Hu Fengyi, a professor at Yunnan University (YNU), and his team, together with related teams at home and abroad, recently published a research paper entitled Sustained Productivity and Agronomic Potential of Perennial Rice in internationally-renowned academic journal Nature Sustainability.
They also published a research brief entitled Switch to Perennial Rice Promotes Sustainable Farming.
The research paper and brief explain in detail Hu's team's exploration of the cultivation, improvement, and application of perennial rice over a period of more than 20 years.

Perennial rice plays an active role in improving society and the economy, promoting the sustainability of agricultural production systems, and maintaining ecological security, and has strong application potential.
The innovative research of perennial rice will help maintain food security and ecological integrity, and has important implications for other perennial food crop research.
So far, Hu's team has successfully bred a number of perennial rice varieties, which have been successfully tested and promoted in China and surrounding countries.
Perennial Rice 23 (PR23) was approved as a variety in 2018. It is highly-adaptable, has a stable yield, and is highly-perennial. It is a milestone in the field of perennial food crops based on interspecific hybridization.
