The study aimed at the effect of agronomic traits, yield and grain quality in rice mutant lines under water saving irrigation condition. This study also provides guidelines for selecting adapted rice lines under water saving irrigation conditions. The drought tolerant and susceptible lines used in this study are DR14, a drought mutant line that derived from CNY911303 mutation pool in Chiayi Agricultural Experiment Station, and HY3, a drought tolerant control line, and DR2, DR9, and DR34 susceptible lines, respectively. The rice drought experiment in this study used an intermittent irrigation approach during maximum tilling stage. The experimental results showed that rice yield and yield components have no significant difference, but plant height has become shorter under water saving irrigation. In addition, there is no effect on brown rice production rate, milled rice production rate, crude protein, and taste meter value under water saving irrigation, but the occurrence of other unmatured rice in brown rice has reduced. In addition, the rate of occurrence of chalky kernels in milled rice has increased. The rice yield under water saving irrigation shows that there are different adaptations among rice mutant lines. Among the DR14 has the best performance with stable and good adaptation because its yield was 4963 kg/ha and sterility rate was 6.3%.
