Metodologia de la investigacion aplicada a la asociacion frijol- maiz

Autor: Davis, J.H.C.

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...

Conceptos basicos de genetica de frijol

Autor: Davis, J.H.C.

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...

Orientacion del mejoramiento de frijoles volubles

Autor: Davis, J.H.C.

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...

The effect of photoperiod and temperature on yield in beans

Autor: Davis, J.H.C. Gniffke, P

Photoperiod insensitivity in the germplasm collection of beans (Phaseolus vulgaris) held at CIAT is found mostly in accessions from higher latitudes. Cold tolerance is found in accessions from the high Andes, but these are all photoperiod sensitive. A break in adaptation seems to occur at about 1...
