Figure 1

(a) Densities of 25,804 genotyping-by-sequencing markers in the reference bread wheat genome (RefSeq v1.0). The color key with marker densities indicates the number of markers within a window size of 10 Mb. (b) Population structure analysis of 55,568 lines. The plot of the first two principal components explaining 5.8% and 5.2% of the variation, respectively indicated weak population structure with high relatedness between the lines in the Stage 1 (S1) panels across crop cycles 2013–2014 (referred to as S1 1314) to 2018–2019 (referred to as S1 1819).
