The researchers studied high-quality inbred rice varieties in Guangxi from 2000 to 2011. They found that while rice quality has improved, amylose content is still low. Some scented rice varieties with high quality and yield were developed. Production of high-quality rice increased, but disease resistance needs improvement. To enhance breeding, they suggest focusing on long-grain rice with specific qualities, using existing high-quality varieties, and investing in better breeding techniques. The goal is to increase rice yield and quality through innovation and modern biotechnology.
