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.
