Location: University of Missouri, Horticulture and Agroforestry Research Center (HARC) in New Franklin, MO
Principal Investigators: Mark Coggeshall, Jeanne Romero-Severson
A full sibling population was created, representing two nut cultivars in the University of Missouri (MU) germplasm repository, 'Sparrow' and "Schlessler'. The population consists of 323 seedling full sibs (all derived from the 2008 seed years), plus both parents. Full sibling status was confirmed via paternity exclusion genetic testing on all individuals. This paternity exclusion (PE) work was initiated in 2009 and primarily funded through the University of Missouri Center for Agroforestry (UMCA), in cooperation with the Romero-Severson (JRS) lab at the University of Notre Dame (ND).
Phenotyping of this of this population will be initiated in the spring 2015 and will include:
A second full-sib population totaling 135 to date, sharing the female parent “Sparrow” with the first population, was started at UM in 2015. The seed parent Sparrow was selected for whole genome resequencing at UC-Davis for a USDA Specialty Crops Research Initiative (SCRI) project headed by David Neale. Data is expected sometime in 2016.

Preliminary Genomic Characterization of Ten Hardwood Tree Species from Multiplexed Low Coverage Whole Genome Sequencing. PloS one. 2015 Dec 23;10(12):e0145031.
In order to develop SSR resources for ten important North American hardwood tree species, we individually barcoded and multiplex sequenced DNA from ten hardwood forest tree species using short reads produced from an Illumina HiSeq. Raw reads can be downloaded from the NCBI short read archive, project SRP021923. Bioinformatic processing included trimming, assembly, SSR identification and primer design, processing details including scripts are available.
