‘Tina’ is the only cultivar of swede (Brassica napus L. var. napobrassica) resistant to both dry rot (Leptosphaeria maculans (Desm.) Ces. et de Not.; conidial state: Phoma lingam (Tode ex Fr.)) and clubroot (Plasmodiophora brassicae Wor.). Tina is also moderately resistant to cauliflower mosaic virus, turnip mosaic virus, and the cabbage aphid (Brevicoryne brassicae (L.), biotype NZ-1, but not biotype NZ-2). Five cultivars of swede and one cultivar of turnip (Brassica campestris L.) have contributed to the breeding of Tina. |
