HYBRIDIZATION and introgression are natural biological processes that can occur among closely related species. For instance, it has long been recognized that cultivated plants naturally hybridize with their wild relatives (de Candolle, 1882). The major crops of wheat, rice (Oryza sativa L.), maize (Zea mays L.), soybean [Glycine max (L.) Merr.], cotton (Gossypium hirsutum L.), sorghum [Sorghum bicolor (L.) Moench], bean (Phaseolus vulgaris L.), sunflower (Helianthus annuus L.), and sugarcane (Saccharum officinarum L.) all have wild relatives to which they can cross (Ellstrand et al., 1999). Wild or weedy relatives may be able to acquire genes from commercial cultivars when ...
