Question

Which of the following is generally used for
induced mutagenesis in crop plants ?
(a) X-rays
(b) UV (260 nm)
(c) Gamma rays (from cobalt 60)
(d) Alpha particles

Answer 1

Answer:

Gamma rays (from cobalt 60) is generally used for induced mutation in crops plants.

Answer 2

(c) Gamma rays (from cobalt 60) are generally used for induced mutagenesis in crops.

Explanation:

Subjecting plants to physical and chemical agents in order to alter their DNA and introduce traits that can be passed on to the offsprings is commonly referred to as induced mutagenesis.

Crops are commonly subjected to physical agents like ionizing radiations to alter their DNA. Gamma rays have become a commonly used type of radiation in this process.

Mutagenesis in plants is carried out to increase yield, enhance disease resistance, etc.
