| Abstract: | Cold tolerant mutant at booting stage was developed from population M_2 generation after the dry seeds of a wide compatibility Japonica rice 02428 were irradiated with 300Gy of 60Co γ-ray. Seed setting rate of the mutant was characterized by stronger cold tolerance, and the cold tolerance did not turn weak under low temperature from M_3 to M_6.The mutant was named “02428c" at M_6. Compared with the parent variety 02428, the seed setting rate of the mutant was 72.34% higher, showing stronger cold tolerance. Genetic analysis revealed that cold tolerance of 02428c was controlled by one single dominant gene.= |
