Traditionally, plant breeders have made genetic changes in crops by using various crossing and selection methods, creating desirable hybrids; breeders also now attempt to induce favorable genetic mutations by the use of ultraviolet light, gamma radiation, or chemicals. With the development of genetic engineering, plant breeders have increasingly used its techniques to introduce desirable traits (i.e., genes), often from other species, into cultivated plants.
