Knowra Crop wild relatives Crop wild relatives Crop wild relatives are wild plant species related to domesticated crops. They can carry inherited traits useful for crop improvement, including resistance to pests, diseases, and environmental stress.
Crop breeding : The deliberate crossing and selection of plants to develop crops with desired traits. Breeders cross crops with wild relatives to introduce useful inherited traits.
Genetic diversity : The variation in genetic information among individuals, populations, or species. Wild relatives often retain variation absent from modern crop varieties.
Teosinte : A group of wild grasses in the genus Zea, including the wild ancestors of maize. Teosinte is the wild relative from which domesticated maize was developed.
In situ conservation : The conservation of species and genetic diversity within their natural habitats. Protected habitats allow crop wild relatives to evolve and persist in the wild.
Climate change and biodiversity : The effects of climate shifts on species, ecosystems, and biological diversity. Changing climates may shift wild-relative ranges and alter which populations remain available.
Introgression : The transfer of genetic material from one population or species into another through hybridization and repeated backcrossing. Backcrossing can move a wild relative’s useful gene into a crop while retaining crop characteristics.
Gene bank : A facility that preserves genetic material from plants, animals, or microorganisms for future use. Gene banks conserve seeds and other material from wild relatives for research and breeding.
Crop wild relatives of wheat : Wild grasses related to wheat, including species in the genera Aegilops and Triticum. Wild wheat relatives have provided resistance traits and genetic diversity for wheat improvement.
Ex situ conservation : The conservation of biodiversity outside its natural habitat, such as in seed banks or botanical collections. Stored samples safeguard wild-relative diversity when habitats are threatened or populations decline.
Taxonomy : The science of naming, defining, and classifying organisms. Disputed species boundaries can affect which plants count as crop wild relatives.
