SGS IF TraitGenetics announces improved and cost-efficient SNP genotyping array panels for field crops

Genotyping of field crop species using Single Nucleotide Polymorphisms (SNPs) is an important tool for breeding improved varieties through marker-trait-association studies, genomic selection, genetic relationship analyses, and marker-assisted backcrossing. The TraitGenetics Section of SGS Institut Fresenius GmbH offers now new and improved SNP genotyping arrays based on marker quality, genome position and haplotype structure for:

Wheat

The new 26K Wheat array contains all markers from SGS IF TraitGenetics' widely used 25K Wheat array plus 844 functional markers from new sources including published trait-specific markers. The new 8K wheat array, that contains a subset of markers from the 26K Wheat array, has been improved by 404 functional new markers.

Maize

The new 27K Maize array contains all markers from the previous 25K Maize array plus 2,364 functional new markers from different sources. The new 9K Maize array, that contains a subset of the 27K Maize array markers, has been improved by the addition of 915 functional markers.

Soybean

The new 6K Soybean array contains all markers from the previous 5K Soybean array and has been improved by 228 functional new markers that are either linked to specific traits or complement the array with important markers from other published arrays.

Brassica

The new 20K Brassica array contains markers from the previous 19K Brassica array and has been expanded through the addition of 1,375 functional markers from other published sources. The new 5K Brassica array contains a subset of the 19K array markers which has been expanded in comparison to the previous 4K Brassica array by 861 functional markers.

Barley

The new 16K Barley array has been improved by the addition of 759 functional markers to the previous 15K Barley array. The new 5K Barley array contains a subset of the 15K array markers and has been expanded in comparison to the previous 4K Barley array by 1,212 functional markers.

Sunflower

The new 11K Sunflower array has been improved by the addition of 1,108 functional markers to the previous 10K Sunflower array.

Cotton

The new 18K Cotton array contains markers derived from the Cotton 63K Illumina HD array and a subset of markers from the new 30K USDA Cotton array.

Oat

The new 8K Oat array contains all markers from the previous 7K Oat array and has been improved by 1,133 functional markers from the 3K USDA Oat array providing now an overlap of nearly 2,000 markers with this 3K USDA array.

Rye

The new 6K Rye array contains a selection of high-quality markers from the 600K Axiom Rye array and has been improved by the addition of 1,014 new markers, including candidate genes.

Triticale

The new 32K Triticale array contains all markers from the improved 26K Wheat array combined with the improved 6K Rye array (in total 1,823 new functional markers compared to the previous 30K Triticale array).

Sorghum

The 9K Sorghum array contains 8,677 markers derived from the Sorghum 50K Illumina array.

The analysis with SGS IF TraitGenetics' improved arrays will be offered to customers at essentially identical prices as for the previously available SNP genotyping arrays for the respective crop. They also provide interesting alternatives to the discontinued Illumina HD arrays for some of these crops.
