Genetic improvement includes selection, testing and breeding from the species dowwn to the clonal level. Tree-breeding programmes in tropical countries are often required to work with many provenances of many species for many sites. A Multuple Population Breeding Stratiegy (MPBS) was propsed in response to this need and the breeding seediling orrchard (BSO) devised to combine the conventional hierarchy of sequential testing, selection and seed production populations in a single planting.
