Axiom® Strawberry Genotyping Array by Affymetrix, Inc.

Axiom® Strawberry Genotyping Array was designed through the Affymetrix® Expert Design Program in collaboration with the International RosBREED SNP consortium that spans multiple nations, states, and institutions dedicated to genetic improvement of rosaceous crops. The array offers genome-wide coverage of polymorphic SNPs across the cultivated garden strawberry hybrid (Fragaria × ananassa).

Axiom Strawberry Genotyping Array requires advanced analysis. Genotyping many different varieties together may create multiple clusters during the analysis that interfere with each other and/or blend the clusters together. Genotype calls are not provided for multi-allelic SNPs.


Axiom® Strawberry Genotyping Array Features:

• Comprehensive content - 95,062 SNPs and indels derived from octoploid and diploid cultivars, including:
  - 1,761 multi-allelic SNPs
  - 3,751 SNPs derived from diploid cultivars; the remaining markers are derived from octoploid cultivars
• Multiple cultivars represented - SNP discovery was facilitated with a diverse worldwide breeding germplasm panel that included:
  - Holiday, Korona, and F1 seedlings from the cross Holiday x Korona 
  - Two likely diploid progenitors, Fragaria mandschurica, F. iinumae
  - One known diploid F. vesca

Axiom® Strawberry Genotyping Array Applications:

• QTL discovery.
• Identify traits of economic significance.
• Genome-wide scanning.
• Marker-assisted breeding.
• Accelerate and increase efficiency of cultivar development.
• Identify the presence of important markers in existing strawberry germplasm.
• Use genetic information to identify germplasm that will perform well in specific growing regions.
