Abstract
During 1985 work in bean pathology at CIAT was concentrated on angular leaf spot, root rot pathogens, and halo blight. The main activities regarding these 3 diseases was the identification of new and better sources of disease resistance. Work was also carried out with rust, Ascochyta, web blight, and common bacterial blight diseases. As in previous years,…

Abstract
Evaluations of host-plant resistance to Empoasca kraemeri, bruchids, and Apion godmani continued in 1985. Leafhopper-resistant breeding lines from 5 cycles were evaluated in the field to determine whether advances in overall resistance levels had been obtained over cycles of selection. The identification of wild Phaseolus vulgaris germplasm from Mexico with…

Abstract
The main emphasis of the BCMV research at CIAT-Palmira was the characterization of black root resistance mechanisms and identification of new resistance sources. Concerning BYMV, the main research effort in 1985 was the characterization of the new BYMV-0I (Orfeo-INIA) strain, which occurs in Chile. This new strain has been isolated to look for new sources of…

Abstract
Economics research at CIAT in 1985 focused on production studies, marketing studies, and training. Production studies identified farm level constraints, evaluated new technologies as solutions to these constraints, and assessed the adoption of new technologies. Since most beans in Latin America reach the consumer through the market, consumer preferences,…
