The origin of 5 Phaseolus species cultivated in America (P. vulgaris, P. lunatus, P. coccineus, P. acutifolius, and P. polyanthus) is discussed within the context of a broader theory of the origin of this genus, for which 3 centers of origin may be defined: Mesoamerica, the northern and southern ...

A field experiment was conducted at Department of Agricultural Research in Sebele in the 2012 to 2013 season using nine accessions that were sourced from the National Plant Genetic Resource Centre (NPGRC), Gaborone, Botswana. Multivariate statistical procedures such as clusters and principal comp...

Different aspects on the history, screening, and domestication effect on the evolution of the bean species are discussed, based on the concept of species domestication. Data are examined on plant systematics and geography, etnological botany, biochemistry, arqueology, and genetics of the crop. Th...

Congruity and recurrent backcross interspecific hybrids between common bean (Phaseolus vulgaris L.) and tepary bean (P. acutifolius A. Gray) were compared for the amount of introgression occurring between genomes by amplified fragment length polymorphism (AFLP) markers. A total of 60 genotypes we...
