  Chinese landraces were found to have a slightly higher genetic diversity than inbred lines by Li et al., 2010. Specific locus amplified fragment sequencing (SLAF-seq) has been used by Han et al., 2015 to study the genetic history of the domestication process, perform genome-wide association studies (GWAS) of agronomically relevant traits, and produce high-density linkage maps. An SNP array was developed by Song et al., 2013 and has been used for research and breeding; the same team applied their array in Song et al., 2015 against the USDA Soybean Germplasm Collection and obtained mapping data that are expected to yield association mapping data for such traits.
  
  Rpp1-R1 is a resistance gene against soybean rust. Rpp1-R1 is an R gene (NB-LRR) providing resistance against the rust pathogen Phakopsora pachyrhizi. Its synthesis product includes a ULP1 protease.
  
  Qijian et al., 2017 provides the SoySNP50K gene array.
