Since its publication, it has been brought to our attention that the source of genotypic data and description of the data processing used in this article were unclear. The authors have provided additional information to clarify this. In the Materials and Methods section, under the first subheading ‘Population, phenotypes and genotypes’ the second paragraph should read as follows:
The CCLONES population was genotyped using the Illumina Infinium assay (Illumina, San Diego, CA, USA; Eckert et al., 2010) with 7216 single-nucleotide polymorphisms (SNPs), each representing a unique pine expressed sequences tag (EST) contig. A total of 4825 SNPs selected based on quality and reliability of the genotyping calls, according to the beadstudio ver. 220.127.116.11 software (Illumina), were used in this study. Illumina’s GenTrain score was used as the initial criteria for quality control and selection of SNPs for genotyping – samples with GenTrain score < 0.7 were excluded from the analysis. Cluster data was then visually inspected to verify that discernible clusters could be observed. Next, data from SNPs that did not pass the initial selection criteria were analyzed for each family separately – the rationale for taking this approach is that family-specific polymorphisms in SNP-flanking regions could interfere with the Illumina assay. Families where distinct clusters could be identified for a given locus were genotyped. Allele frequency was not considered a criterion to discard SNPs. Genotypic data are publicly available at http://www.sfrc.ufl.edu/fbrc/CCLONES_genotypes and also via the Allele Discovery of Economic Pine Traits II FTP site http://loblolly.ucdavis.edu/bipod/ftp/Genotype_Population_CCLONES.txt
