Opis:
Przedmiotem badań była charakterystyka kwitnienia jedenastu dzikich gatunków i podgatunków żyta pochodzących z Europy i Azji Środkowej, oraz gatunku uprawnego Secale cereale ssp. cereale, odmiany Walet. Celem badań była wiec charakterystyka biologii kwitnienia gatunków z rodzaju Secale L. Poznanie biologii kwitnienia jest przydatne do krzyżowań oddalonych, ponieważ synchronizacja terminów kwitnienia odgrywa podstawową rolę w prawidłowym przeprowadzaniu krzyżowań i wytworzeniu mieszańców. Porównane zostały takie cechy jak: budowa kłosów (budowa morfologiczna kłosków, długość kłosa, liczba kłosków w kłosie, zbitość kłosa), żywotność ziaren pyłku, termin i długość kwitnienia, stopień samoniezgodności kłosów z poszczególnych gatunków. W wyniku prowadzonych badań i obserwacji ustalono, że wszystkie gatunki i podgatunki mają podobną budowę morfologiczną kłosów, różnią się istotnie statystycznie niektórymi cechami ilościowymi: długością kłosa, liczbą kłosków w kłosie i zbitością kłosów. W roku prowadzenia obserwacji kwitnienie w rodzaju Secale było rozłożone w czasie. Gatunek najwcześniejszy rozpoczynał kwitnienie 18.05, a gatunek najpóźniejszy rozpoczynał kwitnienie 16.06. Gatunki Secale silvestre i Secale strictum ssp. africanum zawiązywały ziarniaki przy samozapyleniu. Pozostałe gatunki i podgatunki jako obcopylne i samoniezgodne nie zawiązywały ziarniaków przy samozapyleniu
The purpose of the study was to characterize the flowering of different species in the genus Secale. Good knowledge of blooming biology is needed for making distant crosses because synchronization of flowering is important for proper performance of the treatment. Investigations were carried out on eleven wild rye species coming from Europe and Middle Asia, and on a cultivated species Secale cereale ssp. cereale, cultivar Walet. The following elements of flowering were compared: structure of inflorescences (morphological structure of spikelets, ear length, spikelet number per ear, ear density), viability of pollen, flowering dates and level of self-incompatibility in species. All the species and subspecies under study were found to have the same morphological structure and to differ significantly in ear length, number of spikelets per ear and ear density. In the year of investigations the duration of flowering in Secale species was largely extended and it lasted from 18 May till 16 June. The species Secale silvestre and Secale strictum ssp. africanum set seeds in the self-pollination process. The other species and subspecies, being self-incompatible ones, did not bind grains in this process.

Opis:
Introduction. Among herbal plants, most cases of allergic reactions, like seasonal inflammation of nasal mucosa, conjunctivitis and pollen asthma, are related to the allergens from grass pollen. As the blossoming and pollination of rye is known to start the pollen season of grasses, information about the airborne rye pollen count permits alerting the people allergic to certain allergens contained in rye pollen. An important cause of allergy is also the pollen from wormwood, blossoming in late summer, as its two main allergens produce cross-reactions with many other plant allergens. Objective. The aim of the study was to evaluate the risk of allergic reactions in persons with pollinosis on the basis of the pollen calendar, analysis of concentrations of pollen grains of grass and rye, and comparison of diurnal pattern of airborne pollen grain concentrations at two sites with different degrees of urbanisation (Gudowo in the country and the city of Szczecin) in 2012–2014. Materials and methods. The concentration of pollen was measured by the volume method. Length of the pollination season was determined by the method of 98%, assuming that the beginning and the end of the pollen season are the days on which 1% and 99% of the annual sum of pollen appeared. Results. The first pollen grains to appear in the air are those produced by rye, followed by those produced by grass and wormwood. The pollen seasons of grasses and wormwood started about one week earlier in Gudowo than in Szczecin, while the pollen season of rye started at almost the same time in the country and in the city. Airborne pollen counts of grasses, rye and wormwood were much higher in the country than in the city. The differences most probably result from the different floristic composition at these two sites and reflect the local contribution of the taxa studied in the country. Conclusions. The risk of allergy caused by the pollen of the taxa analysed was much higher in Gudowo (in the country), than in Szczecin city.

Opis:
The aim of the study was to show epistatic effects of genes responsible for inheritance of important morphological traits in winter rye populations. Furthermore, the thesis that the environment plays very important role in epistatic effects in winter rye populations was verified. The study showed very significant epistasis for inheritance of the important yield components in 1985-1999 years. It was confirmed that epistasis increased or reduced values of the traits under study. It was also showed that epistasis depended on investigated varieties and environments (year of the study). The method described by Comstock and Robinson (1952), and Kearsey and Jinks (1968) consisting in crossing of selected populations with three different testers: T1 (SMH-49), T2 (SMH-75) and T3 (hybrid T1 × T2) was used. The obtained F1 hybrids were sown in 3-replications every year (1985-1999). The epistatic effects were estimated according to formula; Ji = L1i + L2i – 2L3i, where Ji is the epistatic effects of i-th variety, L1i, L2i, 2L3i are the mean values of characters for the hybrids obtained from the crossing between i-th variety and tester. The study concerned following traits: plant height, heading date, length of ear and uppermost internode of ear, grain yield per ear, grain number per ear, 1000-grain yield, grain yield per plot, test weight, falling number, protein content, resistance to brown rust and powdery mildew. Relationships between epistatic effects for selected traits and precipitation and temperature coefficient were evaluated according to Spearman coefficient of correlation.

