However, now, in addition, techniques are available to augment this variation by the introduction of ‘foreign’ genes.

Marco Kesting,Rainer Lutz,Manuel Weber., 1988) have been introduced into crop plants via gene transfer techniques. Unfortunately much of this progress has not benefited cereals, as general techniques for transferring genes into cereal plants, such as rice (.), wheat (.) and maize (.), are not as advanced as for many of the dicot plants.
