Conteúdo: |
An argument is made that a genetic resources policy for Manihot germplasm should follow a pragmatic line of action, i.e. to acknowledge that demand is determined by economics. The rationale is ideally embodied by constraints limiting the productivity of the cultigen cassava. Thus, collection should primarily be carried out to solve bottlenecks affecting existing breeding programmes. The breeders' needs are known but, since wild germplasm is virtually'no man's land', it becomes difficult for planners to make definitive recommendations as to what to collect. A tentative way out of this is to recommend collection on the basis of the models provided by the GP1, GP2 and GP3 genepools. Revision of the model should happen in the light of breakthroughs achieved in improvement programmes or at the berrder's request for trials with novel raw material described in the literature. |