Opis:
This work is devoted to studying the dynamics of changes in phytotoxicity of oil-contaminated meadow soils in the process of microbial bioremediation. The research was conducted under laboratory and field conditions. Winter rye (Secále cereále) was selected as the test object. In order to assess the degree of toxicity in the laboratory, the indicators of seed germination – germination rate and germination energy-were determined. In a field experiment, the ecological state of oil-contaminated soils was evaluated by the germination rate and the amount of aboveground plant biomass. The research results showed that the content of petroleum products significantly affected the percentage of germination of rye seeds. There are differences in the size of seedlings for different experimental schemes: in all tests, the average height of cleoptila on polluted soil was less than on unpolluted soil, but at the same time it varied for different experimental bioremediation schemes. The use of potassium humate and modified vermiculite as additives significantly reduced the toxicity of the oil-contaminated soil.

Opis:
Head blight caused by Fusarium culmorum or F. graminearum affects all cereals including winter rye (Secale cereale L.). Besides yield and quality losses, grain is contaminated with the mycotoxin deoxynivalenol (DON) that is harmful to animals and humans. We analysed 76 self-fertile S2 lines and their corresponding testcrosses for head blight resistance and DON concentration in the grain by inoculating them with an aggressive isolate of F. culmorum at two locations in Southwestern Germany in 2000. Disease severity at both locations was low with mean ratings from 2.7 to 3.4 on a 1-9 scale (1=healthy), but still DON occurred in considerable amounts (11.4 - 15.0 mg kg-1). Genotypic variance was significant (P=0.01) in all instances, genotype-location interaction and error variances were more important for DON concentration resulting in a lower heritability of this trait. No association between S2 lines and their testcrosses was found for head blight rating or DON concentration (r = 0.33 and 0.19, respectively). The coefficient of correlation between head blight rating and DON concentration was low for the S2 lines and medium for the testcrosses (r=0.24 and 0.60, P=0.05 and P=0.01, resp.). The hybrid rye breeder should select predominantly on testcross performance. Selection for low head blight ratings should result in lower DON concentrations in the grain also. In later generations, DON should be analysed additionally to exploit the maximum selection gain possible.

Opis:
The F2-type population derived from the cross between DS2 and RXL1O inbred lines was used for interval mapping of five growth related traits i.e. plant height, spike length, thousand grain weight, kernel length and kernel thickness. Scanning of the whole 1,140 cM length of rye genetic map consisting of 286 marker loci revealed the existence of 6 regions containing QTL5 on chromosomes 1R-5R. Plant height was strongly affected by 1-3 linked dwarfing genes from a distal region of the chromosome 5RL and by 1 gene on the chromosome 3RL, tightly linked to a marker loci Xpsr4 75. These same genes regulated also thousand grain weight and kernel length and thickness. Spike length was determined only by the QTL from chromosome 5RL. In addition a single QTL from chromosome 2R affecting thousand grain weight and kernel thickness was identified, near the molecular marker locus Xrsq8OS. 1. Kernel length and kernel thickness were additionally controlled by QTL5 on chromosomes 2R and 1R and 4R, respectively.

Opis:
Rye ESTs from public sequence databases proved to be a valuable resource to develop microsatellite markers in rye. One hundred and twenty-one EST-derived Secale cereale microsatellites (SCM) were genetically analyzed in a BC1 population. Fourty-three percent of the studied SCM markers displayed a polymorphism in this mapping population. Linkage analysis in relation to genomic SSR anchor markers as well as AFLP markers allowed to arrange 41 polymorphic EST-derived SCM markers into seven linkage groups which correspond to the seven rye chromosomes. In total, 56 rye SSR markers could be integrated in this second-generation linkage map of rye comprising 685 cM of the rye genome. Distorted segregations with excess of heterozygous progeny were found for most of the markers on chromosome 7R and possible reasons for these are discussed.

Opis:
Economically important rye (Secale cereale L.) cultivars are highly susceptible to leaf rust caused by Puccinia recondita f.sp. secalis in Germany. Presently, only race-specific resistances are available, which are likely to lose their effect after prolonged application. To study possibilities of increasing the durability of resistance, a three-year field experiment was initiated in 2000. Seventeen differential lines, three susceptible standards, 30 segregating populations with one to four resistance sources and two full-sib families were grown at six locations under a high level of natural infection. All segregating populations were significantly more resistant than the susceptible standards. The resistance level, however, was under these conditions moderate only. The two full-sib families from Russia showed high resistance. Strong genotype × location interactions were observed indicating different race compositions of the local leaf rust populations.

