Patterns of variation in cultivated common bean ( Phaseolus vulgaris , Fabaceae)
TLDR
Most of the variation in the snap or stringless bean appears to be of relatively recent origin; it was greatest among cultivars from China, Europe, and the United States.Abstract:
More than 18,000 accessions of common bean (Thaseolus vulgaris, Fabaceae) from the Centro Internacional de Agricultura Tropical (CIAT) germplasm bank were examined at two locations in Colombia. A large variation in cultivated dry bean was found among accessions from primary centers of domestication in Middle and South America. For some bean types, such as medium- and large-seeded white, variation was greater among germplasm from western Asia (Turkey) and Europe (Portugal, Spain, Greece, France, Italy, and Bulgaria). Based on growth habit, on seed, pod, and leaf characteristics, and on ecological regions of adaptation, dry-bean germplasm was divided into a total of six gene pools from Middle American and four gene pools from South American centers of domestication. Most of the variation in the snap or stringless bean appears to be of relatively recent origin; it was greatest among cultivars from China, Europe, and the United States. These could be grouped into two additional gene pools. A strategy for breeding and transfer of genes across gene pools is also discussed.read more

Races of common bean (Phaseolus vulgaris, Fabaceae)
TL;DR: Multivariate statistical analyses of morphological, agronomic, and molecular data, as well as other available information on Latin American landraces representing various geographical and ecological regions of their primary centers of domestications in the Americas, reveal the existence of two major groups of germplasm: Middle American and Andean South American, which could be further divided into six races.

Broadening the Genetic Base of Common Bean Cultivars
TL;DR: The origin, domestication, and organization of genetic diversity in Phaseolus beans is reviewed, production problems and traits deficient in the common bean (P. vulgaris L.) cultivars are highlighted, sources of useful gemplasm are cited, and progress achieved is reviewed.

Towards an integrated linkage map of common bean : 1. Development of genomic DNA probes and levels of restriction fragment length polymorphism.
TL;DR: Two genomic libraries were established to provide markers to develop an integrated map combining molecular markers and genes for qualitative and quantitative morpho-agronomic traits in common bean, and a positive correlation was observed between the average size of hybridizing restriction fragments and the frequency of polymorphism detected by each restriction enzyme.

Agricultural Origins: Centers and Noncenters
TL;DR: The theory that agriculture originated independently in three different areas and that, in each case, there was a system composed of a center of origin and a noncenter, in which activities of domestication were dispersed over a span of 5,000 to 10,000 kilometers is proposed.

Phaseolin-protein Variability in Wild Forms and Landraces of the Common Bean (Phaseolus vulgaris ): Evidence for Multiple Centers of Domestication
TL;DR: The authors' data favor 2 primary areas of domestication, one in Middle America leading to small-seeded cultivars with ‘S’ phaseolin patterns and the other in the Andes giving rise to large-seeding cultivarsWith ‘T’ (and possibly ‘C,’ ‘H,” and ‘A’) phaseolinpatterns.

The origin, evolution, cultivation, dissemination, and diversification of Asian and African rices
TL;DR: Both the African and Asian rices are still undergoing evolutionary changes at habitats where the wild, weed, and cultivated races co-exist, largely due to cultivators' preferences, socio-religious traditions, and population pressure.
