Abstract
On-farm research activities in 1986 continued in the areas of training, network establishment, methodology adaptation, technology development on-farm, and technology adaptation to specific areas. One early result is a better understanding of the variability in the adaptation of the newly adopted var. Gloriabamba in different parts of…

Abstract
The Great Lakes Regional Bean Program works with the agricultural research institutions of Burundi, Rwanda, and Zaire. Advanced breeding lines were introduced as potential new var. for the region and/or as sources of resistance to angular leaf spot, anthracnose, Ascochyta leaf spot, halo and BCMV, and the bean fly. Together with…

Abstract
Close collaboration between CIAT and Brazil continued during 1986. Germplasm development was conducted through evaluating the jointly developed crosses in Brazil, rather than selecting the fixed lines in CIAT prior to shipment to Brazil. By the end of 1986, those segregating populations were in the F4-F5 generations ready for adaptation…

Abstract
Evaluation of photoperiod bean response in flowering screening continued at CIAT-Palmira, using artificial 18 h daylengths to delay flowering. Approx. 600 germplasm accessions were evaluated in 1986 as a part of continuing efforts to characterize responses of germplasm in different bean…

Abstract
During 1986 the emphasis on the acquisition of Phaseolus germplasm continued to be directed to land races and wild species. In addition to intensive expeditionary work in Latin America, several interesting materials from Europe, Asia, and Africa were received. Of the last batch of 6000 new accessions approved by the Instituto Colombiano…

Abstract
During early 1986 computer programs were written to manage the expt. part of the bean database. In mid-year the programs were redesigned and recompiled to better access the data. In all, some 53 new dialogs were written to facilitate consultation of the bean database. All of the bean evaluation nursery and IBYAN data will be loaded together with passport and other data…

Abstract
During 1986 screening of advanced bean lines for efficiency at low levels of P and for tolerance to high levels of Al saturation continued. A review of data from 8 yr. of screening indicated that the genetic variability of beans for these 2 characteristics is low. Furthermore, the data suggest that efficiency and…
