1964 first put forward the idea of cultivating "sterile line, maintainer line and restorer line" to make use of rice heterosis, and carried out scientific experiments.

1970, he and his assistants Li Bihu and Feng Keshan discovered a male sterile wild rice in Hainan, which became the key to break through the "three lines" matching. ?

1972 bred the first rice male sterile line "Erjiunan 1 A" and the corresponding maintainer line "Erjiunan 1 B" in China, and bred the first strong combination "Nanyou No.2" in the following year, and studied a set of seed production techniques.

1986 puts forward the strategic assumption that hybrid rice breeding is divided into "three-line method using interspecific heterosis, two-line method using interspecific heterosis and one-line method using distant heterosis". Known as "the father of hybrid rice" by peers.

Yuan Longping once said that he had two dreams: one was to enjoy the cool under the grass. In my dream, rice grows as tall as sorghum and its seeds are as big as peanuts. Another dream is to realize my dream of rice yield per mu 1000 kg as soon as possible.

To some extent, these two dreams are as unpretentious as the soil he has dealt with all his life. This is also his greatness. In his dream, there are no fancy concepts, no dazzling theories, and no anxiety around core journals. There is only one heart to share the worries for the people.

In his dream, science should be the driving force of social progress. It is the power of this belief that has become the driving force for him to persist.

At the age of 87, he is still running around in the fields, tirelessly solving various specific problems. Yuan Longping has been at the forefront of rice breeding for decades, which is no accident, no distractions, and has just reached the other side of her dream.

Starting from the fundamental interests of all mankind, not from individuals, I have just realized my personal dream. Yuan Longping said, "My dream is simple", but it turns out that this simple dream has solved the problem of feeding hundreds of millions of people in the world.
