“…The mass‐pedigree (Beebe et al, 1993; Grafton et al, 1993; Singh et al, 1989, 1993), pedigree (Kelly et al, 1994a, 1994b), and recurrent backcross (Alberini et al, 1983; Bliss, 1993; Miranda et al, 1979; Pompeu, 1980, 1982) methods and their modifications often were used for common bean improvement. Researchers also have used congruity backcrossing (Haghighi and Ascher, 1988; Mejía‐Jiménez et al, 1994; Urrea and Singh, 1995), single seed descent (SSD) (Kelly et al, 1989; Urrea and Singh, 1994), recurrent (Beaver and Kelly, 1994; Duarte, 1966; Kelly and Adams, 1987; Singh et al, 1999; Sullivan and Bliss, 1983), and gamete selection (Singh et al, 1998a) methods.…”

“…The taller Type II cultivars also are required for large scale mechanized commercial farming to reduce disease incidence, dependence on hand labor, and production costs (Vandenberg and Nleya, 1999). The I gene for BCMV resistance, gene(s) for anthracnose resistance, and/or Type II growth habit were transferred from cultivars of different market classes within Mesoamerica race in the Central American small reds (Beebe and Pastor‐Corrales, 1991; Beebe et al, 1993) and Brazilian carioca (cream striped), jalinho (beige), and mulatinho (cream) beans that were characterized by prostrate growth habit Type III (Alberini et al, 1983; Miranda et al, 1979; Pompeu, 1980, 1982; Singh et al, 1998a; Thung et al, 1993).…”

“…Resistance to BCMV, BGMV, CBB, leafhopper, bruchid, and bean pod weevil, and upright plant type in red and black beans in Central America were improved (Beebe and Pastor‐Corrales, 1991; Beebe et al, 1993; Kornegay and Cardona, 1990, 1991). Most of these traits, with the exception of bean pod weevil resistance (which was not required), and resistance to angular leaf spot, anthracnose, and drought stress were bred into cream, cream striped, and beige types for Brazil (Alberini et al, 1983; Miranda et al, 1979; Pompeu, 1980, 1982; Singh et al, 1992c, 1998a; Thung et al, 1993). Additional information regarding genetic improvement of Mesoamerica race cultivars can be found in a recent article by Singh (1999b)…”

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.
