Abstract:<\/strong><\/span><\/p>\n

The aim of this study is to determine the percentage of loss in yield of some durum wheat varieties against wheat leaf rust, and to identify whether the slow rusting has a positive effect in limiting yield loss. The study was carried out in the fields of experiments at Faculty of Agriculture, Aleppo University, Aleppo, Syria, 2015, included six durum wheat varieties (Cham1, Cham5, Douma1, Cham9, Beltagy and Massine), according split plot design, the first treatment of the main factor was infected by virulent races of p. trichina<\/em>, where the second treatment was treated by the systematic fungicide (Bayfidan 250). Average coefficient of infection, area under the disease progress curve, average weight of a thousand grains, average productivity and the percentage of loss in both plots were calculated. Results were statistically analyzed according to Duncan distribution. The results showed a difference in the reaction of the studied cultivars against the pathogen in the seedling stage and the mature plant. The highest severity was in Doma 1 (90S), while Cham 9 and Beltagy were resistant. P.triticina<\/em> reduced the WTG, and the highest reduction rate was 19% in Doma 1, and the loss of production was 30%, 7% in Douma 1, and Massine, respectively. \u00a0No losses in the two resistant varieties (Cham 9 and Beltagy), they considered as the vertical resistance model that prevent damage of wheat leaf rust. The most important result is that Massine as the model of slow rusting reduced productivity in order to become more productive than the susceptible productive variety (Doma 1), and can be used in epidemic zone in rust.<\/span><\/p>\n
