Opis:
Changes in the occurrence of the initial late blight symptoms have been noted in some regions of Poland. Observations of potato crops showed that occurrence of the primary infections and blight symptoms is sometimes on the stem rather than on the leaves. It was confirmed that in both cases, a cause of late blight was the same species Phytophthora infestans. Surveys of many potato crops done in 1997-1999, around Poland enabled assessment of the incidence of stem blight in Poland. In 1997 - 80.5%, 1998 - 65.2% and in 1999 – 72.4% of observed crops were primary affected with late blight on stems. Stem form of the disease appeared more often in the years with less rainfall in the period from June to July. The largest number of genotypes with initial blight symptoms on stems was observed among first early clones and cultivars. Glasshouse experiments confirmed the importance of stem lesions in decreasing yield and increasing tuber infection. Results confim that blighted tubers were the least probable source of the late blight appearing on stems.

Opis:
All definitions for integrated control agree that maximum emphasis should be put on prevention by using resistant cultivars and cultural measures. Moreover, the use of plant protection products should be limited to the essential minimum using Decision Support Systems (DSSs) that integrate and organise all relevant information. Computer-based DSSs that require weather information and regular late blight scouting inputs have been developed and validated in a number of European countries. In the frame of the EU concerted action “European network for development of an integrated control strategy of potato late blight (EU.NET.ICP)” several DSSs were validated in 1999-2001. The overall conclusion was that in most cases the use of DSSs combined a good disease control with a reduction of fungicide input. The DSSs can be used as a PC-version but more and more, parts of information are delivered to users by phone, fax, e-mail, SMS and websites on the Internet. An important task for the near future is to update the DSSs with information on the epidemiology of the new aggressive population of Phytophthora infestans. Issues such as (1) the influence of temperature and relative humidity on the infection process, (2) the role of primary inoculum sources (seed, oospores, volunteers, dumps), (3) the role of secondary inoculum sources (distance, severity), (4) control of early blight and (5) resistance ratings for foliar and tuber blight have to be addressed in order to be able to formulate a robust control strategy that effectively controls late (and early) blight with a minimum input of fungicides.

Opis:
At SCRI, wild species and clones of Solanum tuberosum are assessed for resistance to late blight in order to study the genetics and breed for resistance. Glasshouse progeny tests for foliage and tuber blight resistance, using true seedlings, are described. These enable the rapid screening of accessions of wild species, and the selection of the most resistant progenies in a breeding programme within one year of crossing. Assessment of the foliage resistance of clones is carried out in glasshouse tests of whole plants in flower-bud, and field trials using infector plants inoculated in the glasshouse with a complex race of Phytophthora infestans. The glasshouse test provides a reliable method of identifying R-genes and the virulence characteristics of blight isolates. The field trial gives the best estimate of field resistance and is being used to develop marker-assisted selection. Both tests are used to study the inheritance of resistance, to locate quantitative trait loci (QTL) and R-genes, and to select the most resistant clones. The tuber resistance of clones is assessed by spray-inoculating whole, immature, field-grown tubers on the day of harvest. However when large numbers of clones are involved, e.g. in the location of QTL, this is impractical, so glasshouse-grown tubers are dip-inoculated.

Opis:
Despite many breathtaking breakthroughs in the area of crop genetics and genomics, plant breeding still widely depends on the methods that had been worked out almost a century ago. This is not because commercial plant breeders are overly conservative but because the new knowledge lacks efficient and economical tools that would permit their application in practice. Breeders desire supporting technologies that would facilitate laborious and time-consuming screening in the field and laboratory. In particular, resistance screening often cannot be performed satisfactorily as the necessary disease pressure and appropriate pathogen populations may be unavailable. In potato breeding, specific and often complex resistances need to be developed, at the same time maintaining high levels of quality and culinary characteristics. Therefore, it is worthwhile to revisit the facts that comprise the progress in genetics of disease resistance and to analyze current technologies of genotyping and marker assisted selection, with the objective to detect those parameters that limit the efficiency of methods for commercial application. Selection in potato for resistance to late blight will be highlighted as an example. Maps, genes and markers for resistance have been identified – how universal are they? Single genes and quantitative trait loci for race-specific and race non-specific resistance are known – how efficient is their use? Marker technologies based on polymerase chain reaction and DNA hybridization have been developed that are far more efficient than first-generation technologies – is their use in commercial breeding economical? By discussing these issues concepts will emerge that help to pave the way for marker assisted selection (MAS) in potato breeding. The most important parameters required for economical MAS include to have a clear idea of the traits to be selected for, to use proven, reliable markers, to have in place a robust system for the collection and management of DNA samples, and to use technologies whose total cost is below or equal to the cost of the conventional methods. The most striking advantages of MAS are that a breeder will obtain more information than by conventional methodology, the information will be more precise, field labour can be saved and in that way the breeding process will be intensified. The implementation of the new technology could lead to even closer collaboration of breeders and scientists. Possible disadvantages include the relative increase of laboratory and computer work within the breeding program, and possibly higher costs during the implementation phase of the new technology.

