Towards the end of 1977, the Bush Bean Architectural Improvement Project at CIAT was started with the following objectives: (1) to reduce yield differences between small- and large-seeded types; (2) increase yield capacity and (3) make the crop more attractive and competitive for the different pr...

Thirteen male sterile plants were identified in a yield trial of bean germplasm accession G08063 grown at CIAT-Palmira in 1977. Line G08063 is indeterminate, type III with postrate growth; it is relatively early and produces small white seeds. A fertility score (less than 1.3 sterile, 1.3-2.5 par...

A brief reference is made to new bean germplasm accessions and breeding lines identified at CIAT with specific architectural traits. Examples are given for type I bush beans with 10 or more nodes on the main stem, erect branching, suppressed branching, short foliage and internodes, lanceolate lea...

A selection study was conducted with 6 hybrid bean populations in 3 double groups, with low, intermediate, and high yield potential, at CIAT`s exptl. farm in Popayan (Cauca, Colombia), in a P-deficient soil with pH 4.5. These soil conditions allow for high disease incidence such as anthracnose (C...
