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...

Mahuku, George S.Iglesias Garcia, AMJara, Carlos E.[Genetics of angular leaf spot resistance in the Andean common bean accession G5686 and identification of markers linked to the resistance genes]Genetics of angular leaf spot resistance in the Andean common bean accession G5686 and identification of markers linked to the resistance genes

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...


Mahuku, George S.Jara, Carlos E.Cuasquer, Juan B.Castellanos, G.[Genetic variability within Phaeoisariopsis griseola from Central America and its implications for resistance breeding of common bean]Genetic variability within Phaeoisariopsis griseola from Central America and its implications for resistance breeding of common bean

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...


Namayanja, ARBuruchara, Robin A.Mahuku, George S.Rubaihayo, P.R.Kimani, P.M.Mayanja, S.Eyedu, H[Inheritance of resistance to angular leaf spot in common bean and validation of the utility of resistance linked markers for marker assisted selection out side the mapping population]Inheritance of resistance to angular leaf spot in common bean and validation of the utility of resistance linked markers for marker assisted selection out side the mapping population
Mahuku, George S.Henriquez Naranjo, MAMontoya Jaramillo, CJara, Carlos E.Terán Santofimio, HenryBeebe, Stephen E.[Inheritance and development of molecular markers linked to angular leaf spot resistance genes in the common bean accession G10909]Inheritance and development of molecular markers linked to angular leaf spot resistance genes in the common bean accession G10909

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...


Mahuku, George S.Henriquez Naranjo, MAMuñoz, J.Buruchara, Robin A.[Molecular markers dispute the existence of the Afro-Andean group of the bean angular leaf spot pathogen, Phaeoisariopsis griseola]Molecular markers dispute the existence of the Afro-Andean group of the bean angular leaf spot pathogen, Phaeoisariopsis griseola

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

Use of genetic resistance is the most practical and economic way to manage anthracnose of common bean. Colletotrichum lindemuthianum, the causal agent of bean anthracnose, is a highly variabile pathogen, and there are no host resistance genes that are effective against all known races of the path...

Diversidad de razas de Colletotrichum lindemuthianum en Antioquía y evaluación de germoplasma de frijol crema-rojo por resistencia a antracnosis. Para verificar si la composición de razas en el Oriente de Antioquía se caracterizaron 15 aislamientos de C. lindemuthianum, usando 12 variedades difer...
