Diversity and population structure of Nordic potato cultivars and breeding clones.

ABSTRACT:

Background

The genetic diversity and population structure of breeding germplasm is central knowledge for crop improvement. To gain insight into the genetic potential of the germplasm used for potato breeding in a Nordic breeding program as well as all available accessions from the Nordic genebank (NordGen), 133 potato genotypes were genotyped using the Infinium Illumina 20 K SNP array. After SNP filtering, 11 610 polymorphic SNPs were included in the analysis. In addition, data from three important breeding traits - percent dry matter and uniformity of tuber shape and eye - were scored to measure the variation potato cultivars and breeding clones.

Results

The genetic diversity among the genotypes was estimated using principal coordinate analysis based on the genetic distance
