The stability of yield performance is one of the most desirable characters of a genotype to be released as a variety, which allows the developed varieties to be adopted in large areas. To obtain high yielding and stable durum wheat genotypes, 18 durum wheat lines and promising lines along with two commercial durum (Behrang) and bread wheat (Chamran) check cultivars were evaluated in four warm and dry locations of Iran including Darab, Ahvaz, Khoramabad and Dezful  during two cropping seasons (2013-2015). The experiments were conducted in form of RCBD with three replications. Seed yield and some agronomic characteristics were recorded in each location. Results of SIIG criterion, calculated based on all parametric methods, indicated that lines DW-93-10, DW-93-7, DW-93-15,
DW-93-16, DW-93-4 and DW-93-18, in comparison with the other lines, had the least deviation from the ideal genotype (d+) and had the greatest deviation from the non-ideal (d-) one; therefore these lines with maximum SIIG were the stable lines. Results of SIIG index, calculated based on all non-parametric methods, indicated that the lines DW-93-18, DW-93-15, DW-93-10, DW-93-16, DW-93-7, DW-93-14, DW-93-2, DW-93-4 and DW-93-5 were characterized with maximum SIIG and were introduced as stable genotypes. Based on parametric and non-parametric procedures, the lines DW-93-10, DW-93-7, DW-93-15, DW-93-4 and DW-93-18 were introduced as stable genotypes. Finally, by using average of yield, grain quality indices and resistance to diseases, lines DW-93-4 and DW-93-5 along with DW-93-19 as the earliest maturity lines were selected to be tested in on-farm yield trials of next cropping seasons.
