      abstract     = {The selection of wheat genotypes according to their drought
                      tolerance is essential to off-season cultivation. The
                      objective of this work was to characterize wheat genotypes
                      through yield and components, morphological characteristics
                      under water stress, and irrigated water use efficiency in
                      the Cerrado region in Brazil. Genotypes were planted during
                      the winters of 2016 and 2017 since there is no precipitation
                      during this season and water levels can be measured. They
                      were then submitted to four water regimes: WR1, WR2, WR3,
                      and WR4, representing 100 $\%,$ 83 $\%,$ 50 $\%,$ and 30
                      $\%$ of evapotranspiration replacement. The following
                      variables were evaluated: peduncle length (PL), number of
                      ears m−2 (NE m−2), hectoliter weight (HW), thousand
                      grain weight (TGW), drought resistance index (DRI),
                      irrigated water use efficiency (IWUE) and yield. Most
                      variables showed correlation with yield and can be a useful
                      tool for breeding programs. PL and HW were best correlated
                      with yield. BRS 264 (irrigated biotype) was productive in
                      treatments receiving the greatest number of irrigation
                      treatments. Given that WR1 registered the highest water
                      level, it was not expected that the rainfed biotype (BR18)
                      would show a higher yield than an irrigated biotype
                      (BRS254). BRS404 (rainfed biotype) was the most productive
                      under moderate stress treatment (WR3). Aliança (rainfed
                      biotype) showed a higher yield under severe stress. Rainfed
                      biotypes presented a higher DRI than the irrigated ones.
                      These genotypes can be used as a reference in breeding
                      programs under each water regime in which their performance
                      was outstanding. None of the variables studied contributed
                      to the selection of the most efficient wheat genotypes in
                      the IWUE.},
