Abstract	In the past decade, the incidence and distribution of the recombinant, tuber necrotic strain of Potato virus Y (PVYNTN) has been increasing in the US seed potato crop while the ordinary strain (PVYO) has been decreasing. The transmission efficiency of both strains was determined from two potato cultivars when acquired sequentially by the same aphid or when acquired by separate aphids and inoculated to the same plant. PVYNTN was transmitted more efficiently than PVYO and the order of acquisition or inoculation did not affect the preferential transmission of PVYNTN. When a recipient plant became infected with both strains, PVYNTN maintained higher titre than PVYO and would facilitate the acquisition of PVYNTN. Furthermore, the acquisition and transmission of PVYNTN over PVYO was enhanced in the potato cultivar that expressed a strain-specific Ny-like resistance gene that confers partial resistance to PVYO.
