A total of 292 accessions of pea (Pisum spp.) were screened under field conditions for resistance to powdery mildew (Erysiphe polygoni) and rust (Uromyces fabae). Five entries—P431, P436, Gloire de Quimper, Sel. 18, and Sel. 30—one wild type (PJ207508), and the species Pisum asiaticum were resistant to powdery mildew. Three accessions—PJ207508, PJ222117, and EC109188—were resistant to rust. PJ207508 was resistant to both diseases.