Opis:
Changes in population of Phytophthora infestans can greatly influence the time of potato late blight appearance in potato crops. The late blight monitoring system makes it possible to evaluate reliability of the forecast provided by decision support systems that are applied in potato protection and in consequences defends in practice potato crops from early appearing infections. The first steps in creating Polish internet monitoring system in potato protection against late blight were based on observations carried out by advisers from the Plant Protection Inspectorate in Lublin voivodeship in the years 2001-2002. The conducted evaluations were part of the Polish-Danish research project “Development of an Internet based DDS for Cereal Diseases and Potato Late Blight in Poland, 2001-2002”. In 2003, the observations were also conducted in four other voivodeships. The collected results indicate that it is feasible to recognize primary early infections manifested as singular necroses on potato plants. The earliest infections were most frequently recorded on susceptible potato cultivars. In two cases in 2003, early attacks were recorded at plant growth stage of 30-31 (in 0-99 BBCH scale for potato). In most cases the first infection symptoms appeared at the growth stage exceeding 37. This indicates that very early infections caused by oospores from soil were not common in the inspected areas.

Opis:
The resistance to late blight (LB) is considered as a factor of major importance among resistances to potato pathogens. For four last decades more work has been done on potato resistant to Phytophthora infestans than on breeding for resistance to any other potato disease. Many sources of resistance have been known to breeders for many decades, but the results of their utilization are still disappointing. The difficulties in breeding for LB resistance were assessed by 39 participants of the survey organized for the Global Initiative on Late Blight (Zimnoch-Guzowska and Flis 2002), who indicated several major factors hampering progress in this area. The following factors found to be the most important bottle necks are discussed in the paper: (i) identification and utilization of new sources of resistance, not sufficient agronomic value of the used resistance sources; (ii) combination of earliness with LB resistance; (iii) complexity of genetic determination of LB resistance; (iv) combination of foliage and tuber resistance; (v) screening methods applied for resistance evaluation; (vi) cost of selection for resistance; (vii) lack of molecular markers (MAS) applicable to selection for LB resistance.   limitations, Phytophthora infestans, potato, resistance breeding

