Assertion : Wild varieties of crop plants must ne conserved.
Reason : Genome of wild plants serve as important resources for selection of desired genes like genes for pest resistance.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true bur reason is false.
D. if both assertion and reason are false.

Answer

A

Explanation

Plant breeding involves selection of parents with desired characters, their crossing and selection of hybrid progeny with desired character. Wild varieties of crop plants have better resistance to insects, pests, disease, etc. During plant breeding these wild varieties serve as germplasm resource where genes for disease resistance, etc., can be searched and selected. The wild varieties with desired character can be crossed with crop plants to obtain desired set of characters in the progeny. Therefore, wild varieties of crop plants must be conserved, otherwise a large germplasm store will be lost.
