Assessment of the Genetic Diversity and Population Structure of the Peruvian Andean Legume, Tarwi (Lupinus mutabilis), with High Quality SNPs

Lupinus mutabilis Sweet (Fabaceae), “tarwi” or “chocho”, is an important grain legume in the Andean region. In Peru, studies on tarwi have mainly focused morphological features; however, they not been molecularly characterized. Currently, it possible to explore genetic parameters of plants with reliable and modern methods such as genotyping by sequencing (GBS). Here, for first time, we used single nucleotide polymorphism (SNP) markers infer diversity population structure 89 accessions from nine regions Peru. A total 5922 SNPs distributed along all chromosomes were identified. STRUCTURE analysis revealed that this crop grouped into two clusters. dendrogram was generated using UPGMA clustering algorithm and, like principal coordinate (PCoA), showed groups correspond geographic origin samples. AMOVA a reduced variation between clusters (7.59%) indicated variability within populations 92.41%. Population divergence (Fst) 1 2 low difference (0.019). We also detected negative Fis both populations, demonstrating that, other species, depends cross-pollination.
