Report 1981

Autor: Davis, J.

The process of selection in climbing bean improvement should be conducted with maize in association due to the high cost of sole cropping with stakes or with a trellis system. The relation between yields of beans and maize is negative and the regression coefficient is normally between -1 and -2. ...

Report 1980

Autor: Davis, J. García, S. Tejada, G

Studies were conducted at CIAT to test a new methodology (1) to improve F3, yields through the use of a hierarchical exptl design (a 9 x 9 lattice with 3 replications, with lines grouped according to the design, without taking into accont the family of origin) and (2) to select beans in associati...

Maize and climbing beans as associated crops prevail in the highlands of L.A. in traditional systems with low populations and manual planting (in rows and pocket drilling). Two trials were establislied to compare the systems, testing bean densities from 4- 12 plants/m(2) and 3-12 plants/m(2), wit...

Some methodologies, including examples, for developing bean var. specifically adapted to intercropping with maize are considered. Since every breeding program has to contend with genotype x environment interactions, decisions have to be made regarding the locations for breeding nurseries, the con...

The methodology used and the results obtained are discussed for an investigation conducted at CIAT on agronomic factors of maize- bean associations: planting method, density and date, stakes used, fertilization and cultural practices. It was concluded that if high technological levels are used, t...
