Figure 5. Evolution of embryo/kernel ratio (A), embryo oil concentration (B) and kernel oil concentration (C) of kernels located at the middle of the ear, from DK752xDK752, DK752x5MG, and 5MGx5MG crosses. Lines indicate the models fitted to the data. For embryo/kernel ratio: Embryo/kernel ratio = a + b TT, for TT 
c; embryo/kernel ratio = a+ bc +d (TT – c), for TT > c and TT e; Embryo/kernel ratio = a +bc+ d (e-c), for TT > e. For DK752xDK752: a = –9, b = 0.039, c = 461, d = 0.0084, and e = 868 (R2 = 0.98, n = 77); for DK752x5MG: a = –11.5, b = 0.050, c = 441, d = 0.012, and e = 901 (R2 = 0.98, n = 77); for 5MGx5MG: a = –12.9, b = 0.058, c = 461, d = 0.017, and e = 846 (R2 = 0.99, n = 10). For embryo oil concentration of Dk752xDK752 and DK752x5MG: Embryo oil concentration = a + b TT, for TT c; embryo oil concentration = a + bc +d (TT – c), for TT > c and TT e; embryo oil concentration = a + bc + d (e – c), for TT > e; For DK752xDK752: a = 206.5, b = 0.38, c = 546, d = –0.24, and e = 912 (R2 = 0.75, n = 76); for DK752x5MG: a = 232.3, b = 0.41, c = 536, d = –0.23, and e = 878 (R2 = 0.67, n = 76). For embryo oil concentration of 5MGx5MG: Embryo oil concentration = 175.5 + 0.61 TT, for TT < 448°Cd; embryo oil concentration = 448 mg g–1, for TT 
448°Cd. For kernel oil concentration of K752xDK752 and DK752x5MG: Kernel oil concentration = a + b TT, for TT < c. Kernel oil concentration = a + bc, for TT < c. For DK752xDK752: a = 20.4, b = 0.057, and c = 531 (R2 = 0.67, n = 77); for DK752x5MG: a = 7, b = 0.118, and c = 548 (R2 = 0.87, n = 77). For kernel oil concentration of 5MGx5MG: Kernel oil concentration = a + b TT, for TT c. Kernel oil concentration = a + bc + d (TT – c), for TT > c and TT e. Kernel oil concentration = a + bc + d (e – c), for TT > e where a = 6.8, b = 0.159, c = 542, d = 0.042, and e = 923 (R2 = 0.96, n = 10).
