Embodiment 1
[0017] 1) The immature embryos of the two lines of sterile line FueS1 and restorer line 9311 were induced to form callus by in vitro tissue culture ( references : 1 Zhao Chengzhang; Zheng Kangle; Qi Xiufang. Effects of Paclobutrazol on Callus Induction, Differentiation and Strong Seedling Culture of Immature Rice Embryos. Acta Botanica (English Edition), 1990, Issue 05; 2 Chen Zhang; The relationship between the change of free amino acid pool and redifferentiation in tissue subculture.

Master's degree thesis of Fujian Agriculture and Forestry University, 2003); With 11Gy dose of 60 Co-γ ray irradiated the callus, planted the irradiated callus and cultured M 1 R 1 Seedlings (Fu eS1 planted in an artificial climate box), mixed harvest at maturity 1 R 1 Seeds on plants (M 2 R 2 );
[0018] 2) M of Fu eS1 and restorer line 9311 2 R 2 After the seeds were d...
Embodiment 2
[0021] 1) The immature embryos of two lines of sterile line Pei'ai 64S and restorer line E32 were induced to form callus by in vitro tissue culture, and a dose of 15Gy 60 Co-γ ray irradiated the callus, planted the irradiated callus and cultured M 1 R 1 Seedlings (Fu eS1 planted in an artificial climate box), mixed harvest at maturity 1 R 1 Seeds on plants (M 2 R 2 );
[0022] 2) Pei'ai 64S and E32 M 2 R 2 After the seeds are dried, they are hulled into brown rice, and extra-small-embryo mutant brown rice grains are visually selected from the brown rice; the extra-small-embryo mutant brown rice grains of Pei'ai 64S and E32 are planted respectively (Pei'ai 64S mutant brown rice grains are planted in an artificial climate box), Using the original parents Pei'ai 64S and E32 as controls, the agronomic traits and flowering and pollination traits of all mutants were investigated at the heading and flowering stage, and the yield traits of all mutants were investigated at the m...
Embodiment 3
[0025] 1) The immature embryos of two lines of sterile line Guangzhan 63S and restorer line R2469 were taken to induce callus formation by in vitro tissue culture, and a dose of 13Gy 60 Co-γ ray irradiated the callus, planted the irradiated callus and cultured M 1 R 1 Seedlings (Fu eS1 planted in an artificial climate box), mixed harvest at maturity 1 R 1 Seeds on plants (M 2 R 2 );
[0026] 2) Widely occupy the M of 63S and R2469 2 R 2 After the seeds are dried, they are hulled into brown rice, and the extra-small-embryo mutant brown rice grains are visually selected from the brown rice; the extra-small-embryo mutant brown rice grains of Guangzhan 63S and R2469 are planted respectively (Guangzhan 63S mutant brown rice grains are planted in an artificial climate box), Using the original parents Guangzhan 63S and R2469 as controls, the agronomic traits and flowering and pollination traits of all mutants were investigated at the heading and flowering stage, and the yield ...
