The invention discloses a rice low-temperature-resistant related gene and application thereof in rice low-temperature-resistant breeding. The nucleotide sequence of the rice low-temperature-resistant related gene CT1 is shown as SEQ ID NO.1, and the coded amino acid sequence of the rice low-temperature-resistant related gene CT1 is shown as SEQ ID NO.2. A mutant plant of which the functional part is deleted or weakened is obtained by mutating the low-temperature-resistant related gene CT1 of the rice, so that the low-temperature resistance of a rice variety is improved, and the growth vigor of the rice variety under a low-temperature condition is improved. The rice low-temperature-resistant related mutant gene provided by the invention can improve the low-temperature tolerance of seedlings, a mutant plant with the function part of the gene SEQ ID NO.1 deleted or weakened is created through a gene editing technology, and a low-temperature-resistant strain with other excellent agronomic characters is screened o
