    Notizen: [Auszug] SIR-In recent months, controversy has arisen internationally over the conservation and availability of plant genetic resources, the genetic diversity of primitive varieties of crop plants and related wild species upon which future crop improvement programmes will depend. Much of the controversy ...

    Notizen: Abstract The signing and ratification of the Convention on Biological Diversity has resulted in increased scientific and public interest in the conservation and utilisation of biological diversity. This has in turn triggered the need to develop more effective methodologies to conserve biological diversity for the benefit of all humanity. One of the first factors to be considered when conserving botanical diversity is the efficient and effective selection of the target taxa. The aim of this paper is not to set detailed priorities for the genetic conservation of the plant genetic resources of any particular crop or species complex, but to draw attention to the factors that should be considered when formulating priorities. The factors that are considered important when selecting plant genetic resource targets are: current conservation status; potential economic use; threat of genetic erosion; genetic distinctiveness; ecogeographic distribution; biological importance; cultural importance; cost, feasibility and sustainability; legislation; ethical and aesthetic considerations; and priorities of the conservation agency undertaking the conservation. Each of these factors is discussed in turn. Although it is not possible to provide a single methodology for the selection of plant genetic resource targets at this time, it is hoped that the consideration the factors discussed will make the selection of target taxa more object, make better use of the limited conservation resources and thus enhance the process of genetic conservation as a whole.

    Notizen: Abstract Vavilov's ideas on New World centres of crop plant diversity are reviewed and the development of his ideas from 1926 to 1940 are described. More recent collecting work and taxonomic studies by the author confirm largely the delimitation of the American gene centres suggested by Vavilov, even in regard to details, e.g. within Bolivia.

    Notizen: Abstract A database has been developed for the collections of wild and cultivated potatoes examined by the author in the world herbaria and in his own collections. A total of some 9,000 collections were examined, amounting to approximately 27,000 herbarium sheets when duplicates in different herbaria were taken into account. The information is arranged in twenty-one fields and the system used is DBase IV, version 1.1. 15.00 (including postage and packing) by applying to the author at the above address. Sterling cheques should be made payable to J.G. Hawkes.
