Correction to: Novel SNP markers in InvGE and SssI genes are associated with natural variation of sugar contents and frying color in Solanum tuberosum Group Phureja.

Correction

After the publication of this work [1], we detected some mistakes in the reverse primers of InvGE and BMY-8/2 and in the forward primer of PWD shown in Table 1. Additionally, we made some editions in the primer sequences from Additional files 2 and 3. Please see the corrected Table 1 and Additional files 2 and 3 below.

Amplicon sequences of candidate genes with associations to sugar contents and frying color in Solanum tuberosum Group Phureja with the SNP alleles and SNP positions in the potato reference genome (version 4.03) [28, 43]. The sequences were retrieved from the SPUD data base [44]. Primer sequences are underlined, markers with associations are highlighted in blue and SNPs previously reported for tetraploid potatoes are shown in italics. The numbers indicate the position of the sequence and the SNPs in the chromosomes (chr). Exonic regions are represented with red letters while introns are represented in black letters according to the gene models from the SPUD data base [44]. (DOCX 23 kb)
