The Correct Option is A
Solution and Explanation
Step 1: Understanding semi-dwarf rice varieties.
Semi-dwarf rice varieties were developed during the Green Revolution to increase yield and reduce lodging.
Step 2: Role of IRRI.
The International Rice Research Institute (IRRI), Philippines, developed several improved rice varieties.
Step 3: Identifying correct variety.
IR-6 is a semi-dwarf rice variety developed for high yield and fertilizer responsiveness.
Step 4: Conclusion.
Semi-dwarf rice varieties were developed from IR-6 in the Philippines.
