Genetic diversity in the BRIDG6 parents and six-row spring barley in the National Small Grains Collection Core. (A) The proportion of variants differing between Rasmusson (the common parent) and each BRIDG6 donor parent. Donor parents are sorted from the greatest (top) to least (bottom) genetic distance from Rasmusson. Analysis was conducted using 588,482 GBS SNPs prior to filtering steps required for subsequent analyses. (B) Principal component analysis (PCA) of the BRIDG6 parents and 1172 six-row National Small Grains Collection Core accessions, which are plotted as small gray open circles. Rasmusson, is plotted as a large black open circle, and BRIDG6 parents are open circles colored by subpopulation assignments in orange (Admixed), purple (Asian), green (Central European), blue (Coastal Mediterranean), red (East African), and dark gray (Unassigned). Analysis was conducted using 6648 iSelect 9K SNPs. (C) PCA of the BRIDG6 donor parents and 6059 recombinant inbred lines. BRIDG6 parents and the population are colored as described in (B), except large points represent parents and small points represent the population. Analysis was conducted using 5332 GBS SNPs with maximum 10% missing data.
