Breeding cassava relies on a phenotypic recurrent selection that takes advantage of the vegetative propagation of this crop. Successive stages of selection (single row trial- SRT; preliminary yield trial – PYT; advanced yield trial – AYT; and uniform yield trials UYT), gradually reduce the number...

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. ...

Genetic variance, heritability, and expected response from selection are useful in devising alternative methods and criteria of selection. The objectives of this study were to estimate these for seed yield and its components from 200 F2 populations involving 80 cultivars and lines of mostly small...

Weed control in Latin America is costly and heavily dependent upon herbicides. Often irrigated rice farmers spray herbicides in late post-emergence at 30 to 44 days after emergence (d.a.e.). The economic benefits from such late applications are often unclear. Two experimental approaches involving...
