Crop wild relatives that have experienced multiple and independent domestication events provide an excellent model for understanding adaptation processes in crop populations and a first and relevant aspect to investigate is the geographic origin of landraces. The aim of this research was to estab...

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...
