Correction: genetic dissection of photoperiod response based on GWAS of pre-anthesis phase duration in spring barley.

There are errors in the formatting of Table 1. Please see the correct Table 1 here.

The following errors appear in the body of the article.

In the second paragraph of the Introduction, PSEUDO-RESPONSE REGULATOR (HvPRR37) should be PSEUDO-RESPONSE REGULATOR 37 (HvPRR37).

There are errors in the sixth sentence of the Materials and Methods subsection titled “Phenotyping.” The correct sentence is: To avoid any mineral deficiency each pot was additionally fertilized with 1.5 gram of solid fertilizer (that constitute minerals 17:11:10/N: P: K).

There are errors in the fourth sentence of the Results subsection titled “Identification of marker-trait association within the ppd-H1-carrying group.” The correct sentence is: However, HvCO1 resides in a chromosomal region, which physically contains three other CO-like family members (HvCO12/ HvCO13/HvM and HvCO15) and the circadian clock-related genes, HvLHY/HvCCA1.

There are errors in the twelfth sentence of the fourth paragraph in the Discussion subsection titled “Heading time genetic network models.” The correct sentence is: Similar conclusions can be drawn from gene clusters on chromosome 4H, which besides HvCO16 also includes HvPRR59, HvPhyB and HvPrr73 (see 4H; 51.1–51.4 cM), 5HS (including HvC)3, HvTFL1, HvCMF13; 43.7–51.6 cM) and 1HS (HvCMF10; 41.1–48.2 cM).

There are errors in the fourteenth sentence of the fourth paragraph in the Discussion subsection titled “Heading time genetic network models.” The correct sentence is: Another group-specific effect was found for SNPs around the FT-like homolog HvFT2 and the circadian clock-related gene HvGI (3HS; 45.8–52.0 cM).

There are errors in the third sentence of the sixth paragraph in the Discussion subsection titled “Heading time genetic network models.” The correct sentence is: Although its genetic position strongly suggests that the strongest associations reside very close to HvCO1 (supported by 13 SNP markers; see Figure 9), we cannot completely rule out that linkage with other CO genes in this region like HvCO12/ HvCO13/HvM and HvCO15 (Figure 7) contribute to this effect.
