Effect of allelic variation at HvFT3 on flowering time of winter barley grown under different experimental regimes. Flowering time of two winter F4 families (Ppd-H1 vrn-H1 VRN-H2) carrying the spring (S) HvFT3 (black) or the winter (nonfunctional, W) hvft3 allele (red) was scored as days to heading after 8 weeks of vernalization in LD followed by LD (VLD_LD) and after 8 weeks of SD treatment followed by LD (SD_LD). Flowering time was measured in days from germination until heading. Each box represents the average flowering time of 10 plants. Error bars, standard deviation. Significant differences were calculated based on a Student’s t test. ***refers to a significant difference in flowering time at P < 0.001.
