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...

Pod harvest index as a selection criterion to improve drought resistance in white pea bean
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...

Genetic diversity and relation between common bean angular leaf spot fungus isolates from Africa and South America: genetic improvement implications
Aluminium (Al) toxicity limits common bean productivity in acid soil regions of the tropics. To improve Al resistance of common bean, Al-sensitive Phaseolus vulgaris (SER16) was crossed to Al-resistant P. coccineus (G35346-3Q) to create 94 F5:6 recombinant inbred lines (RILs) of the pedigree SER1...
