The paper overall reviewed the research progress of genetic rule, varieties breeding, seed industries of rice in 2020—2022 in China, briefly comparied the research difference in China and abroad, prospected the research trend and direction. In terms of research on the evolution of rice varieties, it was found that high yield, plant morphological dominance, and resistant haplotypes resistant to biological stress are critical factors for extensive area planting of primary types of indica rice, while early maturity and resistant haplotypes resistant to abiotic stress are vital factors for vast area planting of primary varieties of japonica rice; The world's first redesigned and rapidly domesticated tetraploid rice were created, achieving a breakthrough of "from 0 to 1" and opening up a new direction for crop breeding; An intelligent rice breeding navigation program has been developed, with great potential for application in the rapid cultivation of new rice varieties; Many new breeding theories and methods have been innovated, and several new breeding techniques have been invented. Over the past three years, 6 177 varieties (sterile male lines) have been bred and approved, 61.4% of which were bred by enterprises.
