Median joining networks derived from reconstructed DNA sequence haplotypesof VvTFL1A . Network analysis was carried for haplotypes identified for 70polymorphic sites in the VvTFL1A gene excluding recombined haplotypes.Haplotypes are represented by circles with circle size proportional tohaplotype frequency (circle size corresponding to haplotype numbers of 1, 5 and25 are illustrated). The haplotypes colours relate to the accessionsclassification according to according to structured genetic groups (Additionalfile 1). Black dots represent mutational steps.Colour lines represent the mutations in LD that separated the three haplogroupsidentified (HG).
