Abstract: Durum wheat (2n=28, AABB, Triticum turgidium L. ssp. Durum) is the most commonly cultivated form of allotetraploid wheat and is grown on 8% of the world’s wheat area. The trial was conducted at Dabat Station of Gondar Agricultural Research Center, northern Ethiopia, with the objective of screening and advancing the best-performed landraces with respect to disease and other quantitative parameters. One hundred durum wheat landraces were evaluated using a 10*10 simple lattice design. The analysis of variance revealed the presence of highly significant (p<0.01) variation among the landraces for all traits. The highest and the lowest plant height was recorded from genotype 206421 (143cm) and Mangudo (82.45cm), respectively. The highest number of kernels per spike was obtained from Workaye (51.75) while the lowest was from 8019 (19.90). Genotype 236986 and 229251B had the highest and the lowest thousand kernels weight of (44.24) and (10.8 gm). The highest grain yield was recorded from 219368 (7.27t/ha) while the lowest was obtained from 206421 (0.64t/ha). The observed wide range of differences among the genotypes for these main traits may be due to genetic differences. According to this result, none of the landraces were immune and highly susceptible to septoria tritici blotch, the majority was moderately resistant (68) to moderately susceptible (30), while only the two landraces resistance to septoria. According to the result, 61 genotypes were found immune against stripe rust. 14 genotypes showed the symptom of resistance, while 13 lines in the range of resistance to moderate resistance. Only 4% of the observed landraces were moderately susceptible and 8% observed to be highly susceptible to stripe rust. These results indicated that a large number of genotypes have a high level of resistance against wheat stripe rust and create more genetic variations through the crossing.
