摘要

In response to climate change, rapid population growth, and increasing pressure on agricultural lands, amaranths have emerged as promising crops owing to their exceptional nutritional profile, rich bioactive compounds, climate resilience, and high yield potential. To optimize their role as a sustainable food source, comprehensive studies on their agronomic performance and phytochemical properties are critical. This study evaluated the diversity in agronomical traits, seed morphology, and phytochemical contents among 59 amaranth accessions from ten different species across six continents, with the aim of identifying promising candidates for nutraceutical applications and breeding programs. The agronomic traits showed wider variations, each with a coefficient of variation (CV) exceeding 10.00%. Among the morphological traits, the color channels including red, green, and blue, showed the largest diversity with CVs exceeding 45.00%. Contents of δ-tocopherol, γβ-tocopherol, α-tocopherol, total tocopherols, and squalene were in the ranges of 0.00–29.58, 15.50–141.03, 0.00–32.25, 29.74–148.31, and 764.35–3892.00 mg/kg, respectively. Analysis of variance showed significant variations among the amaranth species for all analyzed parameters, except circularity, roundness, δ-tocopherol, and squalene (p < 0.05). In contrast, the difference in origin significantly affected days to flowering, color channels, α-tocopherol, and squalene. Principal component analysis identified important traits with significant contributions to the overall diversity. Likewise, hierarchical clustering on principal components grouped the accessions into three distinct clusters. Correlation analysis revealed key associations between the analyzed traits. Overall, the study revealed substantial phenotypic diversity among amaranths and identified promising accessions for nutraceutical and breeding use. Moreover, species and origin could be used as parameters to distinguish amaranth germplasm based on targeted phenotypic traits.
