Abstract:
Globally, pea (Pisum sativum L.) is an important temperate legume crop for food, feed, and fodder, and many breeding programs exist to develop cultivars adapted to these end uses. In order to manage and utilize genetic resources for pea improvement, the USDA Pea Single Plant Plus Collection (PSPPC), which contains 431 Pisum accessions with morphological, geographic, and taxonomic diversity, was assembled. To maximize the value of this collection for trait mapping and genomics-assisted breeding projects, detailed genetic characterization was performed. To that end, genotyping-by-sequencing―a cost-effective method for de novo SNP marker discovery―was used to generate 66 591 high-quality SNPs. These data allowed us to identify accessions divergent from mainstream breeding germplasm that could serve as sources of novel, favorable alleles. In particular, a group of accessions from Central Asia appeared nearly as diverse as a sister species, P. fulvum, and subspecies, P. sativum subsp. elatius. Accession genotypes can be paired with new and existing phenotype data for trait mapping; as proof-of-concept, Mendel’s A gene controlling flower color was localized to its known position. SNP data were also used to define a smaller core collection of 108 accessions with similar levels of genetic diversity as the entire PSPPC, resulting in a smaller germplasm set for research screening and evaluation under limited resources. Taken together, the results presented in this study along with the release of a publicly available SNP data set comprise a valuable resource for supporting worldwide pea genetic improvement efforts.
