Phyto-Nutrient Diversity in Morinda Citrifolia L. Genotypes of Andaman Islands, India

The Indian mulberry or Noni (Morinda citrifolia L.) is one of the emerging sources of natural antioxidants for herbal and pharmaceutical industry. The genus Morinda has more than 150 species in which M. citrifolia is identified as most important for health and economic point of view. Present study revealed significant (p < 0.05) diversity in 33 genotypes of M. citrifolia from Andaman and Nicobar Islands (India) for phyto-constituents. The promising genotypes viz. FRG-14, JGH-5, TRA-1, TRA-2 and HD-6 were identified for commercial uses. Correlation analysis in M. citrifolia germplasm showed strong correlation between carotenoids and ascorbic acid (r2 =0.973; p<0.05), tannin (r2 =0.598; p<0.05), flavonoids (r2 =0.691; p<0.05) and phenol (r2 =0.598; p<0.05). The genotypes showed wide range for antioxidant capacity which showed positive correlation with carotenoids (r2 =0.335; p<0.05), flavonoids (r2 =0.249; p<0.05) and Cu (r2 =0.953; p<0.05), Mn (r2 =0.953; p<0.05) and Mg (r2 =0.582; p<0.05). The diversity analysis is useful for designing breeding strategies for phyto-nutrient rich genotypes for better recovery in health products.
