Vedclass · Answer

(A) In case of vegetatively propagated crops,pure-line selection is not required because these plants are clones and genetically identical.Pure-line selection is a method used primarily for self-pollinating,sexually reproducing plants to isolate homozygous lines.Hybrid vigour (heterosis) is indeed most profitably used in vegetatively propagated crops because the hybrid traits can be maintained indefinitely through vegetative propagation without the risk of segregation or loss of superiority that occurs in sexual reproduction.Therefore,both the Assertion and the Reason are correct,and the Reason provides a valid explanation for why pure-line selection is unnecessary in these crops.

Assertion : In case of vegetatively propagated crops,pure-line selection is not required.
Reason : Hybrid vigour is mostly used in vegetatively propagated plants.
