Wide Hybridization in Crop Brassicas

A wide gene pool exists in wild species of most of the crop plants. In recent years, there has been a greater emphasis on the use of wild species in plant breeding, especially for transferring genes resistant to diseases and pests. Considerable number of examples in which desirable genes have been transferred from wild species to the cultivars are available (see Harlan 1984; Goodman et al. 1987).
