  1. In Experiments 13WS and 14 DS QTL lines were separated into two maturity groups (E: early and L: late). SDM: shoot dry mass. Mean values ± se (n = 3–4) are presented. Letters indicate significant difference groups within each experiment. n.a.: not applicable because the genotype was not included in the experiment. Actual values of SDM (g m−2) are presented in Additional file 1: Table S4
