Three trials were carried out at CIAT-Palmira to quantify the effect of plot edges and useful plot size in beans. In the 1st trial (sown in Oct. 1977), the competition effect of 36 climbing bean var. associated with maize ICA H-210 in adjacent plots and the effect of the alleys on plot edges were...

Metodologia de la investigacion aplicada a la asociacion frijol- maiz
The results are presented of 3 expt conducted at CIAT to improve var. destined for use in multiple-cropping systems; (1) evaluation of bean var. (bush and climbing) in 2 cropping systems, monoculture and in association with maize; (2) evaluation of 20 maize genotypes in monoculture and in associa...

Interacciones de genotipos por sistema de cultivo en frijol y maiz
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...
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...
Bean germplasm was evaluated at CIAT for resistance to BCMV strains NL-4, NL-3, and NL-5 in order to use them in the national breeding and selection programs in Africa, Europe, USA, and Chile. Ninety-eight lines were selected for an international Bean Common Mosaic/Black Root resistance nursery. ...
Five bean cv. were exposed to natural daylength (approx. 12 h) and ambient temp., or to 6 h daylength, achieved by moving pots into a darkened room to determine their response to photoperiod. Cv. Mortino and Frijolica 0- 3.2 did not flower under the control conditions, but with the short day trea...
