•The InDel at −1,302  bp in the Ctb1 promoter enhances gene expression and cold tolerance.•The InDel improves rice cold adaptability at seedling and booting stages.•Incorporation of the InDel into NILs (NIL-Ctb1HapI) increases rice cold tolerance and yield.•The −1,302 fragment of InDel may be used a...
