Solution
The correct option is B Mutational breeding
The process of developing new variety by changing the genome through X-ray or UV radiation is known as mutation breeding. It is a quick method to obtain genetic variation. In this process, seeds are treated with a suitable mutagen which may be chemical or radiation (gamma radiation). After the treatment with mutagens seeds are grown in the field and self-pollinated. The obtained progeny will be grown in the next crop season. It results into a mutant line which is used as mutant variety.Thus, the correct answer is option B.
