Abstract
Potato cultivar Igor is very susceptible to the potato virus YNTN, when plants are grown in soil. The symptoms of the potato tuber ring necrotic disease (PTRND) caused by PVYNTN are severely expressed (clear mosaic and brightening on the leaves, severe necrosis on the stems and veins, accelerated leaf senescence and leaf drop; Le Romancer et al. 1994). However, systemically PVYNTN-infected plants transferred to stem-node culture exhibit an enhanced tolerance to PVYNTN (Dermastia and Ravnikar, 1996). Subsequent studies on different potato cultivars revealed that susceptibility to PVYNTN was cultivar dependent (Jerman et al., 1996). Moreover, the susceptibility in soil correlated with tolerance in tissue culture and vice versa. Thus, the symptoms of PVYNTN-infection were the most prominent in in vitro grown plants of cv. Pentland Squire (Jerman et al., 1996), which is known as tolerant cultivar to PVYNTN when grown in soil.
