Researcher Deng Huafeng is the main pioneer and founder of temperature sensitive two-line hybrid rice, the leader of Yuan Longping's hybrid rice innovation team, the director of the National Hybrid Rice Engineering Technology Research Center, the chief scientist of the National Japonica Rice Engineering Technology Research Center, the first batch of national ten thousand person plan science and technology innovation leading talents, the first batch of national level talents of the "One Hundred and Ten Million" talent project in the new century, and experts enjoying national special allowances; He has been awarded the National exemplary individual, National Excellent Scientific and Technological Worker, China Youth Science and Technology Award, Hunan Guangzhao Science and Technology Award, Yuan Longping Agricultural Science and Technology Award and other honorary titles.

The discovery of temperature sensitive genic male sterile material for the first time has led to the development of the world's first indica rice temperature sensitive genic male sterile line, Annong S-1, providing a key genic male sterile gene resource tms5 for two-line hybrid rice. The invention of temperature sensitive two-line hybrid rice technology has opened up new avenues for utilizing hybrid advantages and promoted the development of crop genetics and breeding. We have created practical thermosensitive male sterile lines and breeding techniques for thermosensitive hybrid rice. We have created 8 practical thermosensitive male sterile lines such as 810S and Shuang1S, and cultivated 76 new thermosensitive two-line hybrid rice varieties such as Baliangyou 100 and Shuangliangyou 138. Among them, 810S is the first practical thermosensitive nuclear sterile line and Baliangyou 100 is the first thermosensitive two-line hybrid rice, playing an important leading role in the development of thermosensitive two-line hybrid rice. We have created a hybrid rice quality improvement technology with both parents having excellent quality, small differences in quality traits, and low sensitivity to the environment. We have bred 13 national approved high-yield varieties of second grade high-quality rice or above, such as Shuangliangyou Taizhen and H-liangyou 532, which are first-class high-quality rice, achieving coordinated development of quality and high-yield. We have taken the lead in researching and creating a technical system for breeding thermosensitive male sterile lines using high altitude natural low temperatures, as well as a new technology for producing core seeds of thermosensitive male sterile lines using natural low temperatures. This has solved the dual problems of difficult reproduction and unsafe seed production, providing technical support for the rapid and stable development of the two line method. Hosted the collaborative research on hybrid japonica rice, established high-quality and high-yield hybrid japonica rice breeding technology, bred and promoted the hybrid japonica rice Tianlongyou 619 with high seed production yield and first-class quality, solving the problem of low seed production yield and poor quality, which is a major breakthrough in hybrid japonica rice research.

Obtained 17 invention patents and 13 new variety protection rights; Hosted 10 major projects such as the National 863 Program and the Science and Technology Support Program; He It has won one special prize of national scientific and technological progress, one the State Technological Innovation Award and one national innovation team award respectively, and five provincial and ministerial awards such as the first prize of China Shennong Science and Technology Award; Published 5 monographs and over 150 papers.
