Step 1: Understanding the Concept:
Plant introduction is the process of introducing a plant species or genotype into an area where it has not been previously grown.
Many of India's leading commercial fruit cultivars are introductions from foreign research stations, wild collections, or commercial orchards.
Tracing the geographic origin and introduction history of these cultivars is a key aspect of systematic pomology.
Step 2: Detailed Explanation:
Let us analyze each pair individually:
(A) Banana-Grand Naine:
“Grand Naine” (or Grande Naine) is a prominent dessert banana cultivar belonging to the Cavendish group (AAA).
The name “Grande Naine” translates to “Large Dwarf” in French, and it was introduced to various international production hubs from France.
Thus, (A) matches with (II).
(B) Citrus-Kinnow:
The “Kinnow” mandarin is a high-yielding hybrid of 'King' (Citrus nobilis) \(\times\) 'Willow Leaf' (Citrus deliciosa) mandarins.
It was developed by Howard B. Frost at the University of California Citrus Experiment Station, USA, and released in 1935.
It was subsequently introduced to India and Pakistan, where it became a major commercial crop.
Thus, (B) matches with (III).
(C) Guava-Beaumont G-35:
This high-yielding, pink-fleshed guava cultivar, valued for processing and fresh consumption, was introduced from Australia.
Thus, (C) matches with (I).
(D) Mango-Carabao:
Also known as the Manila mango, “Carabao” is a famous, sweet mango cultivar originating from the Philippines, where it is a major export variety.
Thus, (D) matches with (IV).
Combining these matches gives: (A) - (II), (B) - (III), (C) - (I), (D) - (IV).
Step 3: Final Answer:
Hence, the correct matching is option (D).
