Genetic manipulation is a process in which genes of desirable characters are taken from one plant and transferred to another plant using the technique of hybridization. This process helps in improving the crop variety, ensuring food security, and producing insect-resistant crops. For example, if there is a wild plant that produces small fruits, the gene responsible for larger fruit size can be introduced into this plant, making it transgenic and producing larger fruits. Similarly, genes for higher yield, disease resistance, etc. can be introduced into any desirable plant. Therefore, genetic manipulation plays an important role in agricultural practices.
