Résumé:
In the Northeastern part of Brazil, the mosaics caused by viruses, emerge as the most important
diseases for the cowpea, thus becoming a limiting factor of production. Genetic resistance has been considered
as the best alternative of controlling
. Thus, the aim was to evaluate the F3 popula
tion behavior developed for the resistance against different isolated CPSMV collected from different areas of
cultivation. Leaf samples presenting cowpea mosaic symptoms were collected from plantations from the states
of Pernambuco and Paraiba. There was inoculation on susceptible cultivars of cowpea kept in house vegetation.
The isolates were also diagnosed by reactions RT PCR using specific primers. Of the 185 F3 plants inoculated
183 plants were resistant to different isolates of CPSMV.
