Breeding method of rice genic male sterile line for fixing rice hybridization advantage

The invention provides a breeding method of a rice genic male sterile line for fixing rice hybridization advantages, which comprises the following steps: by taking a rice sterile plant 5090 as a male parent and a rice sterile plant 1240 as a female parent, carrying out cross breeding to obtain a rice genic male sterile line XS for fixing the rice hybridization advantages. The rice two-line sterile line XS cultivated by the method has the characteristic of enabling part of filial generations to be quickly homozygous, the F2 generation is not separated after the XS is hybridized with parents such as Xiang78s, Xiang86s and Red 35s, the heterosis can be fixed, multiple generations are not separated after being cultivated, and the success of'one-line hybrid rice 'is realized. F2 to F6 are still not separated when the rice genic male sterile line XS for fixing the rice hybridization advantage is hybridized with parents such as Xiang78s, Xiang86s and Red 35s, and the heterosis of the parents is kept. 本申请提供一种用于固定水稻杂交
