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...


Jara, Carlos E.Castellanos, G.Mahuku, George S.[Estado actual y proyección de la investigación relacionada con mancha angular del frijol (Phaeoisariopsis griseola)]Estado actual y proyección de la investigación relacionada con mancha angular del frijol (Phaeoisariopsis griseola)

A polymerase chain reaction approach using degenerate primers that targeted the conserved domains of cloned plant disease resistance genes (R genes) was used to isolate a set of 15 resistance gene analogs (RGAs) from common bean (Phaseolus vulgaris). Eight different classes of RGAs were obtained ...


López, C.E.Acosta, I.F.Jara, Carlos E.Pedraza García, FabioGaitán Solís, ElianaGallego Sánchez, Gerardo J.Beebe, Stephen E.Tohme, Joseph M.[Identifying resistance gene analogs associated with resistances to different pathogens in common beans]Identifying resistance gene analogs associated with resistances to different pathogens in common beans

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...


Pastor Corrales, Marcial A.Jara, Carlos E.Singh, Shree P.[Pathogenic variation in, sources of, and breeding for resistance to Phaeoisariopsis griseola causing angular leaf spot in common bean]Pathogenic variation in, sources of, and breeding for resistance to Phaeoisariopsis griseola causing angular leaf spot in common bean

It is widely accepted that two major gene pools exist in cultivatedcommon bean, one Middle American and one Andean. Recently another gene pool,designated as North Andean and a fourth group (not considered to be adistinct gene pool) have been reported by the senior author and hiscolleagues. Many o...


Islam, F.M.A.Basford, KEJara, Carlos E.Redden, RJBeebe, Stephen E.[Seed compositional and disease resistance differences among gene pools in cultivated common bean]Seed compositional and disease resistance differences among gene pools in cultivated common bean

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...


Mahuku, George S.Jara, Carlos E.Cajiao V., César HernandoBeebe, Stephen E.[Sources of resistance to angular leaf spot (Phaeoisariopsis griseola) in common bean core collection, wild Phaseolus vulgaris and secondary gene pool]Sources of resistance to angular leaf spot (Phaeoisariopsis griseola) in common bean core collection, wild Phaseolus vulgaris and secondary gene pool

Angular leaf spot (ALS), caused by the fungus Phaeoisariopsis griseola (Sacc.) Ferr., is one of the most important diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical bean producing areas. The common bean accession G 10474 has been widely resistant to P. griseola, includin...
