Yuefeng A was the first high quality indica wild-type sterile line with no chalky rice bred in China. After introduced, the principle of reciprocal traits such as parents’ quality was used, and the line R6 547 with high quality restorer was used to achieve the genetic trait of parents Allelopathic, high-quality hybrid indica hybrid FengYouXiang accounting, the nine indicators of rice quality ministerial quality rice level one standard, two indicators of ministerial quality rice two standards, the output level of 600kg / mu, strong resistance It is of great significance to promote the quality of domestic rice and the industrialization of high-quality rice seeds.
