Summary: Durum wheat cultivars derived from CIMMYT germplasm are widely grown in West Asia, North Africa and the Mediterranean region. Septoria tritici leaf blotch is a major disease on durum wheat in those areas. To study the inheritance of resistance, parents and crosses of Altar 84 and Sula (resistant) with Bejaga Red (susceptible) were inoculated in the field with a virulent isolate of Septoria tritici (Mycosphaerella graminicola). Preliminary results from F2 and F3 generations indicated that resistance in both Altar 84 and Sula is controlled by two recessive genes. The use of this source of resistance in breeding is recommended.|Los cultivares de trigo duro derivados del germoplasma de CIMMYT son cultivados ampliamente en el este de Asia, norte de Africa y la region del Mediterraneo.
