Abstract
Major dependence on wheat-based foods with low bioavailability of nutrients led to high malnutrition rates, especially in developing counties. Four wheat genotypes (Albelad (BE), Aldwasair (AD), Australia (AU) and Najran (NJ)) grown in Albaha region were analyzed for the first time for the variation in micronutrient (Se, Mo, Cu, Zn, Mn, Fe, B and Na) and macronutrient concentrations (P, Ca, Mg and K) in the whole wheat grain using Inductively coupled plasma mass spectrometry (ICP-MS) in order to select genotype of high nutritional value of the wheat for human consumption for further breeding by farmers. Substantial micronutrient variation existed among the four genotypes according to their mean Se, Mo, Zn, and Na concentrations, while macronutrient variation existed in their P and Ca concentrations. The NJ genotype appeared to contain higher concentrations of Se, Na, and Ca than the other genotypes while AU contained higher concentrations of Zn and P than AD, BE, or NJ. The results of this study can provide information about micro- and macro-nutrient enriched wheat genotypes for agricultural strategies aimed at improving the nutritional value of wheat plants.

Minerals are a huge group of chemicals that are considered very important for human health
This will improve the nutritional health of target populations by representing a wide range of diversity in the available gene pool and ensuring the human health impacts before advancing parerals required in small quantities) and by breeding or genetic engineering, requires ticular genotypes in breeding programs to macronutrients
Macro- and micronutrient composition of wheat genotypes common in Albaha region has been studied for the first time
Summary
Minerals are a huge group of chemicals that are considered very important for human health. Minerals are usually categorized into two groups, micronutrients (minenhanced yields, regardless of grain quality or nutrient content.[2] Biofortification has emerged as a new tool to enhance micronutrient concentrations via conventional and molecular plant breeding, genetic modification, and agronomic interventions involving suitable fertilizer applications.[7] Developing new genotypes biofortified with nutrients, grown in the Albaha region [namely, Albelad (BE), Aldwasair (AD), Australia (AU), and Najran (NJ)] This will improve the nutritional health of target populations by representing a wide range of diversity in the available gene pool and ensuring the human health impacts before advancing parerals required in small quantities) and by breeding or genetic engineering, requires ticular genotypes in breeding programs to macronutrients As has study will analyze the wheat genotypes for a source of minerals and variability in wheat been mention earlier there are several several of important minerals, including mineral composition has been reported in encouraging examples of screening studies micro- and macronutrients whereas most several papers.[1,2] A study reported that there on wheat genotypes that demonstrate previous studies tend to focus on only one
