|a The recombinant strain of potato virus Y (PVY), PVYNTN, is the main cause of the potato tuber necrotic ringspot disease (PTNRD) in susceptible potato cultivars, which reduces the quality of potato tubers, in addition to the yield loss. Control of PVY has been the main challenge in most potato-producing areas. Here, the effects of the age-related resistance (ARR) were investigated in transplants of a potato cultivar Yukon Gold to the infection with PVYNTN strain in greenhouse experiments. Within the first 3 weeks after transplanting into soil (week 1 [W1] to W3), Yukon Gold plants developed ARR that impaired the systemic movement of PVYNTN into upper noninoculated leaves and concomitant translocation into progeny tubers starting from W4 after transplanting. The yield and quality of tubers from PVY-infected plants with the established ARR (W5 to W8) were comparable with the healthy controls, suggesting that late PVY infection would not significantly affect commercial potato production. Plants inoculated early (W1 to W2), before the establishment of the ARR, exhibited a 100% primary systemic infection with PVYNTN and produced fewer tubers of smaller sizes, exhibiting PTNRD; this resulted ≤70% yield reduction compared with plants inoculated later in the season (W5 to W8). This ARR greatly restricted the systemic movement of PVYNTN in the foliage and resulted in very limited translocation rates of the virus into tested progeny tubers: 7.8 and 4.1% in 2017 and 2018, respectively, of all plants inoculated later in the season (W5 to W8). This study suggests that PVYNTN management programs in Yukon Gold seed potato should focus more on the early stages of the potato development before the onset of the ARR
