Question

Which one of the following statements is wrong in relation to transgenic Bt cotton plant?

• A. Crop yield loss due to attack by Bacillus thuringiensis bacterium is reduced
• B. Crop yield loss due to attack by lepidopteran insect pests is reduced
• C. The use of chemical insecticides in the cotton field is minimized
• D. Better quality cotton is produced

Answer 1

The correct option is D Better quality cotton is produced

In Bt cotton plant, a toxin gene from Bacillus thuringiensis is inserted to obtain resistance to pests. This resistant gene reduces the crop yield loss due to attack by Lepidopteran insect pests. The use of Bt cotton minimizes the use of chemical insecticides in the cotton field. The quality of the Bt cotton thus obtained is better.

Thus, the correct answer is option D.
