| Abstract: |
| To determine the low-cumulative wheat varieties suitable for planting in the Cd pollution risk area of acidic brown soil in Shandong, 20 local wheat cultivars were selected as specimina, and field experiments were conducted to analyze the differences in grain Cd accumulation of the 20 wheat cultivars. The results showed that the Cd content in wheat grains ranged from 0.013 mg·kg-1 to 0.116 mg·kg-1. Furthermore, the enrichment and transport coefficients were significantly different（P<0.05）, among different varieties, the maximum enrichment coefficient is more than 9 times the minimum value, and the maximum transfer coefficient of different parts of wheat is 2-5 times the minimum value. Based on cluster analysis, enrichment coefficient, transport coefficient, and other indicators, 3 wheat varieties （Yannong 745, Jimai 55, Jinuo 116）exhibited low accumulation characteristics under experimental conditions, while the results of wheat yield indicated that 2 of them were higher than the average output. Combined with health risk evaluation indicators, two Cd low-accumulation wheat varieties with higher yields（Yannong 745, Jimai 55）were finally determined. Thus, the present study suggests Cd low accumulation wheat varieties for the safe utilization of local acidic brown soil Cd contaminated arable land. However, further studies are required to confirm the stability of the selected wheat cultivars with low Cd accumulation and the key influencing factors. |
