| The objective of this work was to identify new sources of simple and multiple resistances to Cowpea severe mosaic virus (CPSMV), Cowpea aphid-borne mosaic virus (CABMV) and Cucumber mosaic virus (CMV) isolates in cowpea (Vigna unguiculata). Thirty-three genotypes from the germplasm bank of Universidade Federal do Ceará were tested as to their resistance to four CPSMV isolates, two CABMV isolates and one CMV isolate. Twenty-five days after the first virus inoculations, all inoculated plants, including the asymptomatic ones, were tested by serology. Genotypes were classified as: immune, plants without symptoms and negative serology; resistant, plants with mild mosaic and positive serology; susceptible, plants with mosaic and positive serology; and highly... |

| Durante las temporadas de 2001-2002 y 2002-2003 se realizó una prospección de virus en pimientos (Capsicum annuum L.) en diversas localidades de la Región de Coquimbo (29,5-32° lat. Sur). La determinación de virus se realizó mediante la prueba DAS- ELISA. La importancia relativa de los virus encontrados para ambas temporadas fueron: Virus del mosaico del pepino (CMV) 23,3%; Virus del bronceado del tomate (TSWV) 20,8%; Virus del mosaico de la alfalfa (AMV) 14,8%;Virus Y de la papa (PVY) 14,5% e Impatients necrotic spot virus (INSV) 3,1% (primera identificación de este virus en pimiento en Chile); Virus del mosaico del tomate (ToMV) 2,2% y Virus del mosaico del tabaco (TMV) 4,9%. Los resultados indicaron que al menos el 30% de las muestras estaba infectada... |
