Abstract

Resistance of transformed and non-transformed spring oilseed rape cv. HM-81 to the infection with cauliflower mosaic virus (CaMV), turnip yellow mosaic virus (TYMV) and turnip mosaic virus (TuMV) was studied, to determine the influence of transformation on susceptibility of plants to viruses. For experiments the non-segregating R 1 generation of primary transformant HM-81-JZ and control plants of cv. HM-81 were used. The primary transformant was obtained by inoculation of stems withAgrobacterium rhizogenes 15834. All transformed plants of R 1 generation had typically "transformed" phenotype. No significant differences were revealed in the resistance of both transformed and non-transformed plants to each virus, as proved by qualitative and quantitative ELISA and visual evaluation of symptoms. Transformed plants infected with turnip yellow mosaic virus showed significantly lower reduction of green mass yield than non-transformed. In the case of CaMV and TuMV infection reduction of yield of transformed and non-transformed plants was almost the same.
