Aofuyou 287 is a rice variety bred by Hunan Aopulon Technology Co., Ltd. It meets the national standards for rice variety approval and has been officially approved. This variety is suitable for single-season mid-season rice cultivation in the paddy-growing areas of Sichuan Province’s plains and hilly regions, Guizhou Province (excluding the Wuling Mountain area), the low- and mid-altitude indica rice zones of Yunnan Province, Chongqing Municipality (excluding the Wuling Mountain area) at elevations below 800 meters, and the southern rice-growing region of Shaanxi Province—provided that these areas are free from severe blast disease. Planting is not recommended in regions where blast disease is severely prevalent. The total growth period is 152.0 days; plant height is 122.3 cm; panicle length is 25.5 cm; effective panicles per mu amount to 127,000; 1,000-grain weight is 26.1 g; and grain quality meets the Grade II standard of the agricultural industry. In 2020, the rice produced from this variety won the Silver Award at the Second “Seed Cup” High-Quality Rice Evaluation Competition. In 2024, random inspections of the crop seed market in Xingwen County revealed a germination rate of 92%, moisture content of 11.6%, and compliance with GMO testing requirements. This variety has been designated as a leading agricultural variety for 2025 in Anshun City, Zhenning County, and Shibing County of Guizhou Province, and in the 100-mu ultra-high-yield demonstration plot in Xianjiaba Village, Fucheng District, it achieved the expected yield of 700 kg per mu. In 2024, large-scale cultivation in Dewang Township, Jiangkou County, yielded an average of 1,000 jin per mu, while yield measurements in Yutang Township translated into a dry-weight yield of 645 kg per mu.
