Assertion: In case of vegetatively propagated crops, pure-line selection is not required.
Reason: Hybrid vigour is mostly used in vegetatively propagated plants.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
Explanation:
In case of vegetatively propagated crops, pure line selection is not required. Pureline selection is useful only for sexually reproducing plants. Hybrid vigour is most profitably used in vegetatively propagated crops because they do not involve sexual reproduction and hence no loss of hybrid superiority.
