Thirty citrus varieties/cultivars were assessed for resistant and susceptible source against the canker disease caused by Xanthomonas axonopodis pv. citri in a field trial conducted in the research area, Department of Plant Pathology, UAF during the 2017-19 years under Randomized Complete Block Design (RCBD) . Eleven varieties i.e.Citrus japonica (Kumquat), Citrus pseudolimon (GALGAL), Citrus sinensis cv. Jaffa, Citrus reticulata cv. mungal singh, Citrus reticulata cv. tangerine, Citrus sinensis cv. pine apple, Citrus poncirus (Trifoliate orange), Citrus grandis (Pomelo), Citrus aurantium (Bitter Orange), Citrus medica (Citron), Citrus sinensis cv. Washington navel expressed (1.20-3.80 %) resistant response. Four genotypes namely Citrus aurantifolia swingle (Kagzi lime), Citrus aurantifolia (Key lime), Citrus latifolia (Persian lime), Citrus sinensis cv. ruby red exhibited (7.60-8.00 %) moderately resistant response while one variety Citrus limonia cv. mayer lemon showed (12.90 %) moderately susceptible response. Four varieties named as Citrus reticulata cv. feutral's early, Citrus limettioides (Sweet lime), Citrus sinensis cv. succari, Citrus sinensis cv. valentia late showed (19.00-20.70 %) susceptible response. Ten varieties namely Citrus sinensis cv. red blood, Citrus reticulata cv. malta, Citrus limonia, Citrus paradisi, Citrus reticulata cv. kinnow, Citrus sinensis, Citrus jambhiri (Rough lemon), Citrus paradisi cv. shamber, Citrus paradisi cv. duncan, Citrus paradisi cv. foster expressed (26.60-28.70 %) highly susceptible response against citrus canker. No citrus cultivar was found immune.
