Table 3 Features of the 20 linkage groups

From: Construction of a SNP-based genetic linkage map in cultivated peanut based on large scale marker development using next-generation double-digest restriction-site-associated DNA sequencing (ddRADseq)

  1. The number in parentheses is represents the number of SSR anchor loci in the linkage group.
  2. aSDRs, segregation distortion regions.
  3. ‘Gap ≤ 5’ indicates the percentages of gaps in which the distance between adjacent markers was smaller than 5 cM.
