Figure 5.
Genetic determinism of the high germination rate encountered in the mutants tt2, tt4, and tt7. The time course of germination after 16 d of dry storage is presented. The parent mentioned first was used as female parent and the second as pollen parent. Seeds from a bulk of nine siliques derived from crosses were used. In A, ○, Ler; ▵, Ler × Ler; □, Ler × tt2; ●, tt2; ▴, tt2 × tt2; ▪, tt2 × Ler. In B, ○, Ler, ▵, Ler × Ler, □, Ler × tt4; ●, tt4; ▴, tt4 × tt4; ▪, tt4 × Ler. In C, ○, Ler, ▵, Ler × Ler; □, Ler × tt7; ●, tt7; ▴, tt7 × tt7; ▪, tt7 × Ler.
