Knowledge, access, and use of diversity available in cultivated and wild relatives are essential for broadening the genetic base of cultivars to sustain improvement. My objectives are to review briefly the origin, domestication, and organization of genetic diversity in Phaseolus beans, highlight production problems and traits deficient in the common bean (P. vulgaris L.) cultivars, cite sources of useful gemplasm, and review progress achieved in broadening the genetic base of cultivars. Phaseolus beans originated in the Americas. Only five species, P. acutifolius A. Gray, P. coccineus L., P. lunatus L., P. polyanthus Greenman, and P. vulgaris L. were domesticated. The interspecies diversity in relation to common bean is organized in primary, secondary, tertiary, and quaternary gene pools. Intraspecies diversity in common bean is separated into two major gene pools (Andean and Middle American). Cultivars are further divided into races, each with their distinguishing characteristics. Also, cultivars of dry seed and snap bean exist. Abiotic and biotic stresses limit common bean production. The genetic base of cultivars within market classes is narrow and inadequate level of resistance to common bacterial blight [caused by Xanthomonas campestris pv. phaseoli (Smith) Dye] and white mold [caused by Sclerotinia sclerotiorum (Lib) de Bary] exist in cultivars. High levels of resistance to these and other desirable traits exist in the relatives and gene pools of P. vulgaris Early maturity, adaptation to higher latitude, upright plant type, high pod quality and seed yield, and resistance to Bean common mosaic virus (a potyvirus) and/or rust [caused by Uromyces appendiculatus (Pers.:Pers.) Unger] have been bred into cultivars. However, most of the genetic variability available in the common bean races, gene pools, and wild relatives remains to be utilized. To maximize and sustain bean production, high yielding, high quality cultivars that are less dependent on water, fertilizer, pesticides, and manual labor should be developed. This need warrants sustained, comprehensive, and integrated genetic improvement, in which favorable alleles from cultivated and wild relatives are accumulated in superior cultivars. A three‐tiered breeding approach involving: (i) gene introgression from alien germplasm, (ii) pyramiding favorable alleles from different sources, and (iii) simultaneous improvement of multiple traits for common bean cultivars would be the most appropriate strategies to meet theses needs.

“…Wide crosses between different species of Phaseolus have been reported (Leonard et al 1987;Kuboyama et al 1991;Geerts et al 2002). Our results are consistent with the hypothesis explored by other authors, such as Adams et al (2000) and Marfil et al (2006) that the frequent gene alteration and phenotypic abnormalities observed in interspecific hybrids could be explained by the simple assumption that many loci in these plants become methylated.…”

Hybrid embryos resulting from crosses between Phaseolus species often fail to reach maturity and some combinations frequently abort at early developmental stages. The genetic or molecular basis for these consistent developmental defects is at present not clear. However, an extremely complex genetic system, thought to be caused by major epigenetic changes associated with gene expression changes, has been shown to be active in plant species. We have investigated DNA methylation in two interspecific hybrids, Phaseolus vulgaris 9 Phaseolus coccineus and its reciprocal crosses, using methylation sensitive amplification polymorphism (MSAP). The potential use of MSAP for detecting methylation variation during embryogenesis in interspecific hybrids is discussed. Significant differences in the DNA methylation patterns were observed in abortive (interspecific hybrids) and non abortive (parental) genotypes. Taken together, our results strongly suggest that generalized alterations in DNA methylation profiles could play a causative role in early interspecific embryo abortion in vivo. A considerable change in the methylation pattern during embryogenesis could be involved in the disruption of the regulation or maintenance of the embryogenesis process of Phaseolus interspecific hybrids. The results also support the earlier hypothesis that DNA methylation is critical for the regulation of plant embryogenesis and gene expression.
