Historical shifts in the seed mineral micronutrient concentration of US hard red winter wheat germplasm - The yield of wheat has greatly improved through breeding, but it is not known how this has affected seed micronutrient content. In the present study, the iron (Fe), zinc (Zn), copper (Cu), and selenium (Se) content of seed of 14 US hard red winter wheat varieties from production eras spanning more than a century was measured.
Breeding for micronutrients in staple food crops from a human nutrition perspective - Over three billion people are currently micronutrient malnourished. This report discusses how breeding has effected staple food crop nutrient content.
Grain composition and amino acid content in maize cultivars representing 80 years of commercial maize varieties - In order to determine how modern hybrids have impacted grain composition and amino acid content of the corn crop, a set of cultivars were characterized that were widely grown in different eras from the 1920s through 2001.
