Singh D.R., and Singh S., 2016, Fruit attributes, phyto-nutrients profiles and antioxidant activity of Noni (Morinda citrifolia L.) genotypes in Andaman Islands, Genomics and Applied Biology, 7(13): 1-10 (doi: 10.5376/gab.2016.07.0013)

The study aimed to indentify genotypes of Noni (Morinda citrifolia L.) for higher recovery of phyto-constituents and with superior fruits. Tested 33 genotypes showed significant (p<0.05) variation in total carotenoids (114.7-696.3 mg/100 g), polyphenols (165.4-370.3 mg/100 g), ascorbic acid (71.0-98.2 mg/100 g) and tannin (88.9-395.2 mg/100 g) and micronutrients Mn (4.6-284.2 ppm), Mg (16.3-1131.3 ppm), Ca (51.1-6815.6 ppm) and Cu (2.9-17.2 ppm). Fruit traits also significantly varied in the tested genotypes as observed for average fruit weight (50.5-117.9 g), number of seeds per plant (90.0-221.0) and pulp recovery (35.0-50.0%). Correlation analysis showed strong correlation between carotenoids and ascorbic acid (r=0.973; p<0.05) and flavonoids (r=0.691; p<0.05). Antioxidant activity also showed positive correlation with carotenoids (r=0.0335; p<0.05), flavonoids (r=0.249; p<0.05), Cu (r=0.953; p<0.05) and Mn (r=0.953; p<0.05). The study identified FRG-14, JGH-5, TRA-1, TRA-2 and HD-6 genotypes as rich in phytochemicals and micronutrients for commercial utilization.
