Abstract: Twenty vegetable amaranth genotypes were evaluated for total antioxidant capacity, antioxidant leaf pigments, vitamins, and selection of suitable genotypes for extraction of juice in a randomized complete block design (RCBD) with three replications.  Vegetable amaranth was rich in chlorophyll,  β-cyanins, β-xanthins, betalains, carotene, ascorbic acid and total antioxidant.  The genotypes VA14, VA16, VA18, VA15, and VA20 could be selected as amaranth vegtable varieties with high yields and abundance antioxidant leaf pigments and vitamins to produce juice.  The genotypes VA13 and VA19 had above-average foliage yield and high antioxidant profiles while the genotypes VA2, VA3, VA9, VA11, VA12, and VA17 had a high antioxidant profiles and below-average foliage yield.  These genotypes could be used as a donor parent for integration of potential high antioxidant profiles genes into other genotypes.  The correlation study revealed a strong positive association among all the antioxidant leaf pigments, total antioxidant capacity and foliage yield.  Selection based on total antioxidant capacity, antioxidant leaf pigments could economically viable to improve the yield potential of vegetable amaranth genotypes.  Total carotene and ascorbic acid exhibited insignificant genotypic correlation with all the traits except total antioxidant capacity.  This indicates that selection for antioxidant vitamins might be possible without compromising yield loss.
