Abstract: Exploration of genetic resources for micronutrient concentrations facilitates the breeding of nutrient-dense crops, which is increasingly seen as an additional, sustainable strategy to combat globalmicronutrient deficiency. In this work, we evaluated genotypic variation in grain nutrient concentrationsof 20 Brazil wheat (Triticum aestivum L.) accessions in response to zinc (Zn) and Zn plus selenium (Se)treatment. Zn and Se concentrations in grains exhibited 2- and 1.5-fold difference, respectively, betweenthese wheat accessions. A variation of up to 3-fold enhancement of grain Zn concentration was observedwhen additionally Zn was supplied, indicating a wide range capacity of the wheat lines in accumulatingZn in grains. Moreover, grain Zn concentration was further enhanced in some lines following supply ofZn plus Se, showing stimulative effect by Se and the feasibility of simultaneous biofortification of Zn andSe in grains of some wheat lines. In addition, Se supply with Zn improved the accumulation of anotherimportant micronutrient, iron (Fe), in grains of half of these wheat lines, suggesting a beneficial role ofsimultaneous biofortification of Zn with Se. The significant diversity in these wheat accessions offersgenetic potential for developing cultivars with better ability to accumulate important micronutrients ingrains. |
