Minor allele frequency (MAF) of polymorphic cherry SNPs.

<p>MAF was determined in sweet cherry (n = 50) and sour cherry (n = 37) evaluation panels for 1825 and 2058 polymorphic SNPs, respectively.</p

SNP informativeness in sour cherry for the eight sets of chromosomes based on whether the SNP was derived from polymorphism in sweet cherry or in one of the two sour cherry subgenomes (i.e., <i>avium</i> or <i>fruticosa</i>).

<p>The 330 sour cherry accessions evaluated are listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048305#pone.0048305.s003" target="_blank">Table S3</a>.</p>a<p>Numbers of SNPs for the subgenomes of sour cherry are split (/) between <i>avium</i> and <i>fruticosa.</i></p>b<p>Numbers in parentheses are totals for RosCOS SNPs derived from sweet cherry and are included in the first number.</p

Workflow for SNP detection, validation, and final choice in development of the RosBREED 6K cherry SNP array v1.

<p>Stage 1 filtered 1.9 million cherry SNPs anchored to the peach genome to almost 40K SNPs. More stringent filtering criteria in Stage 2, guided by a prior validation step with a small SNP subset examined for a range of potential filters, putatively enriched the quality of the remaining 32K SNP pool. Finally, the 6K array SNPs were chosen from among stage 2 SNPs by attempting to achieve even genetic spacing over species genomes and subgenomes with pre-determined proportional allocations, after preferential inclusion of certain SNPs. ADT = Illumina's Assay Design Tool. MAF = minor allele frequency.</p

Outcomes of a GoldenGate® validation assay for a set of 144 SNPs screened with 160 cherry accessions to test potential filtering parameters.
