres marcadores separaron los aislamientos tanto de Africa como de Amé...

Coevolution of the angular leaf spot pathogen, Phaeoisariopsis griseola, with its common bean host has been demonstrated, and P. griseola isolates have been divided into Andean and Mesoamerican groups that correspond to defined bean gene pools. Recent characterization of P. griseola isolates from...