Opis:
Analizę oparto na wynikach ścisłego doświadczenia polowego przeprowadzonego w latach 1998–2000 w stacji doświadczalnej w Uhninie. Obiektem badań było jedenaście średnio późnych (Ania, Anielka, Arkadia, Fregata, Grot, Klepa, Omulew, Rybitwa, Rywal, Salto, Vistula) i pięć późnych (Dunajec, Hinga, Jantar, Meduza, Wawrzyn) odmian ziemniaka. Nawożenie mineralne na stałym poziomie stosowano wiosną przed sadzeniem, zaś organiczne — jesienią. Zdrowotność sadzeniaków była porównywalna (C/A). W doświadczeniu określono plon bulw, suchą masę oraz plon suchej masy. Plony potencjalne obliczano wg metody van der Zaag z modyfikacją Mazurczyka. Celem było określenie wpływu aktywności fotosyntetycznej na potencjał plonowania średnio późnych i późnych odmian ziemniaka w warunkach polowych a także ocena możliwości zwiększenia produktywności i produkcyjności tych odmian. W warunkach wschodniej części Polski potencjalne plony bulw średnio późnych odmian ziemniaka mogą być o 35% wyższe od plonów rzeczywistych, natomiast w przypadku odmian późnych o 22,2%. Stosunek plonów aktualnych do potencjalnych na poziomie 0,66 zapewnia już uzyskiwanie dobrych plonów, zarówno średnio późnych, jak i późnych odmian ziemniaka. Czynnik genetyczny najsilniej decydował o zmienności fenotypowej zawartości suchej masy, czynniki siedliska najsilniej determinowały zmienność fenotypową plonu bulw i plonu suchej masy, zaś współdziałanie odmian i lat oddziaływało najsilniej na plon suchej masy.
The analysis of potato yield is based on a field experiment carried out at the Uhnin experiment station in the years 1998-2000. Tuber yield, dry matter and dry matter yield were determined in eleven medium-late (Ania, Anielka, Arkadia, Fregata, Grot, Klepa, Omulew, Rybitwa, Rywal, Salto, Vistula) and five late (Dunajec, Hinga, Jantar, Meduza, Wawrzyn) cultivars. The mineral fertilization was applied before planting in spring, at a constant level, to the soil fertilized with manure in autumn. The health status of seed material was similar (C/A class). The potential yield was calculated using the van der Zaag method, with modification of Mazurczyk. Under the conditions of central-eastern Poland the potential yield of medium-late cultivars could be 35% higher than the actual yield, in case of the late cultivars the difference was 22,2%. The 0.66 ratio of actual to potential yield was sufficient to obtain good yields for cultivars of both maturity groups. The genetic factor strongly influenced the phenotypic variation of dry matter, while the habitat determined the phenotypic variation of tuber yield and dry matter yield. The interaction of cultivars with years affected most highly the yield of dry matter.

Opis:
Potato breeders and phytopathologists have been conducting the studies on Phytophthorainfestans (Mont.) de Bary at the Priekuli Plant Breeding Station since 1962. The varietal resistanceis very important in potato breeding programme. The trials in collaboration with the Institute ofPhytopathology of Soviet Union (Russia) were done in 1974-1990. The investigations were focusedon races of P. infestans. The changes of races were assessed using a trap method, according to theinvestigation programme, like in each of the republics of the Soviet Union.At the beginning of investigations (1960s and 1970s) races 1, 4 and 1.4 of P. infestans were thepredominant ones in Latvia, but in the 1980s complex races 4.10.11, 1.4.7.8.10.11, 1.3.4.7.8.10.11and 1.2.3.4.7.8.10.11 were more widely distributed.Different foreign varieties, mostly from the Netherlands, were introduced in Latvia in the 1970s.This resulted in a very rapid differentiation of late blight races. The enhanced aggressiveness of P.infestans isolates was due to an increasing number of races in population. The earlier appearance ofinfection in potato fields was recorded. The presence of a mating type A2 was stated in Latviansamples in 1987. Because all tested races had been recognized in a population, and the conception ofresistance breeding had been modified, the trials were stopped in 1990. The resistance based onspecific resistance genes was the main direction in the 1960s and 1970s. From the 1980s, impor-tance of the field resistance has greatly increased and this type of resistance is the most significantin the current breeding programme. The trials in organic field proved the acceptable level of fieldresistance to P. infestans of three medium late varieties: Sigunda (previous name Undine), Beteand Zile. These varieties have been bred at the Priekuli Plant Breeding Station and included intothe Latvian Plant Varieties Catalogue.

Opis:
The effective management of protection against Phytophthora infestans must be established on the perfect knowledge of the pathogen. From a practical point of view this means identification of races and mating types as well as the pathotypes resistant to systemic compounds of fungicides. The main goal of our project was to characterize populations of late blight, especially in the most important area of seed potato production. Recognition of races and mating types and evaluation of resistance to metalaxyl of the isolates in potato-growing area were performed in laboratory tests. Isolates of late blight for laboratory tests were collected in commercial and research potato crops in the regions of Poprad and Kežmarok. The first occurrence of metalaxyl-resistant strains was noticed in 1999, and the greatest incidence was recorded in 2000. In the following years a significant decrease was observed. This was due, among others, to omitting fenylamide fungicides in crop protection in our region. The occurrence of isolates virulent to potato with R2, R5, R9 and R11 genes was noted neither in 1996 nor in 1997, and tested isolates had maximum six virulence factors. Since 1999, the occurrence of isolates with seven, eight or even ten virulence factors has been recorded. Presence of A2 mating type was not confirmed in our area until 2002. In 2003, more A2 than A1 isolates were found. It is likely that problems concerning the ability of oospores to survive in soil as well as sexual reproduction of the pathogen may appear also in our potato-growing area.

