Tissue Culture

Meristem culture is the most effective technique to obtain virus-free plants from an infected parent because:

• The meristematic tissue (growing tip) is typically free of viruses due to:
• High metabolic activity.
• Absence of vascular connections to infected parts.
• When cultured in vitro, the meristem regenerates into a healthy, virus-free plant.

(A) Artificial hybridisation: Combines traits but does not eliminate viruses.

(C) Self-pollination: Passes on viral infections to offspring.

(D) Hydroponics: A soil-less growth method; no role in virus eradication.
