What are the various advantages of using genetically modified plants to increase the overall yield of the crop ?
Option A
Option B
Option C
Option D
Solution
Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms $(GMO)$. $GM$ plants have been useful in many ways. Genetic modification has:
$(i)$ made crops more tolerant to abiotic stresses (cold, drought, salt, heat).
$(ii)$ reduced reliance on chemical pesticides (pest-resistant crops).
$(iii)$ helped to reduce post harvest losses.
$(iv)$ increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).
$(v)$ enhanced nutritional value of food, e.g., Vitamin $‘A’$ enriched rice.
