It is possible to induce mutations artificially in plants through the use of chemical or radiations and then selecting and using those plants that have the desirable character as a source in breeding. This process is called mutation breeding. In mung bean, resistance to yellow mosaic virus and powdery mildew was induced by mutations.

Better management practices and increase in agricultural land area can increase yield of biomass but only to the limited extent. Plant breeding as a technology has helped in increasing the production to a very large extent.

Plant breeding is the purposeful manipulation of plant species in order to create desired plant typed which are better suited for cultivation and gives better yields; and are diseases resistant plant.
