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:
  1. Made crops more tolerant to abiotic stresses (cold, drought, salt, heat).
  2. Reduced reliance on chemical pesticides (pest-resistant crops).
  3. Helped to reduce post-harvest losses.
  4. Increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).
  5. Enhanced nutritional value of food>e.g., Vitamin ‘A’ enriched rice.
In addition to these uses, GM has been used to create tailor-made plants to supply alternative resources to industries, in the form of starches, fuels and pharmaceuticals.
