Historical Context

The Act of Foundation of CIAT was signed on 17 October, 1967. The first research programs were established in 1969, including one on legumes. This program was almost nominal; it had no staff, except for a Coordinator who was a CIAT Director. Legumes were merely another research component of the Agronomic Systems Supporting Program that worked with bean, soybean, cowpea, and mung bean. In May 1972, CIAT’s Board of Trustees approved research on beans. In October of that year, the first bean team was organized and a world symposium on potential of field beans was held in Cali, Colombia, in February 1973, supporting the Board’s proposal. This meeting marked the beginning of CIAT’s Bean Program, as textually recorded in CIAT’s Annual Report 1973, page 5: "CIAT’s program in field beans was launched in February with an international seminar which explored the potentials of field beans and other food legumes in Latin America." The bean research team formally initiated its tasks in 1973 within the Bean Production Systems Program. In 1977, the approach changed, with the establishment of the Bean Program, to one of a multidisciplinary orientation that was retained until 1996. As of 1997, research was based on two broad projects: Project IP-1 (Bean Improvement for Sustainable Productivity, Input Use Efficiency, and Poverty Alleviation) and Project IP-2 (Meeting Demand for Beans in sub-Saharan Africa in Sustainable Ways).

The Bean Program was the first CIAT program to establish regional programs and also the first to turn its management over to national programs. The Regional Collaborative Bean Program for Central America, Mexico, and the Caribbean (PROFRIJOL) was launched in 1978 with the United Nations Development Program (UNDP) funding and, as of 1980, has been supported by the Swiss Development cooperation (SDC). The Regional Bean Program for the Andean Zone (PROFRIZA) operated between 1980 and 1999 under the auspices of the SDC. CIAT ceased coordinating PROFRIJOL in 1987 and PROFRIZA in 1998. PROFRIJOL will operate as a foundation as of year 2001, whereas PROFRIZA, as of year 2000, will operate through bilateral arrangements between the SDC and member countries. Regional programs for Africa were launched in 1983 with the creation of the Great Lakes Regional Program in Central Africa, financed by the SDC. In 1984, the Regional Program for Eastern Africa, financed by the Canadian International Development Agency (CIDA) and the United States Agency for International Development (USAID), was launched.

Distribution Channels

Finished materials: Advanced lines, varieties, gene bank accessions

Before 1976, the Bean Program occasionally distributed germplasm and sources of resistance to rust, and made shipments on behalf of the germplasm bank. The systematic distribution of germplasm began in 1976, after the CIAT’s Board of Trustees endorsed, in 1975, a proposal by the Technical advisory Committee (TAC) that the Bean Program coordinate the establishment of a Latin American research network. This network began operating in 1976, which was when the orderly distribution of finished materials began through the International Bean Yield and Adaptation Nursery (IBYAN). During the first 2 years, IBYAN distributed only varieties from national programs and promising materials from the germplasm bank. Advanced CIAT lines, which increasingly occupied a large part of the nursery, began being distributed as of 1978. In Central America and the Caribbean, as of the mid-1980s, the regional observation nurseries (VICAR and VICARIBE) and the yield trial nurseries (ECAR) began replacing IBYAN in the region as the largest supplier of finished materials. The same happened in Africa, as the regional AFBYAN nursery became an important source of distribution of improved germplasm for that continent.

As IBYAN declined as the main distribution channel of finished materials from CIAT headquarters, the Bean Team Nursery, better known by its Spanish acronym, VEF, gradually entered the scene. This observation nursery, which contained a large number of lines (>1500) of diverse origins (CIAT and national programs) of all market classes, was widely accepted. The VEF later changed its name to IBN (International Bean Nursery). The last IBN corresponded to 1996.

Early Generation Lines

In 1975, the first hybridizations were conducted at CIAT. By 1978, the generation of segregating populations and improved advanced lines was functioning adequately. CIAT therefore organized the work of the three bean breeders in a sequential scheme of germplasm evaluation and distribution (VEF-EP-IBYAN). The process worked as follows.

The advanced lines (hereinafter referred to as F4) were evaluated under the VEF-EP (at the national level)-IBYAN (at the international level) scheme. Early generations, in contrast, were handled through a regional division. Breeder I generated materials for Central America and the Mexican humid tropics; breeder II for the Andean Region, the Caribbean, and Africa; and breeder III, for Brazil, northwest Argentina, the semiarid areas of Mexico, and western Asia. Each breeder made the necessary contacts with breeders of the targeted regions to support them in developing bean populations according to specific requests and to provide them with sources of resistance to major production constraints. One golden rule followed was that no breeder would send early generation materials to countries outside his or her work areas to avoid overwhelming national programs with huge amounts of genetic material still being developed.

To benefit national programs with the materials produced by the three breeders, the Program established that all three should deliver their best F4s to be evaluated for one year in the VEF by the entire bean team (pathologist, entomologist, virologist, plant physiologist, and agronomist). Evaluations were conducted in both field and greenhouse. The best-performing VEF materials continued on to preliminary yield trials (EP), which, at the same time, served as a basis for selecting those lines that would enter the IBYAN. The three nurseries were at the disposal of the national programs that, accordingly, received the best advanced materials of the three CIAT bean breeders. As of 1994, the breeders’ geographical responsibility gave way to task division based on the genetic diversity of beans: one breeder was in charge of beans of Mesoamerican origin and another of beans of Andean origin. The VEF(IBN)-EP-IBYAN scheme ceased operating in 1996.
