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:: 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.

localization of initial late blight infection
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:: Results of experiments with isolates A1 and A2 from populations occurring in Poland in the years 1993-1998 were compared. Mating types A1 and A2 did not significantly differ with respect of virulence spectrum, pathogenicity level and virulence diversity (Shannon index). After pairing isolates A1 and A2 formed oospores; their morphological characteristics were described. On selected fields a test was performed whether the oospores could play a role as a source of primary infection. Local populations occurring on three fields were characterized. Results obtained on investigated 3 separate fields, located in 2 voivodeships of southern Poland were compared. It was stated on the basis of the proportion of both mating type isolates, race complexity and diversity, that oospores could play a role as a source of primary infection, at least in one of localities in Boguchwała, podkarpackie voivodeship.
Drugi typ kojarzeniowy A2 został wykryty w Polsce w 1988 roku. Porównanie spektrum wirulencji i poziomu agresywności u izolatów obu typów kojarzeniowych A1 i A2 zebranych w latach 1993-1998 wykazało, że oba typy kojarzeniowe nie różnią się między sobą istotnie. Typ A2 nie stanowi większego bezpośredniego zagrożenia dla ziemniaka niż typ A1, lecz odgrywa rolę w procesie rozmnażania generatywnego. Oospory wytworzone w tkankach ziemniaka po skojarzeniu obu typów P. infestans mogą stać się, po przezimowaniu w glebie, drugim, obok zakażonych bulw, źródłem infekcji pierwotnej P. infestans. Aby odpowiedzieć na pytanie, czy oospory odgrywają rolę w wywołaniu infekcji pierwotnej, na polach ziemniaka dokonano scharakteryzowania lokalnych populacji P. infestans na 3 plantacjach ziemniaka. Porównanie wzajemnego stosunku izolatów obu typów kojarzeniowych oraz ocena złożoności i zróżnicowania ras wykazała, że oospory mogły być źródłem infekcji pierwotnej na polu w Boguchwale (woj. podkarpackie). Na innych polach patogen prawdopodobnie rozmnażał się na drodze wegetatywnej.

Tytuł:: Increasing the efficiency of potato breeding through marker assisted selection - general thoughts. Molecular markers for late blight resistance - when applied for breeders?

Tematy:: marker assisted selection

potato late blight resistance
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:: Pierwsze próby wykorzystania Internetu dla potrzeb monitorowania zagrożenia ziemniaka przez P. infestans w Polsce podjęto w latach 2001–2002 z zastosowaniem oprogramowania przekazanego stronie polskiej przez Duński Instytut Nauk Rolniczych. Istotny wkład w opracowanie rodzimego systemu internetowego wniosła również współpraca Instytutu Ochrony Roślin z Centrum Oprogramowania i Systemów Decyzyjnych w Niemczech realizowana w latach 2003–2007. W ramach tej współpracy strona polska zapoznała się z funkcjonowaniem opracowanego w Niemczech Systemu Informacyjnego dla Potrzeb Integrowanej Produkcji Roślin, oraz z organizacyjnymi aspektami funkcjonowania doradztwa rolniczego, realizowanego z wykorzystaniem internetowych wersji systemów decyzyjnych. Zdobyte tą drogą doświadczenia pozwoliły na opracowanie witryny internetowej służącej do przekazywania informacji o terminie rozpoczynania ochrony chemicznej ziemniaka przed P. infestans, określanym z wykorzystaniem modelu Ullricha i Schrödtera oraz o wynikach, prowadzonego przez służby doradcze, monitoringu plantacji ziemniaka.
First efforts aimed at application of Internet for the threat of potato by P. infestans in Poland were undertaken within the framework of cooperation between Institute of Plant Protection, and Danish Institute of Agriculture Science in 2001–2002. Significant contribution in development of native Internet based system was brought by cooperation between Institute of Plant Protection and German Central Institution for Decision Support Systems and Programmes in Crop Protection (Zentralstelle für Entscheidungshilfen und Programme im Pflanzenschutz, ZEPP) in 2003–2007. This cooperation enabled polish partners to acquaint with Information System for Integrated Crop Protection developed in Germany, and with aspects of extension service work realized with the help of Internet based decision support system. This knowledge enabled Polish partners to develop a native system for protection of potato against P, infestans. The system delivers information about late blight threat for potato, assessed by the model of Ullrich i Schrödter and results of monitoring conducted by Advisory Service on chosen potato plantations.

Opis:: W latach 2005–2007 w doświadczeniach polowych prowadzonych w IHAR, Zakładzie Nasiennictwa i Ochrony Ziemniaka w Boninie oceniano wpływ warunków klimatycznych (temperatura, ilość opadów) w miesiącach czerwiec-sierpień i odporności 32 wybranych odmian, na tempo szerzenia zarazy ziemniaka, termin zniszczenia 50% naci (teoretyczny termin zatrzymania gromadzenia plonu) oraz procent zniszczenia naci pod koniec sezonu wegetacyjnego. Najwyższe wartości ocenianych parametrów stwierdzono dla grupy odmian podatnych. Wartości parametrów malały wraz ze wzrostem poziomu odporności.
The field experiments conducted in the years 2005–2007 at the Plant Breeding and Acclimatization Institute, Department of Seed Science and Plant Protection in Bonin were aimed to estimate the influence of weather conditions (temperature, rainfall) in the period June-August and of the level of resistance of 32 selected potato cultivars on the rate of late blight development, time of 50% haulm destruction and the percentage of haulm destruction at the end of a growing season. The highest values of estimated parameters were recorded for the group of susceptible cultivars. The values of parameters decreased with increasing level of potato resistance to late blight.

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
