Thirty-three durum wheat cultivars were grown during 2009–10 in a field with CSBMV at Cadriano, near Bologna, and evaluated for resistance on the basis of symptom severity, DAS-ELISA value, and agronomic performance. The cultivars were grown in 10-m2 solid-seeded plots distributed in the field according to a randomized block design with three replicates. Symptom severity was evaluated on three dates using a 0–4 scale. DAS-ELISA was performed on extracts from a bulk of the basal half of the second and third youngest leaves of 10 randomly chosen plants/plot collected on two dates. The cultivars Dylan and Biensur showed very mild symptoms and relatively low ELISA values; both produced high grain yields, superseeded only by those recorded for the moderately resistant cultivar Levante. Relatively low symptom scores and ELISA values, as well as relatively high grain yields, were recorded also for cultivars Duilio, Saragolla, Alemanno, Pharaon, Meridiano, and Svevo. Mean ELISA value and mean symptom severity score were significantly correlated (0.736**), and both resistance parameters were significantly correlated with all the agronomic traits considered except test weight. Regression analysis indicated that cultivars showing symptom scores between 3.0 and 3.8.
