Abstract: Powdery mildew incited by Oidium erysiphoides f. sp. ziziphi, Yan and Wang is the most important disease that causes maximum reduction in yield and quality of ber (Ziziphus mauritiana Lamk.) fruits grown under semi-arid and arid regions of India. Developing a varietal resistance to disease provides an early, cheaper, stable and effective means of disease control. In the present investigation, 21cultivars / germplasm were tested for resistant against Oidium erysiphoides f. sp. ziziphi. Out of theses, two cultivars / germplasm namely Darakhi-2, Nazuk showed 2.60 and 4.67 per cent disease intensity, respectively and categorized as resistant whereas Faliso Alwari, Jogia, Kaithali, Katha, Kishmis, Mehroon, Mundia, Safarchandi, Tabestaso and ZG-3 showed moderately susceptible reaction and Chhuhara, Chhuhara-1, Chonchal, Gola, Illaichi, Kathaphal, Seb, Thornless and Umran showed susceptible reaction.
