Sugar profile of internodes in controls and selected progenies of the F₂ generation (Rio X L9). The first group (Rio-1 to 7) represents the parent Rio control, the second group LR24 (LR24-1 to 7) represents the transgene negative control F₂ progenies, and the rest three groups are PCR positive F₂ progenies from LR3, LR19 and LR20. The last digit in the label of the X-axis is the internode number counted from the top. G + F: ½ (Glucose plus fructose); Suc: Sucrose; IM: Isomaltulose. Sugars were measured 20-day post-anthesis in the middle section of each internode. Results were means with standard errors from three replicates. The horizontal line was drawn on the highest total sugar content among all internodes of the Rio control
