Resumen:
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) to detect QTLs and linked markers for yield and yield components, phenology, gluten strength, protein and color evaluated in environments from the Province of Buenos Aires, Argentina. QTLs affecting yield and yield components were mapped on chromosomes 3BS(gwm493), on 2BS(cfa2201), on 3AL(ksm28-wmc428) and on 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). The QTLs on 6AL and 7BL plus a 7BS QTL(barc72) also affect yellow pigment content (Ypc). Another important QTL for Ypc and Fb* was linked to Psy-B1 gene.
