Classical plant breeding methods

Enhanced Response of Plants to Previous Herbivory by Means of Classical Breeding Methods. Since plants within the same species may differ in their ability to produce and concentrate phytoalexins in response to stimuli, the idea is to identify such plants and use their regulating genes in classical breeding programs. 

Organic plant and animal breeding uses classical methods of crossing and selection based... 

It is important to be able to control plant diseases caused by bacteria, fungi, and viruses in an environmentally sound way,241 insofar as possible without the use of chemical pesticides. The classic method has been to breed resistant crops using genetic material from resistant wild relatives.
