Step 1: Understanding the Concept:
Under the Indian Council of Agricultural Research (ICAR), several crop-specific institutes and bureaus manage research and germplasm collections across different states.
Step 2: Detailed Explanation:
Let us analyze both statements:
Assertion A:
The ICAR-Indian Institute of Sugarcane Research (IISR) is located in Lucknow, Uttar Pradesh.
The institute located in Coimbatore, Tamil Nadu, is the ICAR-Sugarcane Breeding Institute (SBI), which is famous for its historical role in the hybridization and "nobilization" of sugarcane.
Thus, Assertion A is false.
Reason R:
The ICAR-National Bureau of Plant Genetic Resources (NBPGR), which is the nodal organization in India for managing plant genetic resources, was established in 1976 and is headquartered in New Delhi.
Thus, Reason R is true.
Step 3: Final Answer:
Assertion A is false, but Reason R is true.
Therefore, the correct option is (D).
