Abstract:

The central region of Shanxi Province is very important for wheat production. Understanding the major mineral elements concentration of these cultivars and core parents will provide useful information for wheat nutritional breeding. The iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) of 17 varieties/lines were investigated by an inductively couples plasma atomic emission spectroscopy (ICP-AES). The results showed that the 4 mineral elements content appeared to have a great variation, the mean grain content of Fe, Zn, Mn, Cu was 38.19 mg/kg, 29.30 mg/kg, 38.44 mg/kg and 6.89 mg/kg. The grain Fe content of three cultivars (‘Hedongwumai526’, ‘Jindong8’ and ‘Donghei10’) were over 45 mg/kg, ‘Tai10604’ showed the highest Zn accumulation (42.98 mg/kg). Two cultivars carried Mn content more than 45 mg/kg, and ‘Jinmai66’, ‘Donghei10’ were rich in Cu. Significant positive correlations between the concentrations of Mn and Fe (r= 0.58), Mn and Zn (r=0.69), but not significant between the other elements. It was indicated that genotypes screening with high concentrations of mineral elements from wheat cultivars was effectively. Four cultivars (‘Hedongwumai526’, ‘Jindong8’, ‘Donghei10’ and ‘Tai 10604’) could be used as parents of enriched with Fe and Zn in grains for wheat breeding program.
