The above considerations make it difficult to identify populations that are at risk. Loss of Diversity within Populations The above concepts relate to the reduction in survival of germplasm in nature, or, at the extreme, total extinction. However, populations that are apparently thriving may still be losing diversity for certain loci (Ryan 1992, p. 32). Since agricultural genebanks exist primarily for the economic enhancement of the crop, it is appropriate to consider the risk with respect to loci of economic importance.
Comparison of ex situ and in situ Populations Another important concern in the conservation of potato genetic resources is whether samples in the genebank, although genetically stable (del Rio et al. 1997a), still are representative of the populations taken from the wild during explorations, sometimes many decades ago. This has consequences with respect to the value of ex situ collections as "back-ups" and the worth of re-collecting "new" samples at the exact original sites. Population dynamics in the wild are very complex.
Did the genebanks generate artificial differentiation by reducing (genetic bottleneck) or increasing (promoting allelic recombination) the genetic diversity? Is new diversity evolving in the wild or are these populations suffering genetic erosion? Genebank samples were shown to be quite stable (del Rio et a1 1997a), but could they undergo a significant genetic change when they are first incorporated into the genebank? For one thing, the materials in question were collected as tubers and conversion to sexual seeds by artificial means at the genebank might have imposed selection.
