Correction to: Heredity (2010) 105, 235–243; doi:10.1038/hdy.2010.39; published online 14 April 2010

The authors have discovered an error that they would like to correct. Figure 3, Characterization of 12 S-locus mutants, shows two markers (RP81E18 and P9SP1) at distances of <0.5 and 0.5 cM, respectively. The actual distance for marker RP81E18 is <0.05 cM, and that for marker P9SP1 is 0.05 cM, as correctly indicated in the text.

The authors apologize for this error.
