Opis:: Tobacco (Nicotiana tabacum L.) is an important industrial crop. Among the diseases causing losses in tobacco cultivation, viral ones are of particular importance due to the very low effectiveness of chemical protection allowing only for vector control. The greatest threat to tobacco cultivation in Poland and in many countries of the world is posed by potato virus Y (PVY), tomato spotted wilt virus (TSWV) and, in recent years, the increasingly frequent tobacco mosaic virus (TMV). The genetic resources studies carried out in the genus Nicotiana have shown a wide variation in species resistance, assessed biologically, serologically and molecularly, depending on the virus used and, in the case of PVY, also on the specific isolate. The results of the assessment of resistance in Nicotiana accessions presented in this paper, gathered from literature data as well as from our own research, allow us to broaden and systematise our knowledge on the sources of resistance to viral diseases. This is the only such an extensive study in this field. It provides an excellent information base for the appropriate selection of accessions for use in resistance breeding.

Opis:: One of the most important threats to tobacco cultivation is the Potato virus Y (PVY). Sources of resistance to PVY are found both in Nicotiana tabacum cultivars and in wild Nicotiana species. The high variability of the virus and the ability to break the existing resistance make it necessary to search for new resistance sources or to combine the ones that are already known. The aim of the study was to combine va resistance of two cultivars VAM and Wiślica, showing resistance to most PVY isolates, with the wild Nicotiana africana species, which is immune to all known PVY isolates. Due to the significant genetic distance between these species, the seedlings of the obtained F1 hybrids were not viable. In order to obtain viable hybrids, cotyledon in vitro cultures were used. Growth and development of the callus, as well as plant regeneration were differentiated depending on the maternal component used in the crossing with N. africana. The cotyledons of hybrids derived from cultivar VAM regenerated more efficiently, as 88 amphihaploid hybrid plants were obtain from this maternal parent. In contrast, only 27 amphihaploid hybrid plants were derived from cultivar Wiślica. Infertility of amphihaploid plants hampered their use in the breeding process. In order to restore fertility, the process of organogenesis from stem piths under in vitro conditions, was used. The degree of ploidy of regenerated plants was determined using flow cytometry. Despite the use of the same in vitro culture conditions for all the objects, a significant influence of the maternal component on the number of obtained regenerants and on the degree of their ploidy level was observed.

Opis:: Potato virus Y (PVY) is one of the most destructive viruses infecting potato in Egypt and worldwide. Recent research has shown that a necrotic PVY-NTN strain is infecting potato in Upper Egypt. Chemical control is not effective to control this viral pathogen. An alternative to control PVY infecting potato is using a mild PVY strain to elicit systemic cross protection in potato plants against infection with a severe necrotic strain of PVY. Results of this study showed that a PVY necrotic strain produced a significant lesser number of local lesions on diagnostic plants (Robinia pseudoacacia L.) when these plants were treated first with a mild PVY strain. Data obtained from greenhouse and field experiments indicated that treatment of potato plants (variety Burna) with a mild PVY strain significantly protected potato from infection with a severe necrotic PVY strain, and resulted in a significant increase in tuber yield compared with infected plants without prior treatment with a mild PVY strain. The highest increase in potato tuber yield was obtained when potato plants were inoculated with a mild PVY strain 3 days before challenging with the severe necrotic PVY strain. This study proved that using a mild strain of PVY can significantly protect potato plants from infection with a severe strain of this virus under both greenhouse and field conditions and can present a potential method to reduce losses due to infection of this virus in Assiut governorate and Upper Egypt.

Opis:: The induction of acidic proteins in seven potato cultivars (Drop, Atol, Sokół, Tarpan, Jagna, Irga, Darga) was analysed. It has been found that induction of the acidic pathogenesis-related (PR) proteins in potato leaves infected with a necrotic strain of potato virus Y (PVY-N Wi) is specific to each cultivar.

Opis:: The tuber necrotic strain of Potato virus Y (PVYNTN) causes widespread disease and has severe negative effects on the growth and yields of plants, especially those of the Solanaceae family. The consequences of residual toxicity and non-biodegradation of synthetic chemicals and pollution of the environment has led to investigations into new non-toxic and biological treatments to control plant viral diseases. Ethanolic extracts of Bowiea volubilis (bulbs), Cotyledon orbiculata (leaves), Gomphocarpus fruticosus (leaves), Merwilla plumbea (dry and fresh bulbs), Nerium oleander (leaves), and the fruits and leaves of Strophanthus speciosus, were evaluated against PVYNTN in vivo and in vitro. At a concentration of 20 mg · ml−1, ethanolic extracts of Strophanthus speciosus (leaves) and fruits (50 mg · ml−1) significantly reduced the expression of PVYNTN symptoms on tobacco plants in vitro without affecting the normal growth and development of the plant. Similarly, at 50 mg · ml−1, N. oleander, C. orbiculata and B. volubilis (fresh bulbs) and S. speciousus leaves at 20 mg · ml−1 extracts showed significant differences in PVYNTN symptoms in the in vivo experiment. Strophanthus speciosus leaf and fruit extracts showed significant inhibition in the in vitro and in vivo assays and demonstrated that S. speciosus has potential to be used as an antiphytoviral treatment.

Opis:: Potato is one of the most important food crops with a capacity to abate hunger among farmers in the region. However, its productivity has stagnated and remained low due to poor agronomic practices applied by smallholder farmers. To avert this situation, dissemination through training of already existing better technologies and practices should be prioritized. A lot of research has been done with better recommendations- use of disease-free tuber seeds from high yielding and tolerant varieties, adequate application of balanced nutrients, timely scouting and integrated management of pests and diseases and good harvesting practices are available for immediate adoption. The adoption and dissemination could be facilitated by currently existing policies that promote cross-border movement and diffusion of research technologies and new varieties.

Opis:: Monitoring of aphids - vector of potato diseases virus - continued in Poland for 30 years in 5 localities, indicated some changes in pressure exerted by these insectes. The biggest differences were observed for Macrosiphum euphorbiae (Thom.) and subsequently for Aphis frangulae Kalt. and Aulacorthum solani Kalt. Reduction in population of these aphids has been observed according to elapsing time in all five localities. In case of Myzus persicae (Sulz.) or Aphis nasturtii Kalt., these changes involved decrease or increase of the pressure, depending on the locality.
W latach 1969-1998 w 5 miejscowościach w różnych rejonach Polski prowadzono obserwacje (odłowy do żółtych szalek) mszyc, wektorów wirusów ziemniaka. Stwierdzono zmienność presji tych owadów. Największe różnice zanotowano u Aphis frangulae Kalt. Na przykład w Szyldaku udział procentowy osobników tej mszycy w latach 1969-1978 wyniósł 62 procent, a w latach 1979-1988 i 1989-1998 odpowiednio 28 i 9 procent. Zbliżone dane zanotowano również w innych miejscowościach. W miarę podobny trend wystąpił u mszyc Macrosiphum euphorbiae (Thom.) i Aulacorthum solani Kalt. Zmniejszenie liczebności świadczy o malejącym znaczeniu wymienionych gatunków mszyc jako wektorów wirusów. W odniesieniu do Myzus persicae (Sulz.) i Aphis nasturtii Kalt. stwierdzono wzrost lub spadek liczebności w miarę upływu lat w zależności od miejscowości.
