Question

Which of the following is not a trait that should be incorporated in a crop plant?

(a) Decreased tolerance to environmental stresses

(b) Increased yield

(c) Resistance to pathogens

(d) Increased tolerance to insect pests

This question was posed to me in quiz.

This key question is from Food Production Strategies topic in chapter Strategies for Enhancement in Food Production of Biology – Class 12

Answer 1

Right choice is (a) Decreased tolerance to environmental stresses

For explanation I would say: Traits or characters that the breeders have tried to incorporate into crop plants are increased crop yield, improved quality, increased tolerance to environmental stresses (salinity, extreme temperatures, drought), resistance to pathogens (viruses, fungi and bacteria) and increased tolerance to insect pests.
