Three components of partial or slow-rusting resistance, i.e. latent period, infection frequency and pustule size were measured in both see­dling and adult stages for ten wheat cultivars including seven long-spike cvs. The slow-rusting cultivars had less infection frequency, longer latent period, smaller puitule size and less Area Under Disease Progress Curve (AUDPC). Accordingly, the ten cultivars can be classified into three groups i.e. fastrusting, moderate-rusting and slow-rusting and slow-rusting. Based on the obtained data, some wheat cultivars showed dif­ferent behaviour at seedling and adult stages, while others showed the same behaviour at both stages. Slow-rusting cultivars at both stages were Sidsl , Sids2 and Sids3. These cultivars can be included in the breeding' program.
