Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
Panama wilt is a classic example of how pathogen evolution (races) can force shifts in agricultural production. The question asks to identify the susceptibility patterns of major banana varieties.
Step 2: Detailed Explanation:
• Gros Michel and Race 1 (A): In the first half of the 20th century, Gros Michel was the dominant export banana. It was decimated worldwide by Race 1 of the fungus. Thus, A is True.
• Cavendish and Race 1: The Cavendish variety was adopted because it was resistant to Race 1. Thus, Statement B and E are false.
• Cavendish and Race 4 (C): In recent decades, a new, virulent strain called Tropical Race 4 (TR4) has emerged. Cavendish bananas are highly susceptible to TR4, threatening the current global banana supply. Thus, C is True.
Final Answer:
Statements A and C represent the core historical and contemporary facts about Panama wilt. Option (D) is correct.
