aTrait: RL = Root length (cm), RDW = Root dry weight (g), RV = Root volume (cm3), TIL = Tiller number per plant, GH = Growth habit.
bChromosome number.
c,dLeast square means of the S42IL and Scarlett, respectively.
eRelative trait performance of the S42IL compared to Scarlett, calculated as RP(S42IL) = [Lsmeans(S42IL) – Lsmeans(Scarlett)]/Lsmeans(Scarlett).
