Since then?， he has spent? much of his time researching and developing new varieties. In 1973, together with other scientists, he succeeded in developing hybrid rice. The introduction of this new product made China a leader in rice production. For this, he became known as the“Father of Hybrid Rice”. In 1980, the technology for hybrid rice was introduced to the United States and, later, to many other countries around the world. Because of Dr. Yuan's hard work, China now produces? enough rice every year to feed its people. Now Dr. Yuan is working on developing? super hybrid rice.
