Book (stand-alone)Voluntary guidelines for the conservation and sustainable use of crop wild relatives and wild food plants 2017These Guidelines are aimed as reference material for national governments conservation and sustainable use preparing a National Plan for the Conservation and Sustainable Use of Crop Wild Relatives and Wild Food Plants. The focus is on in situ conservation and fostering linkages between it and the ex situ conservation and ultimately, the use of CWR and wild food plants. The precise process of preparing the National Plan will depend on the national context, including the availability of baseline data, existing policy framework, and remit of the agencies that are responsible for its formulation and implementation, as well as on the resources available for its implementation.

Book (stand-alone)Crop wild relatives of Kharga Oasis atlas
Sustainable management of Kharga Oasis agro-ecosystems project
2022Also available in:
No results found.Crop wild relative (CWR) is defined as a wild plant species that is more or less closely related to a particular crop and to which it may contribute genetic material, but that, unlike the crop species, has not been domesticated. CWR are considered enormous reservoirs of genetic variation, useful for plant-breeding initiatives and critical to meeting the challenge of global food security through enhanced agricultural production. They exhibit more genetic diversity than cultivated crops, as they have not been selected for domestication from a larger population, and can grow in a wide range of climates, soil and other physical features. In addition, wild species, climate and other environmental factors continue to adapt to their environment as they change. This document describes the different CWR in the Kharga Oasis and explains the importance of CWR in breeding programmes to improve the resistance of field crops to the different abiotic stresses such as drought and salinity. -
DocumentA Practical Approach on Creating a Restricted Ontology for Crop Wild Relatives
CWR ontology. Project report
2007Also available in:
No results found.The task to identify a subset of about 400 terms highly relevant to crop wild relatives was performed as a continuation to an earlier project where a set of about 11400 term was extracted from on-line sources. Terms with high relevance were grouped into themes, roughly corresponding to Agrovoc (top level) categories, or indicatives of the thematic sources from which the terms were collected (biological, geographical on-line dictionaries etc), with an attempt to balance the number of terms betw een the groups. For the import into the ontology structure the themes were converted to namespaces in order to preserve the grouping and allow manipulation within ontology client programs on terms based on namespace grouping. Before the import the namespaces were slightly modified and adapted to some other existing ontologies. In addition to selecting relevant terms and definitions, definition of vertical and horizontal relationships between the terms was performed. Terms were also linked to s ources (uris) through Dublin Core extensions of the ontology structure. The export from sql to rdf/owl was done with a script written in Perl that extracted the terms, descriptions, sources from the database, plus vertical hierarchy, term synonyms and other variants, as well as some simple horizontal relationships and produced an import file for Protégé in rdf/owl format. The resulting subset of terms was provided as a number of files; a main file containing core structure, object and da ta type definitions and term data in separate files per namespace, suitable for import by an ontology client program such as Protégé.
