(A) Intercontinental plant introduction
(B) Intercontinental plant introduction
(C) Both A and B
(D) None of the above

Answer 1

Hint: For the improvement of crops various methods are introduced that include the introduction of the genotype of the plant from where it grew to the new places.

Complete answer:To solve this question, we have to understand about the crop improvement methods.
The crop improvement methods are of different types; intercontinental plant introduction, interstate plant introduction, intrastate or intra-district plant introduction, and intracontinental plant introduction.
In intercontinental plant introduction, the plant that grows in any country is introduced to another continent like, introduction of the Ridley white variety from Australia to India. In interstate plant introduction, the plant that grows from one state is introduced within the same country, like N.P. wheat varieties from Delhi. In the intrastate or intra-district plant introduction, the plant grown in different states or from different districts is introduced within the same state of district, and in the intra-continental plant introduction, the plants grown in a country are introduced to the area of the same continent.

Now lets us find the solution from the given options:
Intercontinental plant introduction means the introduction of plants that grow in a country to another continent. The introduction of wheat variety from Australia to India is an example of intercontinental plant introduction.
Next, intra-continental plant introduction means the introduction of plants that grow in a country to another country of the same continent.

Hence, the correct option is (A). Intercontinental plant introduction.

Note: There are many other methods that involve the crop development techniques. After the introduction of plant materials it is used for hybridization or for selection with indigenous germplasm to produce the desired improved plant that is suitable for cultivation.
