Opis:
The resurgence of wheat stripe rust is of great concern for world food security. Owing to resistance breakdown and the appearance of new virulent high-temperature adapted races of Puccinia striiformis f. sp. tritici (Pst), many high yielding commercial varieties in the country lost their yield potential. Searching for new sources of resistance is the best approach to mitigate the problem. Quantitative resistance (partial or adult plant) or durable resistance is reported to be more stable than race specific resistance. In the current perusal, a repertoire of 57 promising wheat lines along with the KLcheck line Morocco, developed through hybridisation and selection of local and international lines with International Maize and Wheat Improvement Center (CIMMYT) origin, were evaluated under natural field conditions at Nuclear Institute for Agriculture and Biology (NIAB) during the 2012−2013 and 2013−2014 time periods. Final rust severity (FRS), the area under the rust progress curve (AURPC), the relative area under the rust progress curve (rAURPC), and the coefficient of infection (CI) were unraveled to infer the level of quantitative resistance. Final rust severity was recorded when the susceptible check exhibited 100% severity. There were 21 lines which were immune (no disease), 16 which were resistant, five moderately resistant, two resistant-to-moderately resistant, one moderately resistant-to-moderately susceptible, 5 moderately susceptible-to-susceptible, one moderately susceptible, and six exhibited a susceptible response. Nevertheless, 51 lines exhibited a high level of partial resistance while the three lines, NW-5- -1212-1, NW-7-30-1, and NW-7-5 all showed a moderate level of partial resistance based on FRS, while 54 lines, on the basis of AURPC and rAURPC, were identified as conferring a high level of partial resistance. Moreover, adult plant resistance was conferred by 47 wheat lines, based on CI value. It was striking that, 13 immune lines among 21 were derived from parents of CIMMYT origin. Cluster analysis was executed to determine the diversity among the wheat genotypes based on stripe rust resistance and yield parameters. All genotypes were grouped into nine clusters exhibiting a high level of diversity at a 25% linkage distance. There were 29 wheat lines resistant to stripe rust that were grouped into the first three clusters, while 4 high-yielding lines were in Cluster VIII. The susceptible check, Morocco, was separated from rest of lines and fell in the last cluster i.e. Cluster IX. Based on the results, inter-crossing immune/ resistant lines is recommended, and with high yielding lines − it is also recommended that cultivars with improved disease resistance and yield potential be developed.

Opis:
The paper is a review of classical and recent studies on willow rusts in Europe, with special reference to short rotation coppice willows used for biomass production, such as common osier willow (Salix viminalis L.). The review presents the taxonomic classification of rust fungi from the genus Melampsora spp. We present a list of telial hosts (genus Salix) as well as aecial hosts for different rust species. The life cycle of this fungal pathogen is described in detail from the epidemiological and genetic point of view. The DNA polymorphism of M. lariciepitea, the rust species most responsible for severe yield losses of plant biomass, is characterised based on RAPD, AFLP and RFLP-PCR methods.

Porównanie pomiędzy językami programowania C oraz Rust na mikrokontrolerach
Comparison between C and Rust programming languages on microcontrollers
Autorzy:
Goworko, Damian
Opis:
W ramach niniejszej pracy przeprowadzone zostało porównanie dwóch języków programowania, C i Rust, w kontekście użyteczności w świecie mikrokontrolerów. W tym celu wykorzystano zestaw do prototypowania STM32F3Discovery i przy pomocy dwóch wspomnianych języków skorzystano z jego możliwości do przetwarzania sygnałów by zaimplementować prosty analizator widma dźwięku. Bazując na tym wykonano porównanie kilku podstawowych metryk programów jak szybkość kompilacji czy też wydajność algorytmu.
This thesis contains a comparison between two programming languages, C and Rust, in the context of their utility in the world of embedded systems. With use of STM32F3Discovery prototyping board and its signal processing capabilities the aformentioned languages were used to implement a simple spectrum analyzer. Using that as basis, a comparison was made between some basic metrics, like compilation time or algorithm performance.

Opis:
The Czech winter wheat cv. Regina which does not possess specific genes for powdery mildew resistance except Pm5 was crossed with the cvs. Florida, Tjelvar, Agra, Olymp and Sabina, all possessing T1BL-1RS and the dominant suppressor SuPm8, with Riebesel 47/51 possessing substitution 1R-1B and SuPm8 and with the T1BL-1RS cvs. Sparta, Iris, Mona without SuPm8. Powdery mildew isolates avirulent on Pm8 and virulent on other Pm genes were used in the trials. Tests for resistance were carried out either on seedlings at the first leaf stage or on detached leaves cultured on benzimidazolagar. No segregation for resistant plants in F₂ of all crosses of the cv. Regina with cultivars possessing T1BL-1RS and SuPm8 indicates that Regina has SuPm8. The segregation ratio 3 resistant: 13 susceptible in the F₂ population of crosses between the cv. Regina and cultivars possessing T1BL-1RS and no SuPm8 also confirms the presence of SuPm8 in the cv. Regina. The obtained results also indicate that expression of Pm2 and Pm4b is not affected by SuPm8 and that SuPm8 does not affect stem rust resistance gene Sr31 located on 1RS segment.

Opis:
A total of 67 barley cultivars and breeding lines were tested for leaf rust resistance were tested with eight differential isolates. These isolates originated from IHAR Radzików collection and were chosen according to their virulence spectra. Among 67 cultivars and breeding lines 41 (61%) showed resistance reaction after inoculation with at least one isolate of leaf rust. In 29 cultivars and breeding lines (43.2%) the presence of specific resistance alleles was postulated.
