Developing cultivars with high grain yield and optimal quality traits for pasta production is the main goal of durum wheat breeding programs worldwide. This work summarize the main results of our research group using a RIL mapping population (UC1113 x Kofa) evaluated in six environments from Argentina to detect QTLs and linked markers for yield and yield components, phenology, gluten strength, protein and color. QTLs affecting yield and yield components were mapped on chromosomes 3BS (gwm493), 2BS (cfa2201), 3AL (ksm28-wmc428) and 4AL. The first two QTL also affect heading date and/or flowering time. QTLs affecting flour yellow color (Fb*) were located on 4AL (wmc219), 6AL (wmc553) and 7BL (cfa2040-barc1073).
