Downstream Analysis of SNPs from the SolCAP Tomato Infinium Array


Sung-Chur Sim, The Ohio State University; Heather L. Merk, The Ohio State University; John McQueen, Oregon State University

During this webinar, delivered to a live audience at the 2011 Tomato Disease Workshop at Cornell University in Ithaca, New York, Dr. Sung-Chur Sim from The Ohio State University discusses working with the tomato Infinium and genomic data.

The workshop webinar , Downstream Analysis of SNPs from the SolCAP Tomato Infinium Array, discusses the use of Infinium array data to improve tomato varieities. The SolCAP Cluster File v1 for the tomato Infinium array will be released to the public in the workshop. An emphasis will be placed on steps that can be taken to develop a subset of SNPs  as a cost-effective genotyping approach for mapping populations. The workshop is intended to be practical by providing demonstration with “hands on” examples.

At the end of the module, participants should be able to retrieve the SolCAP Cluster File, identify polymorphic SNPs in a specific mapping population, find the physical map locations of SNPs via BLAST, and select non-redundant and informative SNPs.

SolCAP Cluster File

Please read before accessing the pre-publication tomato cluster file.

The Solanaceae Coordinated Agricultural Project (SolCAP) is pleased to share a pre-publication tomato cluster file for use by research teams representing public and private interests as a resource to facilitate high-throughput genotyping.

The cluster file is based on genotyping the SolCAP tomato collection ( We caution that the cluster file is limited by the germplasm analyzed to date. The SolCAP collection is heavily biased toward inbred lines. Thus heterozygous calls were underrepresented in the data used to create this version. We encourage you to independently verify the genotype calls based on this file.

This cluster file is made available pre-publication with the understanding that users will respect the rights of those who developed the array and cluster file for publication. Consistent with current practices for release of sequence data (, we are making this cluster file available to the community to use for research purposes. By downloading the file, you agree to not publish a global analysis or description of the SolCAP Infinium array prior to its publication by SoLCAP in a peer reviewed journal. Any use of the cluster file should acknowledge and credit the “Solanaceae Coordinated Agricultural Project”. SolCAP is in the process of writing a manuscript on the array.
