This study aims to distinguish three dragon fruit species well adapted to Andaman and Nicobar Island through morphological (34 quantitative and 26 qualitative traits), biochemical (5 traits) and molecular (14 ISSR primers) characterization. Morphological characterization revealed that presence of considerable amount of genetic variations among them especially for fruit characters viz., colour of peel and pulp. Cladode characters such as number of spines (3\u20135), length of areoles (mm) as 1\u20134, margin ribs of cladode (convex or concave) and its waxiness (weak or strong white waxy or light waxy) could be used for identification of three\n                    <jats:italic>Hylocereus<\/jats:italic>\n                    spp. under present study. Highest co-efficient of variation (%) obtained for pulp weight (88.7), whereas, lowest in distance of anthers belowstigma (3.3). Fruit and pulp weight (g) ranged from 26.5\u2013419.3 and 10.3\u2013258.8 with mean value of 204.8 and 125.3, respectively. Comparatively, high phenol (71.3\u2013161.3) and flavonoid (26.6\u2013508.2) content observed in peels than pulp (32.5\u2013130.0 and 45.0\u2013258.2) of fruit indicating higher antioxidant potential.

DPPH-based scavenging activity (%) revealed higher scavenging activity of peels (55.6\u201381.2) than pulp (36.0\u201375.3) extracts. Comparatively, ABTS-based scavenging activity (%) was found more than DPPH-based one. Sixteen ISSR primers screened, 14 were produced 178 reproducible amplified bands. Number of amplified bands varied from 5 in UBC887 to 19 in UBC811 with an average of 12.71 bands per primer. Range of polymorphic bands and % polymorphism observed were 1\u201313 and 20.0\u201392.8, respectively. The polymorphic information content value of ISSR marker ranged from 0.42 (UBC895) to 0.91 (UBC 856).
