Races of common bean (Phaseolus vulgaris, Fabaceae)
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.
Genetic Control of the Domestication Syndrome in Common Bean
The results suggest that domestication of common bean could have proceeded rapidly and that evolution can proceed through changes involving a few genes with large effect rather than through a gradual accumulation of changes coded by changes with small effects, and that adaptation to rapidly changing environmental conditions may involve genes withLarge phenotypic effects.
Genetic Diversity in Cultivated Common Bean: I. Allozymes
Confirmation that cultivated common bean (Phaseolus vulgaris L.) resulted from multiple domestications in Mesoamerica and in Andean South America was sought by analyzing patterns of diversity at nine polymorphic allozyme loci, all unlinked to the phaseolin locus.
Genetic Diversity in Cultivated Common Bean: II. Marker‐Based Analysis of Morphological and Agronomic Traits
This study examined the organization of diversity for morphological and agronomic characteristics in 306 landraces of cultivated common bean (Phaseolus vulgaris L.) from Latin America and its relationship with phaseolin seed protein and allozyme diversity of the landrace.
Broadening the Genetic Base of Common Bean Cultivars
- Shree P. Singh
- 1 November 2001
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.
Comparison of Sources and Lines Selected for Drought Resistance in Common Bean.
While new sources of drought resistance could be identified in races Durango and Jalisco, these drought resistant germplasm and selected lines derived from interracial and intergene pool populations should be utilized for improvement of drought Resistance in common bean.
Resistance to Common Bacterial Blight amongPhaseolus Species and Common Bean Improvement
Gene pyramiding produced lines with high CBB resistance, and is thus, a suitable method for developing CBB-resistant cultivars of different market classes.
Breeding Common Bean for Resistance to Diseases: A Review
The objectives were to describe major bean disease problems in the Americas and review progress achieved in breeding for resistance and describe strategies to integrate genetic improvement for resistance to multiple diseases with cultivar development.

Drought resistant genotypes should be used for determining irrigation frequency,amount ofwatertobe applied, andMechanism sofresistance and for identifying, mapping, and pyramiding favorable genes for dryland and irrigation-assisted sustainable production systems.
