Mahuku, George S.Jara, Carlos E.Terán Santofimio, HenryBeebe, Stephen E.[Inheritance of angular leaf spot resistance in selected common bean genotypes]Inheritance of angular leaf spot resistance in selected common bean genotypes

La mancha angular del frijol común, Phaseolus vulgaris L., es causada por el hongo Phaeoisariopsis griseola (Sacc.) Ferraris. Esta enferme dad esta ampliamente distribuida en las zonas tropicales y subtropica les y afecta la calidad de las vainas, reduce el peso de la semilla y puede causar eleva...

The genetic and virulence variability of 112 isolates of Phaeoisariopsis griseola, collected from various locations in Central America, were studied using seven random amplified polymorphic DNA (RAPD) primers and 12 common-bean differential genotypes. Broad molecular diversity (H = 0·92) among is...

If we are to breed common bean (Phaseolus vulgaris L.) for durable resistance to diseases, we must understand pathogenic variation and find sources of resistance. Our first objective was to determine the patterns of pathogenic variation found among isolates of Phaeoisariopsis griseola (PG), the f...

Angular leaf spot (ALS) is one of the most devastating diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical countries. The causal fungus, Phaeoisariopsis griseola(Sacc.) Ferr. is highly variable and a diverse source of resistance genes is required to manage this disease. We...
