Distribution of introgression segments in the CSSLs on the 26 chromosomes. a Physical map was constructed by SSR markers; b Physical map was constructed by whole-genome re-sequencing SNPs. Each row indicates a CSSL, and each column represents a chromosome. The black and red squares denote the homozygous donor segments from Gb; the light-gray and green represent the heterozygous from Gb; the grey background represents the genetic background of the Gh
