Grain protein content and gluten strength are major targets in durum wheat breeding programs (Triticum turgidum L. var. durum). Six experiments were conducted in the south of the province of Buenos Aires (Argentina) using a world-wide durum wheat germplasm collection (170 entries) in order to analyzed grain protein content, thousand kernel weight and gluten strength. This collection was genotyped with the Breeders´ 35K Axiom® array and four major genes markers. The population structure was assessed by using a subset of 1,000 SNPs in low linkage disequilibrium and association mapping (AM) was performed using 3,745 markers for all the phenotypic traits
