PENA, Z  y  TRUJILLO, G. Identification of seed borne viruses in growing areas of beans (Phaseolus vulgaris L.) and cowpea (Vigna unguiculata (L.) Walpers) in Venezuela. Rev. Fac. Agron. [online]. 2007, vol.24, n.1, pp.1-21. ISSN 0378-7818.

With the purpose of knowing the incidence of seed borne viruses in production areas of beans and cowpea, 53 materials used as seed were evaluated. Viral isolations coming from seeds sowed in shelter protected against insects; being identified the beans isolations like: "Colombian 1", "Colombian 2" and "Tucutunemo"; and those of cowpea like "Black Eye", were selected. Material was multiplied, stability test in sap were carried out, vector transmission was studied, the hosts range was determined, serological tests with the available antibody were carried out. In three viral isolations of beans, the bean southern mosaic virus (BSMV) was identified in a sample of Tucutunemo Valley, Aragua state. In the material coming from Colombia collected in Sanare, Lara state, it was detected simple viral infection BSMV and double infection BSMV and bean common mosaic virus (BCMV). In cowpea, it was identified the cowpea severe mosaic virus (CpSMV) from seed of Portuguese and Falcon states. Through this essay was corroborated the necessity of establishing a phytopathological control, for the exclusion of national or imported seed materials not suitable for sows, and also the importance of seed certification.
