Fig. 2. Consensus sequences for winter and spring genotypes of the region amplified by VRN-A1-specific primers (indicated in bold-italic letters at the beginning and end of the sequence). Dots in the sequence from the spring varieties indicate identical bases with the sequences from the winter varieties. The three differences found between the s and w haplotypes are indicated by bold letters. AciI restriction sites are underlined. The location of the allele specific primer 361W-F is indicated in underlined italic letters.
