- There has been a concerted world effort to explore, collect and conserve the genetic diversity of our crops and their wild relatives. To attain these objectives carefully planned expeditions are needed. The collecting team, the route and the timing of an expedition are discussed here. In particular, the collecting strategy, based on population sampling, the nature of the material, whether seeds (orthodox or recalcitrant) or vegetative material, and methods of storage during the expedition, arc of exceptional importance. Documentation of samples is also of particular importance as part of the overall strategy in germplasm exploration.
