भारत सरकारने ___ व ___ ह्या दोन गहू जाती देशातील अन्नधान्य उत्पादन वाढविण्यासाठी आयात केल्या.

The correct answer is Option A (Sonara 64 and Lerma Rajo 64).

Key Points:
• In 1965-66, on the threshold of the Green Revolution, Agriculture Minister C. Subramaniam and agricultural scientist Dr. M.S. Swaminathan imported 18,000 tonnes of semi-dwarf, fertilizer-responsive wheat seeds from Mexico.
• The Mexican Dwarf Varieties:
• Developed by Nobel Laureate Dr. Norman Borlaug at CIMMYT (Mexico) using the Japanese *Norin-10* dwarfing gene.
• The two imported wheat varieties were Sonora 64 and Lerma Rojo 64-A.
• These varieties responded heavily to chemical fertilizers and irrigation without lodging, catalyzing unprecedented wheat yields in Punjab and Haryana.
• Later, ICAR bred amber-grained domestic hybrids like *Kalyan Sona* and *Sonalika* from these parent stocks.
• Therefore, Option 1 (Sonara 64 and Lerma Rajo 64) is the historically celebrated answer.
• Key Takeaway: India launched the Green Revolution in 1965-66 by importing Mexican dwarf wheat varieties Sonora 64 and Lerma Rojo 64.
