RESUMO
Seventy-two bean cultivars were tested to determine the presence of the dominant «I» gene for systemic necrosis, which determines death of plants affected by necrotic strain of BCMV (Bean Common Mosaic Virus), before systemic chronic infection begins. Plants that show this hypersensitivity reaction neither show mosaic symptoms nor allow the transmission of the virus to the seed. In order to discriminate the bearer materials of the gene "I" the primary leaves of bean plants were inoculated eight days after sowing with a mix of virus strains NL3 and NL4. The reactions evaluated seven days after the inoculation indicated that 65 of these genotypes have the dominant gene of systemic necrosis that confers the dominant type resistance.
