Breeding common bean (Phaseolus vulgaris L.) for yield in intercrop.
The present paper discusses some results from the literature on intercropping, addressed to answer the questions that are usually presented to breeders, with the following conclusions: 1. Germplasm developed for sole crop may be good for intercropping, but this is not always true; 2. The characteristics of bean plants that would be specifically adapted to intercropping are unknown, but disease resistance is important in all systems; 3. Due to some conflicting objectives, special breeding programs for intercropping may not be a good option generally; 4. A better approach might be a combined selection scheme, where early generation selection is made in sole crop, with testing of the best lines of each species as intercrops in all combinations of superior lines of the species, with cultivar reIease decisions being made on the basis of average yieIds of alI systems tested.
