Which of the following are the features of genetically modified crops?

All of these.

a- More tolerance to abiotic stress.

b- Reduction in post harvest losses.

c- Enhanced nutritional value of food.

d- All of these is the correct option .

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., golden rice, i.e., Vitamin ‘A’ enriched rice.
