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...

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...

Pathogenic variation in, sources of, and breeding for resistance to Phaeoisariopsis griseola causing angular leaf spot in common bean
A total of 18 bean var. with different degrees of rust resistance in the field were subjected to 4 treatments, to obtain high severity of Uromyces phaseoli under low RH. Treatments were (1) greenhouse inoculation, with optimum temp. and RH for disease development, (2) field inoculation in infecti...
