Wheat genotyping library
Wheat genotyping assay library - choose from >8,000 functionally validated wheat KASP SNP assays. Cost-effective, easy to run, no minimum order.
Wheat (Triticum spp.) is one of the world’s most important cereal crops. The association of single nucleotide polymorphisms (SNPs) in wheat is challenging due to its large and complex genome, yet SNP markers have the potential to significantly enhance the ability to create new wheat varieties through marker assisted selection (MAS).
LGC, Biosearch Technologies’ wheat genotyping library utilises our accurate and robust PCR-based KASP genotyping chemistry. The library consists of two sets of functionally validated SNP markers developed in conjunction with the University of Bristol (UK), and the Integrated Breeding Platform (IBP), respectively. In total, we provide over 8000 pre-validated KASP SNP assays that breeders and scientists can use for the development of precision breeding in wheat hybrids. Bespoke sets of assays can be conveniently selected with the Assay Search Tool.
Unlike chip-based systems with fixed marker sets, our wheat genotyping library allows flexible selection of informative markers, and easy adaptation to changing germplasm collections in individual breeding programmes. Furthermore, KASP genotyping assays are highly cost-effective, thus providing an economical option to use the same SNP assays throughout the course of a breeding programme.
Biosearch Technologies’ complete solution also encompasses plant sample collection kits, extraction and genotyping services, enabling breeders even in remote locations to apply MAS.
Bristol wheat genomics assays
This set of over 7000 functionally validated assays has been developed in conjunction with the University of Bristol, School of Biological Sciences (see press release). Extensive information about this project can be accessed from the Bristol Wheat Genomics site, in the CerealsDB section. Development of the Bristol wheat library is described in the following publication:

The core set of wheat KASP assays
Within the Bristol wheat library, a core set of 960 pre-validated assays have been identified that are evenly distributed at 10 cM intervals throughout the wheat A, B and D genomes. The even distribution of the 960 assays facilitates medium resolution screening, e.g. for characterisation of parental varieties and development of novel varieties in breeding programs.
The wheat library assays cover the A, B and D genomes, and all chromosomes within these genomes. There is a file listing the assays separately by genome (A, B and D) available for download here.
