There are multiple advantages of KASP™ SNP markers when compared to SSR/STR/microsatellite markers:

  • Faster analysis times
  • Scalable for high throughput applications such as large-scale screening protocols
  • Simpler data analysis, more robust and reproducible
  • Cost savings1

The process

SNP markers have many advantages in their application and can unlock the power of high-throughput molecular breeding techniques. However, the conversion process requires several steps and considerations:

  1. SNP discovery: Discovery of SNP markers in flanking regions of targeted SSR/STR/microsatellite or other genomic regions with targeted genotyping by sequencing (GBS) or enzyme restriction-based GBS for SNP discovery.
  2. Validation of trait association: Validation by Biosearch Technologies is required to confirm the discovered SNP markers can be associated to the same traits as the original SSR/STR/microsatellite marker.
  3. Assay design service: Biosearch Technologies' assay design services for discovered SNP markers for either PCR-based or NGS-based genotyping methods
  4. High throughput genotyping: Using KASP or BHQ PCR-based assays or targeted genotyping by sequencing (Flex-Seq™)

The customer can also consider optional implementation of Biosearch Technologies' laboratory automation systems to enable high throughput extraction and genotyping in-house.


The SNP discovery service is ideal for:

  • Co-dominant SNP genotyping
  • Genetic diversity analysis
  • Genetic mapping
  • Mapping to whole genome sequence
  • Discovery of (rare) SNP variants
  • Genome wide association mapping
  • Genomic selection
  • Fingerprinting
  • Marker-assisted selection
  • Population genotyping
  • Marker-assisted backcrossing
  • Characterising training/reference populations
  • Molecular mapping
  • Marker-assisted recurrent selection
  • QTL mapping


For targeted methods such as PCR-based genotyping and targeted GBS services, a reference genome is required to design the appropriate SNP-specific primers.

If no reference genome is available for your species of interest, there are two options that can be implemented prior to the steps outlined above.

  1. Biosearch Technologies can support with NGS sequencing to develop a reference genome, or:
  2. Biosearch Technologies can offer enzyme restriction-based GBS services to discover new SNP markers without a reference genome.

Knowledge about the traits of the species of interest and capacity to validate these traits and their association to the SSR markers will be required. For your reference, you can see a list of species that we have worked with here.
