Researchers from Spain have identified the crop wild relatives (CWR) that
could be used as gene sources to develop new varieties that are adapted to
The study, published in Genetic Resources and Crop Evolution, has a list of
929 wild plants related to 203 crops of interest in the country, with the
aim of identifying "the genes needed by the Spanish agriculture". The study
presents a prioritized checklist of CWR in Spain in which the criteria of
crossability with crops of economic importance, endemicity, and threat
status have been taken into account.
The crops were classified into use categories: food (24%), forage and fodder
(32%), ornamental (28%), and industrial and other uses (16%), depending on
their main use.
