Material 1: "How productive can the land be?" Yuan Longping once had a very romantic dream: rice grows as tall as people, and people enjoy the cool under the harvested rice ears... In October 1965, when Yuan Longping wrote "Hybridization" When Mi Mi wrote his first paper, the academic community did not agree with it because the paper deviated from the classic theories at the time. Some people even ridiculed him for being whimsical. But Yuan Longping did not give up. After years of hard work, he overturned the prevailing international view that rice had no hybrid vigor and introduced generations of hybrid rice, which is known as the fifth greatest invention dedicated to mankind by the Chinese nation.

Material 2 The World Food Prize Foundation called him "one of the most important experts in the field of rice research in the world". "The hybrid rice that was the first to be successfully cultivated and widely planted in the world triggered a rice production revolution in China, increasing rice production in China." It has tripled in a century." The hybrid rice breeding approach thus spread widely from Asia and Africa to the Americas. In 2004, the Israeli Wolf Prize, the Thai Golden Sickle Prize, and the World Food Prize were successively awarded to Yuan Longping, a famous Chinese hybrid rice expert. The Wolf Prize is known as Israel's Nobel Prize, and the World Food Prize is the highest international honor in the field of agriculture.
