Strain-specific hypersensitive (HR) and extreme resistance (ER) phenotypes elicited in potato plants by three Potato virus Y (PVY) isolates in strain groups PVYO (BL and DEL3) and PVYD (KIP1) were studied. PVYO and PVYD isolates elicit HR genes Ny or putative Nd, respectively, and all three isolates elicit ER gene Ry. They were inoculated to 39 Australasian, European, or North American potato cultivars released over a 117-year period and harvested tubers were replanted. Both primary and secondary symptoms were recorded. Two European cultivars always developed ER following sap and graft inoculation and, thus, carried comprehensive PVY resistance gene Ry. One Australasian and two European cultivars always developed susceptible phenotypes and, thus, lacked genes Ry, Ny, and putative Nd. Sap inoculation with isolate KIP1 elicited localized HR (LHR) in 31 cultivars and both LHR and systemic HR (SHR) in three others; thus, all carried putative Nd. Isolates BL and DEL3 both elicited susceptible phenotypes in 11 of these 34 cultivars but LHR alone, SHR alone, or both LHR and SHR in the other 23 which, therefore, all carry Ny. With these two isolates, SHR expression ranged from very severe to very weak, with the greatest numbers of isolate–cultivar combinations occurring in the severe category with BL (n = 11) and moderate category (n = 12) with DEL3. Within the same isolate–cultivar combination, overall, SHR symptom expression was weaker with secondary than primary infection. With both primary and secondary infection, SHR expression was most severe with KIP1 and weakest with DEL3. Genes Ny and putative Nd were present in cultivars released between 1939 and 2010 or 1893 and 2010, respectively, occurring in cultivars from all three world regions. These findings have important implications concerning breeding new PVY-resistant potato cultivars, especially for countries lacking healthy seed potato stocks, or where subsistence farmers cannot afford them. An alternative to including gene Ry is incorporating as many strain-specific PVY resistance genes as possible.

Necrotic Symptoms

Six potato virus Y isolates from Victoria and Queensland were characterized on the basis of host plant reactions. Four isolates from potato produced symptoms in indicator plants and potato cultivars consistent with those caused by the PVYO group. Two isolates from tobacco produced necrotic symptoms on some tobacco cultivars characteristic of the PVYN group, but did not systemically infect potato cultivars and therefore could not be considered to belong to any of the previously described PVY strain groups. Despite the wide variation in their biological characteristics, an antiserum produced to one of the potato isolates was able to detect all six of the isolates when used in ELISA

The Occurrence of Major Potato Viruses in PolandThe research was carried out in field conditions in Bonin in the north of Poland, in 1996-2009, and additionally in Bonin, Przechlewo (also in the north of Poland) and Stare Olesno located in the southern part of Poland, in 2008 and 2009. The outcome showed thatPotato virus Yposed the most serious threat to potatoes. The share of progeny tubers infected by this pathogen was 32.5% (mean of 1996-2009) and was considerably higher in comparison to PVM (18.2%) and PVS (22.1%), and in particular to PLRV (15.3%). The additional research carried out in the years 2008 and 2009 in three places: Bonin, Przechlewo (located in the north of Poland) and Stare Olesno (south of Poland) included three potato cultivars of low resistance to PLRV. The results also showed a very low pressure of this virus in both years and in all places of the research. In Przechlewo, PLRV was not detected at all in progeny tubers. While in Stare Olesno and particularly in Bonin, the percentage of PLRV-infected tubers was very small. The average for years and the average for localities amounted to 2.1 and 0.3%, respectively. Whereas the share of tubers infected by PVY, PVM and PVS was considerably higher and ranged from 11.8% to 59.8% depending on the cultivar, year and place. The progeny tubers infected by PVY and PVM were mostly detected in the very early term of exposure(from the 21st of May to the 1st of June). Whereas PVS posed the most serious threat in a somewhat later term i.e. during the exposure of plants which lasted from the 1st of June to 11th of June.
