Crop wild relative common ancestor, particularly in the Brassica family and plants. Many vegetables are also hybrids of different species, again this is particularly true of Brassicas. Crop wild relative A crop wild relative (CWR) is a wild plant closely related to a domesticated plant, whose geographic origins can be traced to regions known as Vavilov Centers (named for the pioneering botanist Nikolai Vavilov). It may be a wild ancestor of the domesticated plant, or another closely related taxon. The wild relatives of crop plants constitute an increasingly important resource for improving agricultural production and for maintaining sustainable agro-ecosystems. With the advent of
