Question 8
How has mutation breeding helped in improving the production of mung bean crop?
Answer
Mutation can be induced artificially through chemicals as well as through gamma radiations. The plants with desirable mutations can be selected and chosen as a source for breeding. This is called mutation breeding. This procedure has helped mung bean production by providing resistance against yellow mosaic virus and powdery mildew (fungal disease).
