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 ...
Advances in research conducted by the Centro Internacional de Agricultura Tropical together with its technicians in Central America, and the close collaboration with national programs are analyzed regarding factors limiting bean productivity in Central America: the bean pod weevil (Apion godmani)...

In 1976 expt. were conducted on var. trials, fertilization, insecticides, and herbicides in order to identify new technology that could be introduced into small- and intermediate-scale bean production in Honduras. Factors of a complete technological package were also discarded to identify the mos...

Anthropological work carried out by the PROFRIZA project in Cusco over 2 cropping seasons, between 1988-90, are reported. The status of bean cultivation in the region was assessed, as well as the experience acquired in seed production, small farmer management of farming activities, and the integr...
The effect of 2 daylength treatments (11 and 15 h) on stem elongation was determined in 5 indeterminate bean cv. (G 17650, G 2997, DOR 44, G 5475, and JU 80-11) under growth chamber conditions. Under the short day length, G 17650, a viny indeterminate var. showed the longest stem under all condit...

The method of selection used by CIATs climbing bean program is between the pedigree method (lineage) and the bulk population method. This method reduces the variation of each hybrid population in F, by individual selection. The evaluation of the germplasm bank was conducted in Popayan (1850 m abo...
