A potato mapping population and framework genetic map:
tools for breeders and complex trait analysis
Potato genome sequence
The first whole genome sequence of potato crop was put together by the Potato Genome Sequencing Consortium (PGSC), and published at 2011 . The genome comes from a double monoploid individual called DM1-3 516 R44 (DM), which was derived from another culture of a heterozygous diploid (2n=2x=24) S. tuberosum group Phureja clone (PI 225669).
Genetic map linked with the genome sequence
The 2x backcross progeny CIP308328 ((DM X DI) X DI) was developed by crossing the homozygous (DM) as female with the heterozygous diploid S. tuberosum Stenotomum Group (formerly S. stenotomum ssp. goniocalyx germplasm accession CIP703825 (DI) as male, and crossing the resulting hybrid CIP305156.17 (DMDI) again to DI as male parent. The mapping population ”DMDD” consisting of 180 individuals was used to construct a genetic linkage map for anchoring the genome sequence . The progenitors and the progeny individuals are available for international distribution from CIP.

Trait evaluations for QTL mapping
DMDD segregates for numerous morphological, reproductive, physiological and biochemical traits which combined with the high density genetic map and the high quality reference genome sequence open up great opportunities for trait-QTL and gene discovery studies. To date we have evaluated the population for reproductive traits, yield components, mineral content, abiotic stress tolerance, as well as various morphological traits of flower, fruit, leaf, stem and tuber. See the full data dictionary of traits evaluated here. We are open for collaboration and research ideas. Please contact Merideth Bonierbale for further information.
