Genetic manipulation is a process of transferring (genes) characters that are desirable from one plant to another plant. In simple words it can be seen as changing the normal gene arrangement according to your desirable needs.
When the gene for a particular character is introduced in a plant cell, a transgenic plant is produced. These transgenic plants have characters of both the old and the newly introduced genes or just the new gene.
For example, let us assume there is a wild plant that produces small fruits. If a gene responsible for a larger fruit size is introduced in this plant, this plant becomes transgenic, and starts producing larger fruits. Similarly, genes for higher yield, disease resistance, etc. can be introduced in any desired plant. Therefore, gene manipulation plays an important role in agricultural practices. It helps in improving crop variety. It ensures food security and insect resistant crops. It also improves the quality and yield of crops.
