A summary is presented of results of trials conducted as part of the collaborative agreement between the Instituto Colombiano Agropecuario and CIAT on bean research during 1981 in La Selva, Antioquia (Colombia). During germplasm evaluation, 112 promising materials were identified for their adapta...

The concept of plant genetic variability is studied as well as how it should be treated and presented to the researcher, especially in the management of bean genetic resources. Given the spread of some crops such as soybeans and pods, searching for variability in the available genetic resources f...

CIAT is currently the world center for all the germplasm of the genus Phaseolus. The bean program has the main objective of increasing bean production and productivity. Germplasm improvement involves a program of evaluation and identification of genetic diversity, improvement through more effecti...

Common beans (Phaseolus vulgaris L.) are an important world crop with a relatively low productivity in most cropping systems. Physiological factors influencing yield are discussed in this paper with respect to field research in the tropics. The comparative earliness of the majority of the germpla...


Laing, DRKretchmer, PJZuluaga G, S[Physiological studies on yield and adaptation in Phaseolus vulgaris L]Physiological studies on yield and adaptation in Phaseolus vulgaris L

A report is given on the 4 cultivated species of the genus Phaseolus, studying geographic distribution, taxonomy and morphology, agronomic characteristics and germplasm collection. The areas where Phaseolus vulgaris is extensively cultivated are North, Central and South America, Europe and E. Afr...

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...
