Potato virus Y (PVY) the type member of the genus Potyvirus, occurs wodd-wide as isolates which differ in host range and the type of symptoms caused. The sequences of a 5' segment of viral RNA overlapping the 5' non-translated region (5'NTR) alone (ten isolates) or the 5'NTR and the adjacent P1 coding region (eight isolates) were established. These data were used to quantify the polymorphism in the Y-terminal part of the PVY genome. Nucleotide sequence identity between isolates ranged from 66-100 % in the 5'NTR and from 70-100% in the P1 coding region. The lowest amino acid sequence similarity between PVY P1 was 77%, illustrating the high variability of this protein in the PVY species. Phylogenetic trees based on either 5'NTR or P1

The Ry-fsto gene from Solanum stoloniferum for extreme resistant to Potato virus Y maps to potato chromosome XII and is diagnosed by PCR marker GP122718 in PVY resistant potato cultivars

A novel locus for extreme resistance to Potato virus Y (PVY), Ry-f sto , was identified on potato chromosome XII. The gene Ry-f sto has been introgressed from the wild potato species Solanum stoloniferum. Inheritance of Ry-f sto in the tetraploid potato population Rysto was consistent with the model of a single, dominant gene. Bulked segregant analysis identified an ISSR (inter-simple sequence repeat) marker UBC 857 980 linked to Ry-f sto . This marker mapped to linkage group XII of a reference potato RFLP (restriction fragment length polymorphism) map. Chromosome XII specific RFLP markers were converted into PCRbased STS and CAPS markers and tested for linkage with Ry-f sto in the population Rysto. CAPS marker GP122 718 was tightly linked to the resistance gene and was successfully used to identify Polish and German cultivars expressing extreme resistance to PVY. This indicates that the source of Ry-f sto has been widely utilized in various potato breeding programs and can be monitored by a diagnostic marker in markerassisted selection.

“…Firstly, an important fact to consider is that PVY is the most dominant potato virus in Europe (Chrzanowska, 1991;Horvath and Wolf, 1999;Chrzanowska and Doroszewska, 2004;Chatzivassiliou et al, 2008;Kotzampigikis et al, 2008), as well as in Serbia (Buturović and Kus, 1989;Milošević, 1992a).…”

PVY has been reported to cause the severest damage in seed potato production worldwide (Verbek et al, 2010), and is more harmful than PLRV in Europe and Serbia (de Bokx and Piron, 1990;Chrzanowska, 1991;Horvath and Wolf, 1999;Milošević, 1992 and2009;Milošević and Petrović, 2000).…”

SUMMARYAphids are the most important vectors of potato viruses during the crop's growing season. The most widespread and damaging viruses, the potato virus Y and potato leaf roll virus, are transmitted by aphids in non-persistent and persistent manner, respectively. The two viruses cause the greatest concern of potato producers and a great constraint to seed potato production in Serbia, the region and across the world. Potato virus Y is particularly harmful, given its distribution and spreading rate.Seed potato production systems under well-managed conditions involve a series of virus control measures, including the monitoring of outbreaks of winged aphids, their abundance and species composition, in order to forecast virosis, i.e. potential plant and tuber infection periods. Monitoring the aphid vectors of potato viruses enables determination of optimum dates for haulm destruction when higher than normal numbers of winged aphids as vectors of economically harmful diseases have been observed. Haulm destruction in a potato crop reduces the risk of plant infection and virus translocation from the aboveground parts to tubers, thus keeping the proportion of infected tubers within tolerance limits allowed for certain categories of seed potatoes. This practice has positive effects if used in combination with other viral disease control measures; otherwise, it becomes ineffective.This paper provides an integral analysis of the effects and role of monitoring outbreaks of aphids, their abundance and species composition in timing haulm growth termination to prevent plant infection, virus translocation and tuber infestation in potato crops in Serbia and the wider region.
