Activities carried out by the Instituto Colombiano Agropecuario (ICA)-CIAT collaborative project on beans for cold climates in ICA`s regional center in Obonuco and in the dept. of Narino (Colombia) are reported. On the exptl. farm, 6233 materials were evaluated in bush bean trials, of which 103 were selected for good adaptation, high yields, and resistance to major diseases. Although there was a severe attack of halo blight (Pseudomonas phaseolicola) during the 1st semester of 1981, it was possible to obtain 108 bush bean materials resistant or tolerant to the disease. Best lines were ICA-Tundama, ANT 8, L 33341, L 33411, and L 33462 with commercial-colored grains (red and red/cream). These were also selected for regional trials during the 2nd semester against the check DIACOL-Andino. Best climbing bean lines identified were improved along with cv. Mortino to seek resistance to major diseases and higher productivity. In the evaluation of 393 new climbing bean collections, 41 belonging to the Ecuadorian and the Peruvian collections were considered promising. (Extract)
