To solve the central problem of the long breeding time of rice and other crops, Prof. Yang Qichang’s research team takes the lead in finding out the environmental and biological characteristics of shortening the rice growth cycle. They have created dynamic co-regulation technologies of environment & nutrition for rice growth at different stages and established a technical method to significantly shorten the rice growth period. In the plant factory condition, a breakthrough has been achieved in rice speed breeding: the generation time of dwarf rice is halved, and the dwarf rice can be harvested at around 63 days. This technology can significantly improve rice breeding efficiency by adding 5–6 generations per year, thereby greatly accelerating the breeding speed of new varieties. This breakthrough provides a new technical approach to vitalize the seed industry and guarantee national food security.
