Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Quince C is one of the most famous dwarfing rootstocks for pear.
If you identify that (C) matches with (III), you can easily narrow down the options in competitive match-the-following questions.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Rootstocks are used in fruit production to control tree size, induce early bearing, and provide resistance to soil-borne pathogens or adverse climatic conditions.
For Pear (Pyrus communis), Quince (Cydonia oblonga) rootstocks are widely used to control vigor.

Step 2: Detailed Explanation:
Let us match each rootstock from List-I with its characteristics in List-II:
- (A) Quince A: This is a widely used clonal rootstock for pear.
In standard horticultural classification, it behaves as a vigorous rootstock compared to other dwarfing Quince selections (though it is semi-dwarfing compared to wild seedling pear rootstocks).
Thus, (A) matches with (I).
- (B) Quince B: This selection induces a semi-vigorous growth habit in grafted scions, making (B) match with (II).
- (C) Quince C: This is a classic, highly dwarfing rootstock.
It is used for high-density plantings because it reduces scion vigor significantly and promotes early, prolific bearing.
Thus, (C) matches with (III).
- (D) Pyrus pashia (Kainth): This is a wild pear species native to the Himalayan region.
It is highly cold-tolerant, has a deep root system, and is suitable for hilly regions where soils can be shallow and gravelly.
Thus, (D) matches with (IV).
This matching aligns with the sequence: (A) - (I), (B) - (II), (C) - (III), (D) - (IV).

Step 3: Final Answer:
The correct matching sequence is (A) - (I), (B) - (II), (C) - (III), (D) - (IV).
