Relationship between shoot vigour and rhizosheath size. Rhizosheath size (mg mm–1 root length) was measured in the five lines from each of the recurrent selections and plotted against width of the third fully emerged leaf (shoot vigour). The error bars represent SEs for both leaf width and rhizosheaths (n=18 for rhizosheaths and n=24 for leaf width).
