In 1944, Borlaug moved to Mexico to work on breeding high-yield, disease-resistant strains of wheat. Mexico adopted them — and in 1970, wheat yields were six times what they had been in 1950. In 1965, India and Pakistan, then on the brink of widespread famine, began growing the high-yield wheat. Over the next 30 years, wheat yields in India tripled. The same happened with high-yield rice strains that had been developed in the Philippines.
