The aim of this work was to determine the influence of different storage temperatures and tuber maturity on development of tuber necrosis caused by Potato virus Y(NTN) . Infected tubers of the cultivar Igor of two different maturity groups and non-infected tubers were randomly distributed into 12 storage regimes. Control treatments were stored at constant temperatures of 4, 13 and 24°C. Tubers in the other nine treatments were stored at 4°C at the beginning of experiment and transferred to 24°C after 1 to 29 weeks after harvest. High storage temperatures enhanced the development of tuber necrosis. Prolongation of low temperature storage delayed the development of necrosis and reduced the number of tubers with necrosis. When tubers were stored at low temperature for 21 weeks or more, no necrosis developed after transfer to high temperature. We could not confirm the effect of maturity on development of necrosis caused by PVY(NTN).
