  1. aR = Resistance (symptoms include systemic necrosis, mainly due to unprotected I gene); S = Susceptibility (systemic mosaic from lack of I gene or any recessive resistance genes).
  2. bNumber of lines screened with markers SW13, KASP, and CAPS in this study.
  3. cAutomated genotype calls obtained from data of BARCBEAN6K_3 SNP BeadChip.
  4. dMarker present = +; marker absent = -.
  5. eKASP genotype calls. A = homozygous for SNP allele A; G = homozygous for SNP allele G.
  6. fThe CAPS marker yields two alleles. The resistant allele has two bands (201 and 110 bp), whereas the susceptible allele has a single band (311 bp). A = homozygous for resistant allele II; B = homozygous for susceptible allele ii.
