  1. Values are expressed as mean ± standard error of the mean
  2. aMeasurement in mm
  3. bMeasurement in mg
  4. cNote that at GS 85 and GS 92, caryopsis measurements include the palea and lemma and are therefore more accurately “grain” measurements
  5. “-” Indicates that measurements could not be made due to the growth stage