Amilo Translocation rye strains created due to distant crossbreeding of cv. Amilo (2n=RR=14) with wild form of Dasypyrum villosum (Crimea, Ukraine) (2n=VV=14) using in vitro cultures were study objects. F2 hybrids were three times back-crossed using parental rye pollen and then twice and three times self-pollinated (B3/F2 and B3/F3), study were sown in a micro-experiment in Laski on a good rye soil complex (ph 6.6) during 1998/1999 (98 strains) and 1999/2000 (123 strains) vegetation seasons. Strains under study were characterized with higher trait differentiation in the first year than the second. They usually headed 4-5 days after standard, although 5 strains among 98 ones studied in the first year and 9 strains among 123 ones in the second headed two days earlier. Comparing to standard, plants height was lower even by 20°cm in both years and their uniformity was usually higher, up to 3.0° and 3.8° respectively. Plant’s lodging was comparable to cv. Amilo at earlier generation; it increased to 1.8° above standard at the following one. Mean 1000-kernel weight of the standard was 36.8 g and 38.7 g, respectively in both years of study; however, it equaled 31.2-47.6 g and 33.8-41.6 g for strains. Only those strains exceeded cv. Amilo referring to protein content (N × 6.25) were selected (0.4-2.6% and 0.1-1.8%, respectively for years of study). Yielding, weight of hectoliter and sedimentation index that were below standard variety should be improved. Generally, better results were obtained in the second year, in which one strain yielded even by 2.8% higher than the standard. Strains selected for further breeding were less infected with black stem rust (up to +1.6°) than a standard rye variety. Selection coefficient amounted 31% and 21%, respectively in the first and second year of study.

Opis:
The paper presents results of studies on the inheritance of plant height in four short-stem genotypes of rye selected from genotypically different collection materials. Short-stem genotypes P-2, P-9, P-30 and P-52 were crossed to a tall-stem inbred line Uniwersalne 145 (S₁₇). The genotype P-2 was additionally crossed to a related, but tall-stem line P-2 W. In each cross combinations six generations - P₁, P₂, F₁, F₂, B₁ (F₁ × P₁) and B₂ (F₁ × P₂) - were examined. Distribution of plant height in hybrid generations had a continuous character, which indicated a polygenic determination of short stem in all "P" genotypes under study. Results of the genetic analysis (degrees of dominance, Burton method, Mather and Cavalli scaling tests, a six-parameter model of inheritance) showed a significant role of additive, dominant and epistatic gene action in genetic determination of short stem in the "P" genotypes. Only in the cross Uniwersalne 145 × P-52 one of the applied methods (a six-parameter model) has not confirmed a significant role of epistasis and dominance. In the cross combinations Uniwersalne 145 × P-2, Uniwersalne 145 × P-9 and Uniwersalne 145 × P-30 a reduction of the plant height was influenced by homozygote × homozygote and homozygote × heterozygote interactions as well as by dominance effects, whereas the plant height increase was influenced by heterozygote × heterozygote interaction as well as by effects of additive gene action. The combination P-2W × P-2 was found to have reverse relationships. The revealed epistasis had a duplicate character. The heritability of plant height was relatively high and varied from 70.4% to 84.9% depending on the cross combination.

The allelopathic potential of classical energy crops (Panicum virgatum L., Sorghum saccharatum (L.) Moench, hybrids 'Zubr' and 'Medovyi') was studied by the energy of germination of biotesters' seeds and their biometric parameters, as well as the selection of sensitive biotesters and test traits. Secale cereale L. and Raphanus sativus L. var. radicula Pers. were used as biotesters. The selectivity of secretions action has been proven – the aqueous extracts from the same energy plant caused different reactions in acceptor plants. The obtained results indirectly indicate the allelopathic potential of energy crops P. virgatum and S. saccharatum. A decrease in the germination energy of the biotester R. sativus var. radicula seeds as well as reduction of underground and aboveground parts of both R. sativus var. radicula and S. cereale were observed under the effect of aqueous extracts of studied energy crops. In order to confirm an allelopathic potential of energy crops, using multiple test signs of different biotesters is suggested.

Opis:
Three hundred twelve inbred lines originated from the hybrid breeding program and two open pollinated cultivars: Zduno and Wibro as a standard were screened for resistance to Micodochium nivale during five years at Radzików. In each year about thirty to hundred inbred lines were evaluated under controlled condition in the cold chamber and parallel in the field. Selected lines were repeated in series of testing in subsequent years. Twenty three lines were tested during three years, sixteen during four years and seven during five years. Significant variation was found for disease rating among investigated inbred lines. Majority of them were severe damaged by M. nivale in all tests. None of tested lines showed an immune reaction to infection. Relative lowest damage were observed in standard cultivars, but a few inbred lines in each test showed the plant loses on the standard cultivars level. Five the best lines selected in 3 year testing confirmed their value in 4 year testing as well. One line which was tested during 5 years showed its high resistance in all series. This results indicate that selection of inbred lines with higher level of resistance to M. nivale is possible by multiyear testing. A positive correlation was found between the disease index of genotypes in cold chamber test and in field test. The coefficients of correlation were much higher in two years of testing than in three other.
