Bangladesh is rich in genetic diversity of crops specially rice. Thousands of rice cultivars including indigenous, locally popular, aromatic and modern HYVs are available in Bangladesh for many years. Rice is a potential source of micronutrient specially zinc, iron etc and bioavailability of these minerals exclusively depend on the content of Phytic acid (PA) and relative molar ratio of Phytate to minerals accordingly. We aimed to explore for such valuable information for popular rice varieties specially BRRI HYVs in Bangladesh. We profiled mineral composition for Zn, Fe, Ca, P and anti-nutrient components such as PA and molar ratio of PA to minerals for 68 HYVs including Aus, Aman and Boro seasons in Bangladesh. Our date reveals that BRRI dhan43 possess the highest Zn content of 38.4 ppm followed by Fe (17 ppm), Ca (68.1 ppm) and P (2.5 gKg-1) at clean rice condition. We also noticed that it’s molar ratio to Zn (PA/Zn); Fe (PA/Fe); Ca(PA/Ca) and P(PA/P) are lower among all selected high Zn enriched HYVs by 3.56, 6.93,1.24 and 25.69 respectively. Since there is no single HYV reported yet, BRRI dhan43 might be a potential micronutrient enriched BRRI HYV for Aus season and it could be used as parental source for zinc enriched rice (ZnER) breeding in Bangladesh.
