Step 1: Understanding the Concept:
The Indian Council of Agricultural Research (ICAR) coordinates a network of national institutes, directorates, and research centers to conduct crop-specific research across different agro-climatic zones in India.
Step 2: Detailed Explanation:
Let us identify the headquarters of each ICAR research institute:
1. Central Potato Research Institute (CPRI) (A):
CPRI was established in 1949 and is located in Shimla, Himachal Pradesh. This location is well-suited for potato breeding because the cooler climate suppresses aphid vectors, helping maintain virus-free seed stocks.
Thus, (A) matches with (III).
2. Indian Institute of Rice Research (IIRR) (B):
Formerly known as the Directorate of Rice Research (DRR), IIRR was upgraded to a national institute and is headquartered in Hyderabad, Telangana.
Thus, (B) matches with (I).
3. National Institute of Plant Biotechnology (NIPB) (C):
Formerly known as the National Research Centre on Plant Biotechnology (NRCPB), this research institute is located on the campus of the Indian Agricultural Research Institute (IARI) in Pusa, New Delhi.
Thus, (C) matches with (IV).
4. Indian Institute of Maize Research (IIMR) (D):
ICAR-IIMR is a premier institute dedicated to maize research and is located in Ludhiana, Punjab.
Thus, (D) matches with (II).
Step 3: Final Answer:
The correct matching sequence is (A)-(III), (B)-(I), (C)-(IV), and (D)-(II). This corresponds to option (C).
