Research Project: 2xcelerate: A Diploid Inbred Line Strategy to Accelerate Genetic Gain in Potato

Location: Vegetable Crops Research

Project Number: 5090-21220-005-10-A
Project Type: Cooperative Agreement

Start Date: May 30, 2015
End Date: Jul 31, 2019

Objective:
1. Create six diploid recombinant inbred line (RIL) populations in potato. 2. Phenotype and genotype the RIL populations and their founders. 3. Produce homozygous diploid S. tuberosum potato lines.

Approach:
Our project will generate 100 recombinant inbred lines (RILs) from each of six genetically diverse founder parents carrying germplasm from wild and cultivated potato relatives. We will evaluate the RILs in field trials and create a dense set of DNA markers. The RILs will be provided to the US Potato Genebank as true seed populations, accompanied by the phenotype and genotype data. This RIL set will be a novel, powerful, and valuable public resource for the mapping of economically important traits and the development of markers for marker-assisted selection. In addition, we will create inbred lines of cultivated potato for use in DNA sequence analyses and the generation of additional inbred line germplasm resources such as introgression lines. Our project will provide the foundation for future research to develop diploid potato cultivars.
