Mean value ± SE of at least three replications. Every rice line used in this experiment was harvested in 2015. ^aThree fractions (Fr. I, II, III) were separated at the minima of the carbohydrate content curve detected with refractive index detectors. Fr. I, II, and III correspond to the apparent amylose content, amylopectin long chains, and amylopectin short chains, respectively. ^bData from Itoh et al. (2017). ^∗Significant differences between Kinmaze and other lines (t-test, P<0.05). ^∗∗Significant differences between Kinmaze and other lines (t-test, P<0.01).
