Question 6: (a) Mutations are beneficial for plant breeding. Taking an example, justify the statement.
(b) Discuss briefly the technology that made us self-sufficient in food production.
Answer:
- 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.
- Traditional farming can only yield a limited biomass which is used as food for humans and animals. 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. This technology has given support to green revolution which was responsible for not merely meeting the national requirements in food production but it also helped us in the exportation.
