Physio-biochemical and molecular characterization of a rice drought-insensitive TILLING line 1 (ditl1) mutant.

Drought stress is a major abiotic stress that limits rice yield. Therefore, the development of new varieties tolerant to drought stress is a high priority in breeding programs. In this study, 150 rice M mutant lines, previously developed using gamma-ray irradiation, were used, and a drought-insensitive rice mutant (ditl1) was selected by drought stress screening.
