Q. In , resistance to yellow mosaic virus and powdery mildew were induced by mutations.

NTA AbhyasNTA Abhyas 2022

Solution:

Mutation is the process by which genetic variations are created through changes in the base sequence within genes resulting in the creation of a new character or trait not found in the parental type. It is possible to induce mutations artificially by using chemicals or radiations (like gamma radiations) and selecting and using the plants with the desired character as a source in breeding – this process is called mutation breeding. In mung beans, resistance to yellow mosaic virus and powdery mildew were induced by mutations.
