Summary
The sugarcane mosaic virus is a pathogen that causes severe disease to sugarcane. New varieties resistant to insects and pathogens have been developed in the last 70 yr through sugarcane breeding programs, but this takes between 10 and 15 yr. Tissue culture techniques are used as an aid for sugarcane improvement to increase desirable agronomic characteristics, such as disease resistance. In the present work, we report the generation of somaclonal variants from sugarcane (Saccharum spp.) cultivar PR62258 susceptible to Sugarcane Mosaic Virus, by somatic embryogenesis. These new variants identified as AT626 and BT627 are resistant to Sugarcanes Mosaic Virus strains A and B, respectively. We established an indirect enzyme linked inmunosorbent assay (ELISA) to test the presence of the viral particles in plants, and its was demonstrated that the leaves of resistant somaclones do not contain viral particles. The field performance of the somaclones AT626 and BT627 was similar to the field performance of the mother plant PR62258.
