  • Original line (variety “Simon”) from which the selected lines were derived.

  • Energy use efficiency = NAD(P)H content/respiration.

  • §Five locations, six repetitions/location, 3 years.

  • One location with sandy soil and moderate drought stress, 2 years.

  • One location with loamy soil, 3 years.

  • *, P < 0.05; **, P < 0.01; and ***, P < 0.001 versus control.
