Question

Which of these statements define the characteristic of Bt. cotton?

• A. High yield and resistance to bollworms.
• B. Long fibre and resistance to aphids.
• C. Medium yield, long fibre and resistance to beetle pests.
• D. High yield and production of toxic protein crystals, which kill dipteran pests.

Answer 1

Answer: (A)

High yield and resistance to bollworms.

Bt cotton is a genetically modified variety of cotton producing an insecticide. The main purpose is the reductions in pesticides to be sprayed on a crop and the ecological benefits, which stems from that. It is used in response to an outbreak of cotton bollworm, Helicoverpa armigera.

So, the correct answer is 'High yield and resistance to bollworms.'
