Objective. Monitoring observations over the phytovirological condition of potato planting in different regions of Ukraine, taking into account potato degeneration zones. Methods. Laboratory (virological, immunological, electronic microscopy), field, statistical. Results. The map and diagrams show the results of monitoring studies conducted in 2016–2020, during which 435 varieties of potatoes of Ukrainian and foreign selection were tested. In the zone of the lowest degeneration or the zone with a relatively low degree of infectious load, 100 % spread of pathogenic complexes involving potato virus Y in the Region of Zakarpattia, potato viruses M and Y in the Region of Chernivtsi, ranging from 89 % to 100 %. In the zone of strong degeneration of the culture or the zone with a high degree of infectious load, spread of pathogens of potato viral diseases is from 94 % to 100 %, and the vast majority of viruses belongs to pathogens of severe viral diseases. In the zones of mild and moderate degeneration, which belong to the zones with relatively low degree and with moderate degree of infectious load according to another diagram, potato virus M in monoinfection from 17 % to 50 %, in the pathogenic complex with potato virus S from 8 % to 36 %, with potato virus Y from 6 % to 32 % was detected. In the Region of Kyiv, the spread of potato virus Y+S complex reaches 65 %. In all areas, there is an extremely high level of infection of the culture with potato virus M, which is the cause of severe viral diseases of potatoes. Conclusion. The results of phytovirological monitoring show that the boundaries between potato degeneration zones are smoothed down. Climatic changes, active resettlement of virus vectors, intensification of trade relations with the constant import of foreign potato seed material result in the significant spread of pathogens of potato viral diseases.

The results of monitoring researches of potato virus diseases in the soil and climatic conditions of the Chernigov region. An analysis of the situation in the potato seed shows that the variety is largely defeat viral diseases. In potato seed plots found: potato M-, S-, Y-virus, in monoinfection, and as part of pathocomplexes. Prevails in crops entomophilous potato M virus as monoinfection (36 %) or in combination with other mosaic viruses. Potato virus Y is found in 18 from 47 potato cultivars. A study of the species composition of pathogens and their vectors, infection pathways in the field and deve lopment of viral disease, is the basis for the proper and effective application of safeguard measures.

Resistance To Viruses

Molecular markers within or close to genes of interest play essential roles in marker-assisted selection. PCR-based markers have been developed for numerous traits in different plant species including several genes conferring resistance to viruses in potato. In the present work, rapid and reliable approaches were developed for the simultaneous detection of Ryadg and Ry-fsto, Ns, and PLRV.1 genes conferring resistance to Potato virus Y, Potato virus S and Potato leafroll virus, respectively, on the basis of previously published and newly modified markers. The sequence characterized amplified region (SCAR) markers for Ryadg, Ns and PLRV1 and the newly modified cleaved amplified polymorphic sequences (CAPS) marker for Ry-fsto were amplified in one PCR reaction which could simply characterize Ryadg and PLRV.1 resistance. Additional digestion of amplicons with EcoRV and MfeI for genotyping the Ry-fsto and Ns resistance genes, respectively, was needed. The effectiveness of genotyping in triplex and tetraplex PCRs was tested on 35 potato varieties used for potato seed production and breeding programs.

Certified Potato Seed

Totals of 960 and 286 certified potato seed lots from locations across North America were planted in trials in Washington and Oregon, respectively, in 2001 to 2003 and tested for strains of Potato virus Y (PVY). The incidence of PVYO-infected lots averaged 16.4 and 25.9% in the Washington and Oregon trials, respectively. There was a general trend of increasing incidence of the PVYO, PVYN:O, and PVYN strains during this period, as evidenced by more infected cultivars, sites of seed origin, and number of seed growers providing infected seed lots. In particular, there was a dramatic increase in seed lots with the PVYN:O strain from 2002 to 2003. PVYN:O, in contrast to PVYO, which only causes yield reduction, also causes internal and external damage to tubers, making them unmarketable. In 2003, PVYN:O occurred in seed lots originating in eight states and three Canadian provinces. The increased incidence of PVYN:O was likely due to the difficulty in differentiating this strain from PVYO. The prevalence of PVY in potato seed lots documented herein poses a threat to potato production in the United States and suggests that current measures to reduce the incidence of this virus are inadequate.

Potato virus Y (PVY) is a reemerging problem in potato production in North America. Although the “ordinary” strain, PVYO, is still the dominant isolate in U.S. seed potatoes, the recombinant strain of the virus PVYN-Wi (= PVYN:O) has become widespread. An increase in the prevalence of a PVY strain could be due to differences in the efficiency of transmission by aphid vectors. The transmission efficiency by a clone of Myzus persicae was determined for five isolates each of PVYO and PVYN-Wi. An aphid transmission assay was developed based on the use of potato seedlings from true potato seed, allowing for greater control of plant age and growth stage. No apparent differences in transmission by M. persicae were observed. Single isolates of PVYO and PVYN-Wi were tested for their ability to be transmitted from potato to potato by five aphid species: Aphis glycines, A. gossypii, A. nasturtii, M. persicae, and Rhopalosiphum padi. Both PVY isolates showed a similar transmission phenotype in being transmitted efficiently by M. persicae but very poorly or not at all by A. glycines, A. gossypii, and R. padi. The aphid A. nasturtii transmitted both isolates with an intermediate level of efficiency. The data do not support a model for a differential aphid transmissibility being responsible for the increase in the prevalence of PVYN-Wi.

The examinations of potatoes original seed nursery in north regions of Ukrainian marshy woodlands in 2012 (47 sorts) were performed. It was revealed that spreading of viral infection and diseases symptoms onset on potatoes cultivars increases with the number of field reproductions from 8,1 % (tube plants – seedlings) to 77–100 %. The wide-spreading of latent infections was observed – 57 % of tested samples. Potato virus М prevails in plantings as monoinfection (36,2 %) or in complex with other mosaic viruses (99 %), Potato virus Y was detected in 38,3 % of cultivars, with domination of necrotic isolates. The need of efficient protection and constant viral control of seed material with the use of laboratory methods and modern diagnostic facilities is emphasized.

Cultivated Potatoes

Potato (Solanum tuberosum L.) is the fourth most important food crop in the world. It is the most economically valuable and well-known member of the plant family Solanaceae. Potato is the host of many pathogens, including fungi, bacteria, Phytoplasmas, viruses, viroids and nematodes, which cause reductions in the quantity and quality of yield. Apart from the late blight fungus [Phytophthora infestans (Mont.) de Bary] viruses are the most important pathogens, with over 40 viruses and virus-like pathogens infecting cultivated potatoes in the field, among which Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato virus X (PVX), Potato virus A (PVA), Potato virus S (PVS) and Potato virus M (PVM) are some of the most important viruses in the world. In this review, their characteristics and types of resistance to them will be discussed.
