摘要

Amaranth is a widely consumed leafy vegetable known for its high mineral and nutrient content, which provides numerous health benefits. The present study aimed to evaluate the nutritional, pigment, and mineral diversity of Indian Amaranthus genotypes to identify promising lines for leafy vegetable improvement and micronutrient-rich breeding. A total of 96 genotypes from eight Amaranthus species were evaluated using an augmented block design. Samples were collected in triplicate for the analysis of bioactive compounds (chlorophylls and vitamin C), antioxidant pigments, and minerals. The study found significant variability in total chlorophyll (16.92–58.05 mg/100 g), vitamin C (41.07–141.9 mg/100 g), crude fibre (1.14–14.05%), calcium (1.16–5.67 mg/g), phosphorus (0.96–10.12 mg/g), and potassium (0.89–10.03 mg/g). The VRAM-7, VRAM-56 and Sel-4 genotypes were especially high in calcium, magnesium, zinc, iron and manganese. The genetic analysis revealed moderate to high genotypic and phenotypic coefficients of variation, as well as high heritability, implying that many of these traits are controlled by additive genes. The Principal Component Analysis identified total chlorophyll, chlorophyll a, and betaxanthins as significant contributors to variation. Cluster analysis separated genotypes into six distinct clusters, with Cluster II excelling for bioactive compounds and Cluster IV and VI in mineral traits. The study found significant genetic diversity among Indian amaranth genotypes, providing valuable resources for breeding nutritionally rich cultivars for leafy vegetable consumption.
