  1. aTrait: RL = Root length (cm), RDW = Root dry weight (g), RV = Root volume (cm3), TIL = Tiller number per plant, GH = Growth habit.
  2. bThe means of S42ILs, ISR42-8 and Scarlett were calculated as an average of the phenotypic data for each trait across 2012 and 2013 for each treatment separately. Statistical differences across means are indicated with letters a, b and c.
  3. cStandard error.
