Description The author traces the development of "Polygon Breeding", which originated in E. Africa under the name "Diversified Bulk Population Breeding" in the cultivation of Phaseolus vulgaris, describing it as a multilocational breeding method with complete and continued sharing of populations and selections. Diagrams illustrate its application in triangle, tetragon and pentagon modes. A description is provided of a tetragon programme conducted for 4 chickpea cross populations in 1985-90, which showed that selection in one of 4 chosen environments was consistently more effective than in the other environments. The author concludes that the method is advantageous in (1) offering less restriction than breeding in one location, (2) enhancing national and international collaboration, (3) leaving options for wide-to-narrow adaptation, and (4) possibly helping avoid rivalry among breeding programmes.
