Abstract:

In this study, to screen out functional rice varieties suitable for cultivation in southern Shandong Province, eight rice varieties were selected as experimental materials, and the protein, iron, zinc and selenium were quantitatively detected through variety suitability investigation and plot test. Survey results showed that each test variety had normal characteristics. Although the differences between the varieties were quite obvious, the varieties could adapt to the climate in southern Shandong Province, and the plant type of ‘Changlixiang’ was compact, the tillering ability of ‘Crystal No.1’ and ‘Daliangnuo No.1’ were strong, and the resistance of each variety to the four main diseases in Southern Shandong Province was relatively good. The results showed that ‘Heixiang DL-1’ had the best content of functional elements, ‘Daliangnuo No.1’ had relatively high content of protein and iron, and higher content of selenium than that of common varieties. ‘Crystal No.1’ could be planted as iron rich variety, ‘Crystal No.2’ and ‘Yueguang’ could be planted as zinc rich variety, and ‘Changlixiang’ could be developed as selenium rich variety.
