Question
What are the various advantages of using genetically modified plants to increase the overall yield of the crop?
✓
Answer
GM plants have been useful in many ways. Genetic modification has:
- Made crops more tolerant to abiotic stresses (cold, drought, salt, heat).
- Reduced reliance on chemical pesticides (pest-resistant crops).
- Helped to reduce post-harvest losses.
- Increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).
- Enhanced nutritional value of food>e.g., Vitamin ‘A’ enriched rice.
