Question

Match List I with List II
List I (Variety):
A. Varsha Uphar
B. Pusa Sawani
C. Prabhani Kranti
D. Punjab-8

List II (Pedigree/Parent):
I. Lam selection-1 x Parvani Kranti
II. Mutant from Pusa Sawani
III. Pusa Sawani x A. manihot
IV. Pusa Makhmali x IC1542

Choose the correct answer from the options given below:

• A. A - I, B - IV, C - III, D - II
• B. A - IV, B - II, C - I, D - III
• C. A - III, B - I, C - II, D - IV
• D. A - II, B - III, C - IV, D - I

Hint:

Key okra parents to remember:
Prabhani Kranti $\rightarrow$ Developed using the wild species A. manihot to introduce YVMV resistance.
Pusa Sawani $\rightarrow$ Cross of Pusa Makhmali and IC1542.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Pedigree and parental selection are key aspects of plant breeding programs.
Matching developed varieties with their specific parents helps trace the source of desirable traits, such as disease resistance.

Step 2: Detailed Explanation:
Let us match the okra (Abelmoschus esculentus) varieties in List I with their corresponding pedigree in List II:
1. Varsha Uphar (A): This variety was developed from the cross Lam selection-1 $\times$ Parbhani Kranti (often spelled Parvani Kranti). It has resistance to Yellow Vein Mosaic Virus (YVMV). Thus, A matches with I.
2. Pusa Sawani (B): This is a widely grown variety developed from the cross Pusa Makhmali $\times$ IC1542. It was initially resistant to YVMV and is suitable for both spring-summer and rainy seasons. Thus, B matches with IV.
3. Prabhani Kranti (C): This variety was developed to introduce YVMV resistance from the wild relative Abelmoschus manihot into the cultivated species through the cross Pusa Sawani $\times$ A. manihot. Thus, C matches with III.
4. Punjab-8 (D): This variety was developed as a mutant from Pusa Sawani using physical mutagens, offering improved tolerance to YVMV and fruit borer. Thus, D matches with II.
Combining these matches gives: A - I, B - IV, C - III, D - II.

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