Q. Virus free plants can be formed by

Strategies for Enhancement in Food Production

Solution:

Virus free plants can be formed by meristem cutlure. The reason behind this is that virus cannot propagate in rapidly dividing cells, so meristematic zones of plant always remain virus free.
For other options,
• Protoplast fusion technique is used for making somatic hybrids.
• Somatic cell culture technique is used to propagate plants from somatic cells using nutrient medium and combination of hormones.
• Callus culture is undifferentiated mass of tissue. Growing callus from plant organs is called callus culture.
