  1. LG = IT93K-503-1 × CB46 RIL population linkage group based on AFLP + SNP map, Consensus LG = corresponding linkage group in the cowpea consensus genetic map, consensus map position represents position of the marker closest to the QTL peak based on mapping in the RIL population
  2. cM position on the consensus map and annotations for AFLP markers were not determined
  3. Mac-4 was included as a suggestive QTL since it did not meet the significance thresholds in either the Kruskal-Wallis or MQM analysis
