An intermediate wheatgrass (Thinopyrum intermedium) Nested Association Mapping (NAM) population was evaluated at the University of Minnesota Agricultural Experiment Station in St. Paul, MN and The Land Institute in Salina, KS for two years (2017 and 2018). The population (n = 1,168 with both phenotype and genotype data) consisted of ten families where each progeny shares one common parent and was planted in a RCBD design with two blocks surrounded by a border plant. The phenotypic dataset includes 33 traits ranging from morphological, maturity, yield components and domestication traits, and a note column which indicates whether the plants were later identified as selfs and/or other observations. The genotype data was derived from genotyping by sequencing and includes over 8,000 SNP markers. The consensus genetic map was created in JoinMap and used for linkage mapping both within and combined across populations.
