Introduced durum wheat (Triticum turgidum L. subsp. durum) genotypes were evaluated for grain yield and related characters at Hudeiba, northern Sudan. Grain yield of the tested genotypes ranged from 0.7 to 4 t per ha, with many genotypes showing 6-30 percent better yields than the check (1.7-2.9 t per ha). Heading of the genotypes was within 45-80 days, while maturity was within 81-113 days, depending on season. The genotypes with medium maturity gave better grain yield than the early and late genotypes. Tillering capacity of the genotypes varied greatly (260-590 spikes per m2), but there was less variation among the genotypes in plant height (58-91 cm). Seeds per spike and 1000-kernel weight ranges were 24-43 and 32-56 g, respectively, with many genotypes with larger seed weight than the check (36-41g). Thus, selection of durum-wheat genotypes with medium maturity, high tillering capacity and large number of seeds/spike, besides seed yield itself, could be effective under northern Sudan conditions
