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.
