Conteúdo: 	A scab disease caused to Elsinoe fawcettii, is a desease who is present in all citrus areas in Brazil, which significantly undermines the quality of fruit  for trade in natura. Under conditions of natural infection, in Bebedouro, São Paulo, Brazil, researched behavior of tangerines and hybrids to E. fawcetti. For each genotype, three plants whose are 12 years old, in maturation fase of fruits, between April and May of 2008, were rated 100 fruits distributed in the four quarters of each plant. Fruits were evaluated using note scale between 0 (no symptoms) and 6 (several symptoms). No symptoms in fruits were observed in genotypes: 3 Clementis (C. elementina Hort. ex Tan.); 5 Mandarins (C. reticulata Blanco), (C. deliciosa Ten.), (C. tangerina Hort. ex Tan.), (C. nobilis Lour.); 1 Mandarin (hybrid) (C. nobilis x C. deliciosa) and 1 Satsuma (hybrid) (C. unshiu Marc. x C. deliciosa Ten.) while 1 Clementin (C. clementina Hort. ex Tan.); 2 Mandarins (C. reticulata Blanco); 1 Satsuma (C. unshiu Marc.); 1 Tangelo (C. tangerina x C. paradisi Macf.); 1 Mandarin (hybrid) (C. clementina x C. reticulata); 2 Tangor (hybrids) (C. temple Hort. ex. Y. Tan. x C. tangerina Hort. ex. Tan.), (C. clementina Hort. ex Tan. x C. sinensis (L.) Osb.); 4 Satsuma (hybrids) (C. unshiu Marc. x (C. reticulata Bla. x C. sinensis Osb.)) and (C. unshiu Marc. x C. deliciosa Ten.) showed itself as moderate resistance, with severity ranging from 1 to 3.
