Which of the following is generally used for induced mutagenesis in crop plants?
Correct answer: C. Gamma rays (from cobalt-60)
- A. X-rays
- B. UV (260 nm)
- C. Gamma rays (from cobalt-60)
- D. Alpha particles
Explanation
Gamma rays are produced when an unstable atomic nucleus like cobalt-60 releases energy to gain stability. Sharbati Sonora and Pusa Lerma are the two important varieties of wheat that are responsible for the green revolution in India. These are produced by gamma rays treatment of Sonora-64 and Lerma Rojo-64 which are Mexican dwarf wheat varieties.
