Abstract - The evaluation of the adult plant resistance of 28 genotypes belonging to Triticum L and Aegilops L to Pseudomonas syringae pathovar atrofaciens (PSA) were carried out at stage 10.1 (Large, 1954) after inoculation by the method of Vassilev and Karov (1986) in a glasshouse. The investigated genera showed a partial adult plant resistance to PSA. The proportion of genotypes susceptible to PSA at the highest concentration was larger for Triticum than for Aegilops.

Résumé - Étude de la résistance du blé et d'Aegilops à Pseudomonas syringae pv atrofaciens au stade adulte. La résistance à Pseudomonas syringae pv atrofaciens des plantes adultes de 28 génotypes de Triticum L et d'Aegilops L (au stade 10.1 Large 1954) a été étudiée après inoculation en serre (Vassilev et Karov, 1986). Les genres étudiés montrent une résistance partielle à PSA au stade adulte. La proportion de génotypes sensibles au PSA utilisé à la plus haute concentration étaient plus élevée pour Triticum que pour Aegilops.
