Riviera is back. It produces large, uniform pale yellow tubers suitable for baking and boiling. It is waxy enough for salad use and was liked by the enthusiasts who tried it when it was first introduced. Resistant to virus, common scab and yellow eelworm. Early enough to dodge most blight periods. Now that basic seed grades of Concorde and Accent are not being grown in the UK I think this is an ideal replacement.
