With reference to agriculture in India, how can the technique of ‘genome sequencing', often seen in the news, be used in the immediate future?

  1. 1.Genome sequencing can be used to identify genetic markers for disease resistance and drought tolerance in various crop plants.
  2. 2.This technique helps in reducing the time required to develop new varieties of crop plants.
  3. 3.It can be used to decipher the host-pathogen relationships in crops.

Select the correct answer using the code given below:

  1. A.1 only
  2. B.2 and 3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: D. 1, 2 and 3

Genome sequencing allows scientists to identify specific genes associated with desirable traits such as disease resistance or tolerance to environmental stresses like drought. This knowledge accelerates plant breeding by enabling marker-assisted selection, significantly shortening the development cycle for new crop varieties. Furthermore, understanding the genetic makeup of both crops and pathogens is crucial for deciphering their interactions, leading to improved disease management strategies.
