Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Crop improvement by mutation breeding is based on induced mutations.
Reason (R): Mutation creates genetic variations through changes in the base sequence within genes resulting in the creation of a new character or trait not found in the parental type.
 In the light of the above statements, choose the most appropriate answer from the options given below :
1. Both (A) and (R) are true but (R) does not explain (A).
2. Both (A) and (R) are true and (R) is the correct explanation of (A).
3. Both (A) and (R) are false.
4. (A) is true but (R) is false.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Breeding and development of cultivars resistant to disease enhance food production in areas where the disease is prevalent.
Reason (R): Resistance to a disease is determined by the genetic constitution of the host plant.
 In the light of the above statements, choose the most appropriate answer from the options given below :
1. Both (A) and (R) are false.
2. Both (A) and (R) are true but (R) does not explain (A).

Identify the correct statement:
I: New cultivars produced by plant breeding are first evaluated in research fields and their performance is recorded under ideal fertiliser application, irrigation, and other crop management practices.
II: After evaluation in research fields, the new cultivars are tested in farmers’ fields for at least three growing seasons at several locations in the country.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Cross hybridising the two parents to produce hybrids that genetically combine the desired characters present in the parents is a tedious and time-consuming process.
Reason (R): The desired characters have very often to be combined from two different plants [parents].
 In the light of the above statements, choose the most appropriate answer from the options given below :
1. Both (A) and Reason are true but (R) does not explain (A).
2. Both (A) and (R) are true and (R) is the correct explanation of (A).
