Figure 4.

Temperature and day-length dependence of bolting rates of F₃ families 112206 and 112210 which are homozygous for br₁. The parental accession 93161P was used as bolting control. Plants were vernalized at 4°C or 6°C under 16 h light and subsequently grown under 22 or 16 h light at 20°C. Asterisks indicate significant differences at p.adjust < 0.05 for each growth condition based on Pearson's chi-squared tests.
