Alternaria brown spot is caused to A. alternata and is one of the most important problems to production in susceptible citrus species. Resistance cultivars are essential for a sustainable mandarin cultivation. The reaction of 22 tangerines and its hybrids to A. alternata were studied in February 2008 in field trees in Bebedouro, São Paulo, Brazil. Initially, 25 fruits measuring 30-40 mm and 100 young leaves (6 to 12 days) by plant, were inoculated by a patogenic isolate in conidial concentration ajusted to 104 conidiamL-1. After inoculation, fruits and leaves were protected in paper bags semi-kraft, previously sprayed to steril water, for 12 hours. Fruits and leaves were evaluated using note scale between 0 (no symptoms) and 3 (several symptoms). Were observed resistance to A. alternata infection in: 4 Clementines: (C. clementina Hort. ex Tan.); 6 Mandarins: 2 (C. reticulata Blanco), 2 (C. tangerina Hort. ex Tan.), 1 (C. deliciosa Tan.) and 1 (C. nobilis Lour); 1 Tangelo: (C. tangerina x C. paradisi Macf.); 2 Mandarins (hybrids): 1 (C. nobilis x C. deliciosa) and 1 (C. clementina x C. reticulata); 1 Tangor (hybrid): (C. clementina Hort. ex Tan. x C. sinensis (L.) Osb.); and 2 Satsumas (hybrids): (C. unshiu Marc. x C. deliciosa Tan.). |
