MCQ
Genetically modified plants have been useful in increasing
  • A
    Crop yield
  • B
    Nutritional value of food
  • C
    Tolerance against abiotic stresses
  • All of the above

Answer

Correct option: D.
All of the above
d
(d)

Genetic modification of crops have resulted in

$(i)$ Increased tolerance against abiotic stresses (cold, drought, salt and heat)

$(ii)$ Reduced reliance on chemical pesticides (pest-resistant crops)

$(iii)$ Reduced post-harvest losses

$(iv)$ Enhanced nutritional value of food, $e . g .$, vitamin- $A$ enriched (golden rice)

$(v)$ Increased efficiency of minerals used by the plants (this prevents early exhaustion of fertility of soil)
