Narrative

Seeds from octoploid and tetraploid wild plants from 110 populations were collected on public lands in the intermountain West in the fall of 2009. Seed zones were developed as described by Johnson and Vance-Borland (https://www.fs.fed.us/wwetac/threat-map/seedZones/doc/Johnson_2016_basin_wildrye.pdf). Seeds from 106 of the original populations, representing 12 seed zones, were planted for regeneration in 2016. Populations from each seed zone were planted together in plots 300 feet long and populations from each ploidy level (octoploid or tetraploid) were allowed to freely cross with one another. Each crossing block was separated from others by at least 50 meters. The number of populations varied with each seed zone, and the number of plants from each population varied to fit the length of the plots. Seeds from all plants were harvested in 2017 and bulked to form each seed zone accession. For LECI.tetra.4 there were 3 populations from basin wildrye seed zone 4 and approximately 195 plants from each population. The seed zone map may be found at: https://www.fs.fed.us/wwetac/threat-map/seedZones/doc/LECI%20seed%20zones%20Fig%202.pdf
