The backcrossing method is the most appropriate to incorporate resistance to BCMV, anthracnose, and halo blight without affecting snap bean quality. When improvement is less specific and includes characteristics such as plant adaptation, yield, and stand, it is possible to use the reccurrent scre...

El metodo de retrocruzamiento es el mas apropiado para incorporar resistencia a BCMV, antracnosis y anublo de halo sin alterar la calidad de la habichuela. Cuando el mejoramiento es menos especifico e incluye caracteristicas como adaptacion, rendimiento y porte de la planta se puede utilizar el m...

Cassava is an important energy-rich food for millions of people in tropical developing countries. The crop has reached that status after thousands of years of evolution under diverse agro-ecosystems, movement of germplasm within and across continents, and more recently, through scientific genetic...

Assembled germplasm has provided breeders with valuable traits for the improvement of common beans. Molecular markers such as phaseolin and isozymes have facilitated understanding of the genus Phaseolus thus enabling breeders to develop more effective strategies. However, there are still gaps in ...

This paper describes two techniques used in Rwanda for integrating farmer expertise into bean varietal development. Standard farmer evaluation of on-farm trials can help: 1) indicate how varieties perform under farmer conditions; 2) better identify criteria critical to farmers; 3) target varietie...
