Two complementary studies, appearing in HortScience, from Rutgers University are advancing the potential of amaranth (Amaranthus spp.) as a valuable leafy green by combining detailed morphological characterization with evaluations of horticultural performance and nutritional quality. Amaranth is gaining attention as a versatile crop with strong adaptability, rapid growth and high nutritional value.
The first study provides a comprehensive assessment of morphological diversity across a wide range of amaranth genetic resources, documenting variation in plant architecture, leaf shape, color and growth habits. This characterization establishes a foundation for identifying distinct traits that can be leveraged in breeding and crop improvement programs.
The second study builds on this foundation by evaluating multiple Amaranthus species and accessions for their suitability in leafy green production. Researchers assessed key horticultural traits such as yield, growth rate and harvestability, alongside nutritional attributes including mineral content and other health-promoting compounds.
