Mineral diet quality index (M-DQI) of rice and wheat grain of their cultivars released along succeeding decades. (A–B) Rice. (C–D) Wheat. M-DQIe, M-DQIej, M-DQIek, M-DQIb, and M-DQIt represent M-DQI of essential, essential macro-elements, essential micro-elements, beneficial and toxic elements, respectively. Horizontal lines beyond the dashed vertical line extended up to 2040 represent projected M-DQI for rice and wheat cultivars released up to 2040. Data are mean (n = 6). Asterisks indicate significant differences between the observed means of the decades for the cultivars of rice and wheat released up to 2000s and 2010s, respectively (*P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001).
