Opis:: Inheritance of tomato resistance to P. infestans was studied in progenies of crosses of resistant accessions: West Virginia 700, Ottawa 30, PI224675 and the variety New Yorker and also of the variety West Virginia’63 and resistant breeding lines crossed with susceptible forms. Populations of F1, F2, parents and resistant standards were evaluated for resistance to late blight using the test on seedlings grown in liquid medium. Resistance of the accessions West Virginia 700, Ottawa 30 and PI224675 was found to be identical and determined by the same genes: Ph-1 and Ph-2. It has not been recognized if these accessions carry other genes, neither if the variety West Virginia’63 and lines of equal resistance possess other genes beside Ph-2.

Opis:: A comparative study of different parameters calculated for foliage resistance of potato to Phytophthora infestans (Mont.) de Bary was conducted on the data for 27 cultivars and one prebreeding clone in field assessment in 2003 at BAZ Groß Lüsewitz. Relationships between the parameters and maturity were determined by linear regression. The strongest associations with maturity were found for the relative area under the disease progress curve (RAUDPC), delay of attack, and attack on a determined date (r2 = 0.47-0.52). The least association with maturity was found for foliage blight resistance at Groß Lüsewitz, FBRGL (r2 = 0.03), calculated by using a maturity-dependent section of the disease progress curve. The apparent infection rate (AIR), RAUDPC and delay of attack could only explain below 50% of variability of FBRGL. The method for calculation of foliage resistance in breeding developed at BAZ and named FBRGL is described in detail, and the usefulness of the different methods for evaluation of resistance, management of plant protection and breeding is discussed.

Opis:: Protoplast fusion was used to produce more than 500 symmetric interspecific somatic hybrids between wild Solanum species, which belong to the series Pinnatisecta, Etuberosa and S. tuberosum L. cultivars or potato breeding clones. The used genebank accessions of S. cardiophyllum and S. tarnii were resistant to Phytophthora infestans, while the accessions of S. cardiophyllum, S. tarnii, as well as of S. etuberosum, were also highly resistant to PVY (strains: PVYO, PVYN, PVYNTN, PVYC, PVYN Wilga). In most fusion combinations vigorous and genetically stable hybrid material has been selected. A number of interspecific somatic hybrids were fertile and could be backcrossed with cultivated potato. The use of detached leaf and tuber tests and mechanical inoculation, grafting and virus transmission by vectors, revealed that several somatic hybrids and backcross (BC) clones were resistant to foliage and tuber blight, as well as to PVY.

Opis:: In four diploid and four tetraploid families correlations were evaluated between resistance to Phytophthora infestans of leaflets, tuber slices and whole tubers as well as correlations between three aspects of resistance and maturity or tuber shape regularity. A virulent P. infestans isolate was used for inoculations. Only in the family D4 a significant positive correlation was found between all the three aspects of resistance. Genotypes with susceptible leaflets and resistant tuber slices were not identified in any family. In some families genotypes with resistant whole tubers and susceptible tuber slices were found; the family D5 was found to have genotypes in which resistance of leaflets was associated with susceptibility of tuber slices. The resistance to P. infestans of leaflets or tuber slices tended to be negatively correlated with both early maturity and regularity of tuber shape.

Opis:: New sources of Phytophthora infestans (late blight) resistance are studied in two groups of diploids: complex Solanum hybrids and clones of pure wild Solanum species. In more advanced studies complex hybrids of Solanum verrucosum, S. phureja and S. microdontum were involved, which were intercrossed in various combinations. In this group, clones with resistance both in leaflets and tubers have been selected. In addition, highly resistant to late blight hybrids are outstanding in chosen quality traits. Resistance to P. infestans identified in the advanced hybrids has been successfully transferred into 4x level with various extent. The second group of sources recently included in research covers about 110 clones of five wild Solanum species (S. berthaultii, S. kurtzianum, S. michoacanum, S. ruiz-ceballozii and S. pinnatisectum). In 1999-2003 preselection of leaflets and tuber resistant clones was performed. Selected clones have been simultaneously characterized for male fertility and big pollen grains (2n) formation.

Opis:: A study on the expression of resistance to Phytophthora infestans of wild potato plants grown in a climatic chamber, in a screenhouse and in the field was performed in two experiments. In the first experiment 12 populations of Solanum acaule were tested. Detached leaves from field-grown plants appeared to be less resistant than detached leaves from chamber-grown plants. In the second experiment resistance responses to inoculation with P. infestans of 24 Solanum species, grown in the field and in the screenhouse were compared. In 18 populations belonging to 11 species the predominance of resistant plants was found either when plants were grown in the field or when plants were grown in the screenhouse. Within 12 tested populations no difference in resistance was observed because of high susceptibility of plants, irrespective of grown conditions. Two populations showed the same level of resistance under both grown conditions.

