Interaction effect between HvCEN and VRN-H1 on heading time in the Orria x Plaisant population, estimated in 5 field trials. The x-axis represents the average Julian days to flowering per trial. The additive effect of HvCEN represented in the y-axis is calculated as the average effect in flowering time when one HII allele is substituted by one HI allele. The solid line represents the HvCEN effect across heading times in the presence of the winter vrn-H1 allele. The dashed line represents the HvCEN effect across heading times in the presence of the reduced vernalization requirement VRN-H1-4 allele. The difference in flowering time between homozygous genotypes (HI-HII) would be double of the additive effect shown. Data reanalyzed from Mansour et al. (2014)
