Mutated winter wheat lines were screened for improved drought resistance compared to the wildtype by withholding water for 3 weeks after 9 weeks of normal growth, and noting their responses upon re-watering. Of the 146 mutants grown, 73% were either killed due to water stress or showed poor recovery, while 27% recovered better than the wildtype line. This experiment enabled the selection of candidates for further investigation to better understand the genetic basis of drought tolerance in winter wheat.
