The rice variety Yangguang 800 was selected from Zhendao 88 as the female parent and Huangjin-qing as the male parent. It has compact plant type, strong tillering ability, high ear-setting rate, high seed setting rate and moderate tolerance to rice blast. The quality of rice reaches the national standard of high quality, the husk is thin, the rice yield is high, the rice grain is transparent, there is no abdominal white, and the rice quality is excellent. It is suitable for high quality and high yield cultivation by machine intercalation or light simplified cultivation by wide strip direct seeding in early season. In this paper, the characteristics of Yangguang 800 have been systematically summarized, and the demonstration and application of light and simplified technology of Yangguang 800 have been carried out in practical production, and good results have been achieved.
