Chloroplast DNA polymorphisms were studied by PCR sequencing and PCR-restriction fragment length polymorphism in 165 accessions of domesticated landraces of common bean from Latin America and the USA, 23 accessions of weedy beans, and 134 accessions of wild beans covering the entire geographic ra...
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...
The wild common bean (Phaseolus vulgaris) is widely but discontinuously distributed from northern Mexico to northern Argentina on both sides of the Isthmus of Panama. Little is known on how the species has reached its current disjunct distribution. In this research, chloroplast DNA polymorphisms ...
During germplasm explorations carried out in Peru and Colombia, interbreeding complexes of wild and cultivated common bean were observed in both countries, eight in Apurimac and Cusco departments of Peru and eight in Cundinamarca and Boyacá departments of Colombia. The existence of complexes was ...
