(CHR) Chromosome. 1The percentage accounted for the total segregation-distorted markers. 

2

(HH) Homozygous genotype for the alleles from Triticum dicoccoides accession H52; (LL) homozygous genotype for the alleles from Triticum durum cultivar Ldn, (HL) heterozygous genotype for the two alleles from H52 and Ldn, respectively. (H) HH + HL; (L) LL + HL. 

3

(H) Allele from T. dicoccoides accession H52; (L) alleles from T. durum cultivar Ldn. The frequencies were estimated based on the ratio of homozygotic marker genotypes in the F2 generation.
