In the frame of the PLANT-KBBE2008 " GrapeReSeq " project, an high throughput genotyping Illumina Infinium chip (20K) has been developed.

GrapeReSeq Consortium FAQ (Illumina)


A dataset obtained from the genotyping of a Vitis vinifera cultivated pool (using the SNPs of the 20k chip): see here


Development of a cluster file

A cluster file has been developed from the genotyping of 2278 individuals, 1450 from the Vitis vinifera species and 828 from different Vitis species or interspecific hybrids.


  • The current cluster file with all the SNP. The SNP that we found failed are flagged "AUX=2" in the SNP table provided above (GrapeReSeq_SNP_Table_all_180413.xlsx). The SNP with problematic clusters may give acceptable results in specific populations. They are flagged "AUX=3 to 9" in the SNP table.
