Disease resistance in plants is an attribute which ensures the survival of the species against the agents of disease. It is evolved in nature in the course of natural selection and is genetically controlled. Extensive use of this property is made in breeding resistance into susceptible but otherwise desirable varieties. The nature of resistance, however, is but little understood; although, on the basis of numerous morphological, anatomical, chemical and physiological studies, several theories of resistance have been offered.
