The traditional empirical approach to selection for yield in common bean has met with modest success. Breeding based on the concepts of ideotype, or for specific combinations of physiological traits, and/or for combining ability based on specific genotypic combinations, have not been universally ...
Research and development of a reliable dry land production system for common bean (Phaseolus vulgarisL.) based on low-cost direct seeding and direct harvest methods was initiated at the Crop Development Centre at the University of Saskatchewan in the late 1980s. The target production area is a dr...