Recently, within the EucaBlight network (www.euroblight.net), common methods of late blight evaluation have been agreed on, and these methods are currently highly recommended for use by all those interested in evaluating the resistance of the potato to late blight. Here, we describe a method of evaluating potato resistance in field conditions routinely used at Młochów Research Center, which is compliant with recommendations of the EucaBlight protocol.

Opis:
The procedure of evaluation is based on mathematical simulation model of the late blight (LB) development in combination with laboratory testing of detached leaflets artificially inoculated with Phytophthora infestans. An incubation period, amount and sizes of lesions and sporulation capacity are estimated. Each couple “tested Phytophthora isolate and tested potato cultivar” is compared with a standard couple “Phytophthora isolate N161 and standard cultivar”. A simulator on the base of these data calculates area under the curve for LB development and yield loss due to LB for a situation when a yield loss of a standard cultivar infected with a standard isolate is equal 35%. Comparison of a new rapid laboratory method and field methods showed satisfactory correlation. Resistance to late blight was evaluated for 47 potato cultivars with the new method. It was also shown that some variations in foliar aggressiveness existed among P. infestans populations from different regions. Supported by ISTC grant #1640.

Ochrona prowadzona wg systemu NegFry pozwoliła na istotne ograniczenie rozwoju zarazy ziemniaka i zredukowanie liczby zabiegów fungicydowych o 2 w porównaniu do konwencjonalnej metody ochrony (7 zabiegów).
The assessment of usefulness of a decision support system (DSS) NegFry for chemical control of late blight (Phytophthora infestans) was carried out at the Plant Breeding and Acclimatization Institute, Department of Potato Protection and Seed Science in Bonin in the years 2007–2008. The DSS NegFry was compared to different potato protection systems. The results obtained show that plant protection performed according to NegFry system significantly restricted late blight development and reduced the number of fungicide treatments by two in comparison to the conventional protection method (7 treatments).

Opis:
Ziemniak (Solanum tuberosum L.) jest jedną z ważniejszych roślin uprawnych na świecie. Roczna produkcja wynosi około 340 mln ton, co umieszcza go na czwartym miejscu wśród roślin użytkowych. Produkcję ziemniaków znacznie obniża choroba - zaraza ziemniaka, wywoływana przez grzybopodobny patogen Phytophthora infestans (Mont.) de Bary należący do Oomycetes. Patogen ten odnosi sukces dzięki białkom - efektorom wydzielanym w czasie interakcji z gospodarzem. Identyfikacja i poznanie funkcji białek efektorowych jest ważne dla zrozumienia oddziaływań patogenów z roślinami i może znaleźć praktyczne zastosowanie w hodowli odpornościowej. Roślina broni się przed infekcją produkując białka odporności R. W niniejszej pracy podsumowano dotychczasową wiedzę na temat oddziaływań efektor — białko odporności R na przykładzie patosystemu ziemniak — P. infestans. Przedstawiono dwie klasy efektorów, omówiono model roślinnego systemu odpornościowego i zaprezentowano kilka przykładów działania najlepiej zbadanych efektorów.
Potato is one of the most appreciated crops in the world, with total production near 340 million tons making it the fourth most important crop plant. Potato production is severely reduced by late blight caused by Phytophthora infestans. This pathogen is so successful thanks to proteins secreted during interaction with the host — effectors. The identification and knowledge of functions of a wide variety of effector proteins are very important for understanding the interactions of plants with pathogens and may find practical use in resistance breeding. The plant is defended by resistance (R) proteins. In this review the knowledge about interactions between effectors and R proteins was summarized with potato — P. infestans pathosystem as an example. Two different classes of effectors were presented. The plant immune system model was discussed as well as the host responses to infection. We presented examples of the most studied effectors which employ different mechanisms for evading recognition by the resistance proteins.
