La Colorada, on the North Coast of Colombia, was chosen by CIAT to study new technology validation in cassava. Trials measured the productivity of improved cassava production technology under actual field conditions, defined factors limiting cassava yields that may have been overlooked in the des...

Research on lima beans (Phaseolus lunatus) was conducted regarding adaptation, resistance to common bacterial blight (Xanthomonas phaseoli), resistance to leafhoppers (Empoasca kraemeri), and cyanide concn. in lima bean seed. In adaptation studies 36 climbing lima bean lines were selected from th...

Some basic definitions on genetics in relation to bean cultivation are presented in which a description is given on how to use this information in a breeding program. Examples are given on the management of quantitative characters (yield and plant height) controlled by different genes and qualita...

Based on the considerations related to the characteristics of cassava, centers of origin, and the traditional system of cultivation, several conclusions were made regarding the relationships between the plant and NPFs, constituted by disease and pest pressures and edaphic and climatic factors. It...

The Central American Adaptation Nursery (VIDAC 1988), comprising the best black- and red-seeded lines evaluated in the 1987 VIDAC, was established to identify well-adapted bean genotypes and obtain information on their degree of resistance to different crop problems. Outstanding (1) black-seeded ...
