Abstract
Rutabaga (Brassica napus L. Group Napobrassica) cultivars were screened for resistance to turnip mosaic virus (TuMV), and the inheritance of resistance was studied. Immunity and resistance were found in four of 49 rutabaga cultivars evaluated. The cultivar ‘Sensation’ was immune to the Ontario strain of TuMV. In crosses between susceptible ‘Laurentian’ and resistant Line 165 and susceptible triazine-resistant ‘Laurentian’ and Line 165, TuMV resistance was determined by a single dominant gene.
