Bread wheat landraces are important resources for micronutritent improvement in plant breeding programs. This research aims to evaluate 9 macro and micronutrient contents (Fe, Zn, B, K, Mn, Cu, Mg, Ca, Mo) of 37 bread wheat pure lines derived from landraces of West Anatolia (Eskişehir and Kütahya) and Thrace (Edirne and Kırklareli) regions and compare with 11 bread wheat cultivars by using GGE Biplot. Field trials are conducted by incomplete block design with two replications in 2011-2012 growing season in Dardanos Agricultural Facility of Çanakkale Onsekiz Mart University. According to the biplot graphics, iron and zinc contents of genotypes were involved into the same section when boron and molibden contents were also highly correlated. Pure line L4 (TR57999/5) were the most prominent genotype for iron and zinc contents when L36 (TR38316/2) were superior by both boron and molibden contents. Copper contents of grains were found negatively correlated with iron and zinc contents. Results indicate notable variability among pure lines and lesser variability for cultivars for all micronutrients. Wheat cultivars had relatively higher Mo content while could be improved by their Fe, Zn, B, K and Ca contents. Possible candidates are introduced to be used in a future study.
