It has excellent nutritional value and ample capacity for growth under drought, heat, and soil nutrient deficiency. The objective of this study was to characterize and quantify genetic diversity among a series of 178 mostly Peruvian amaranth individuals genotyped from among 48 accessions using 96 biallelic single nucleotide polymorphism (SNP) markers in KASPar assays on a 96.96 Fluidigm EP1 platform. The 178 seed genotypes included the predominant white-opaque (waxy), white-vitreous (nonwaxy), black, and brown types, all from within the Centro de Investigacion de Cultivos Andinos-Universidad Nacional de San Antonio Abad del Cusco collection. The samples separated into two groups based on the seed color parameter (black, brown, and white-vitreous versus white-opaque) with STRUCTURE analysis but did not form distinct genotypic groups based on geographic origin. When analyzed as seed-color subgroups—black vs. brown vs. white-vitreous vs. white-opaque—83.46% of the genetic variation was explained by genetic differences within subgroup. The highest average observed heterozygosity (Ho) within color-based subgroups was 0.2612 in the vitreous-seeded subgroup, and within-group expected heterozygosity (He) was highest in the brown-seeded subgroup (0.398). Cluster analysis and principal component analysis partitioned the amaranth accessions into two clusters with four distinct subclusters. Analyses also revealed evidence for selection of nonwaxy, vitreous-seeded amaranth in the Andes.
