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.
