Developing cultivars with high grain yield and optimal quality traits for pasta production has been the main goal of durum wheat breeding programs worldwide. The present work resumed the main results of our research group working with a bi-parental mapping population growing in different locations of the main durum wheat area of Argentina. The identification of QTL and linked markers for grain yield and yield components, phenology, gluten strength, protein and color was performed using a population of 93 RILs (UC1113 x Kofa) evaluated in six different environments from the Province of Buenos Aires. Pleiotropic regions were identified affecting two or more traits.