Opis:: The tuber reaction to Phytophthora infestans was evaluated in individual genotypes of four diploid and four tetraploid potato families, their parents and standard cultivars. The genotypes were tested several times. Two testing methods were used, based on evaluation of tuber slices or whole tubers, respectively. All inoculations were done with MP 245, a fungus isolate with a broad virulence spectrum. If the reaction of tuber slices was evaluated, the distribution of genotypes in several families deviated considerably from a normal one. In some distributions more than one peak was detectable, indicating segregation of major genes. Genotypes transgressive in resistance were found in four families. If the reaction of whole tubers was evaluated, the distribution of genotypes did not deviate significantly from a normal one. Genotypes transgressive in resistance were found in one family. The tuber reaction to P. infestans depended to a large extent on testing conditions.

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:: Potato families, segregating for resistance to Phytophthora infestans, were tested repeatedly to evaluate the distribution of resistance to P. infestans, the repeatability of testing results and correlation between resistance and some other characters. Four diploid and four tetraploid families were evaluated together with their parents and with potato cultivars used as standard. For all inoculations a virulent fungus isolate MP 245 was used. Leaflets were collected from plants growing in the field (summer tests) or in a glasshouse (autumn and spring tests). Segregation of major genes determining resistance was detectable in most families. In families originating from mating a resistant parent with a susceptible partner some progeny genotypes with resistance level of the resistant parent could be identified. In families originating from two parents showing only some resistance, a transgression of resistance could be found in the progeny. The expression of resistance depended on testing conditions. Some genotypes were consistently superior or inferior in resistance under all testing conditions, but often repeated evaluations of genotypes did not provide consistent results and significant interactions genotypes x tests were detectable.

Opis:: The genetic resistance of potato varieties can be utilized to lower the fungicide rates used for plant protection against late blight. The very resistant varieties can be protected with half the rate of fungicide without negative effect on efficiency of the control.
Odporność genetyczna odmian ziemniaka może być wykorzystana do zmniejszania dawek fungicydów, stosowanych w ochronie plantacji ziemniaka przed zarazą. Odmiany bardzo odporne (Meduza) mogą pozostawać niechronione lub mogą być chronione fungicydami, stosowanymi w dawkach zmniejszonych o połowę (dla uniknięcia problemów ewentualnie zwiększonej presji infekcyjnej patogena w ciągu okresu wegetacji). Uzyskane wyniki wskazują, że odmiany podatne na zarazę (Karlena) wymagają ochrony prowadzonej w pełnych zalecanych dawkach fungicydów w każdym roku, niezależnie od presji infekcyjnej patogenu. Dla niektórych odmian, nawet o średniej odporności (Panda) wystarczające są dawki zmniejszone do 50-75% by skutecznie hamowały rozwój zarazy w niektóre lata. Różne odmiany mogą reagowa w różny sposób na zmniejszanie dawek fungicydów. W przeprowadzonych badaniach stwierdzono istotne współdziałanie odmian i dawek fungicydowych. Uwzględnienie genetycznej odporności odmian ziemniaka na zarazę pozwala obniża dawki stosowanych fungicydów, z zachowaniem zadawalającej skuteczności ochrony, co może by ważne ze względu na ochronę środowiska.

Opis:: Phytophthora infestans, organizm wywołujący zarazę ziemniaka jest najgroźniejszym i najważniejszym ekonomicznie patogenem ziemniaka. Pomimo długiej historii hodowli odpornościowej na P. infestans, przy wykorzystaniu zarówno genów R jak i genów o małych efektach, do tej pory nie udało się uzyskać satysfakcjonującego poziomu trwałej odporności u odmian o krótkim okresie wegetacji. Powodem tego jest fakt, iż wysoki poziom odporności polowej na P. infestans jest silnie sprzężony z długim okresem wegetacji roślin ziemniaka. Przyczyny tego związku mogą mieć charakter fizjologiczny i genetyczny. Wyniki badań molekularnych potwierdzają, iż długość wegetacji oraz pozioma odporność na P. infestans mogą być warunkowane przez te same geny o efekcie plejotropowym lub przez geny bardzo silnie sprzężone. Możliwości uzyskania odmian wczesnych o wysokim i trwałym poziomie odporności na drodze konwencjonalnej hodowli należy upatrywać w zastosowaniu nowych źródeł odporności.
Phytophthora infestans, the causal agent of the late blight is the most dangerous and economically important potato pathogen. In long history of resistance breeding against P. infestans both, R genes and genes with small effects were used. Until now early cultivars with high level of durable resistance do not exist. The main reason for the lack of early resistant cultivars is relationship between high levels of field resistance and late maturity. Nature of this relationship might be both physiological and genetic. Molecular study of earliness and late blight resistance shows that both traits may be the results of pleiotropic effects of the same genes or independent but very closely linked genes. New sources of resistance are required for introduction of high level of durable resistance to late blight into early genotypes by conventional breeding.
