Solution
The correct option is C Mutation breeding The correct answer is mutation breeding:
Plant
breeding is the technique used to improve the variety of plants for human
welfare. Introduction, selection, hybridization and mutation breeding are the
main methods of crop improvement along with polyploid breeding, tissue culture
and genetic engineering. Introduction is the process of introducing new plants
from their old locality to the new one. Selection is the oldest method of plant
improvement in which suitable varieties are selected. It is of two
types-natural and artificial. Hybridization is the production of new varieties
by crossing two or more plants having different genetical constitution.
Mutation breeding is a quick way to introduce sudden changes in the genome of
the plant.
