摘　　要：Rice is one of the most important staple food for over half the world's population.New evidence from the Food and Agriculture Organization shows that the number of hungry people in the world is growing,reaching more than 690 million in 2020.It is an urgent task to increase crop production to feed the people suffering from chronic hunger in the world.The Green Revolution of the 1960s boosted cereal yields through widespread adoption of semi-dwarf varieties and extensive use of inorganic fertilizers(Khush,2001).Today,the most productive Green Revolution varieties(GRVs)of rice and wheat in the world retain semi-dwarf phenotypes,which have several advantages over tall traditional varieties:(1)they have a lower center of gravity of the plant body,which decreases the risk of lodging and allows farmers to apply excessive fertilizers to obtain high yield;(2)they have an increased harvest index,which enables plants to allocate more energy and resources to seed production。
