Opis:
A laboratory test for evaluating the tomato leaf resistance to Phytophthora infestans in the seedling stage has been developed. The test is suitable for evaluation of breeding lines and selection within large populations. The following standard varieties and accessions representing a whole range of variability of known resistance were used: Moneymaker, New Yorker, West Virginia`63, West Virginia 700 and Ottawa 30. Various P. infestans isolates were used in the tests. Tomato seedlings grown in a liquid medium were cultured and tested in a growth chamber. The infection of individual seedlings was evaluated using 9-degree logistic key and data were statistically estimated. The results were reproducible in the same growth   conditions. Ranking of infection degree was as follow: Moneymaker ≥ New Yorker > West Virginia`63 > West Virginia 700 = Ottawa 30 irrespectively of test conditions or the isolates applied. The laboratory ranking was consistent with field observations. The results of tests depended on concentration of liquid medium (lower infection at lower concentration), on the isolate used and its spore concentration. The method proposed meets all requirements necessary for breeding and research as a routine method for evaluation of the tomato leaf resistance to P. infestans.

Opis:
This study describes a newly developed index for predicting and forecasting the first (and potentially subsequent) timing of fungicide application against late blight in potato crops based on weather variables measured close to the crop. Inputs for index calculation were the following: daily minimum temperature, mean relative air humidity and daily precipita- tion. The decisive moment in the process of forecasting is the sum of daily index values for the previous 5 days. The index was tested in various localities of the Czech and the Slovak Republics for several years with a relatively high success rate exceeding the accuracy of previously applied strategies – NoBlight and negative prognosis. In comparison to the men- tioned methods, the calculated index corresponded very well to long-term wet periods and indicated the first application date correctly. In years with no wet periods (in this case, 2015 and 2017), it allowed postponing the first application and reducing the number of required sprays during the growing season. The method does not depend on determining the emer- gence date, so it can be presented on the internet without cooperation with specific growers in a given locality, and thus supply information for a wider range of users. With knowledge about crop development and the degree of resistance to late blight of grown varieties, users can subsequently choose a specific fungicide and its application date.

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.

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:
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:
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:
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.

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:
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:
Although development of potato cultivars resistant to late blight has long been one of the primary goals of potato breeding programs, several different methods of field resistance evaluation have been used by potato breeders. 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.
