Résumé

In storage trials, more symptoms developed in potato tubers kept at 9 than at 4 deg C, irrespective of the cultivar. Cutting the tubers enhanced post storage symptom development in some cultivars. Of 14 cultivars grown in Sweden, those used for crisp products were more inclined to develop spraing than the others. A comparison in Sweden, Denmark and Finland indicated substantial geographic variation suggesting variation among isolates on the virus. From glasshouse experiments it was found that inoculations carried out at flower bud development or at flowering resulted in most spraing. Cultivar trials in pots produced a low level of spraing symptoms in general.
