Three rice cultivars and several F3 lines selected from F3 segregation lines of crosses Milyang23/Tong88-7 and Milyang23/TR22183 were used to study the effects of cold tolerance on the response of grain quality to cold water irrigation. Cold water irrigation resulted in the decrease in rice grain size. The length, length-width ratio and weight of brown rice grain were more sensitive to cold water irrigation than grain width and thickness.
