Show Hint
- A, B, C only
- B, D, E only
- C, D, E only
- A, C, E only
The Correct Option is A
Solution and Explanation
The international Green Revolution of the 1960s transformed agricultural productivity in developing nations.
Step 2: Detailed Explanation:
Core historical associations of the Green Revolution include:
1. Rockefeller and Ford Foundations (Statement A): Provided crucial international philanthropic funding and technical establishment of CIMMYT in Mexico and IRRI in the Philippines.
2. Mexico (Statement B): The experimental breeding base where Dr. Norman Borlaug developed semi-dwarf, lodging-resistant, rust-immune wheat lines using the Japanese Norin-10 dwarfing gene.
3. Wheat and Rice (Statement C): The primary staple cereal crops that experienced exponential yield breakthroughs.
Maize, barley, chickpea, and sugarcane were not the foundational crops of the initial Green Revolution breakthrough.
Step 3: Final Answer:
Hence, terms A, B, and C only are associated with the Green Revolution.
