Opis:
Introduction: Institute of Natural Fibres and Medicinal Plants (INF&MP) is involved in gathering and evaluation of genetic resources of flax (Linum usitatissimum L.), hemp (Cannabis sativa L.) and medicinal plants, because Poland has signed the Convention on Biological Diversity. Field trials were carried out in 1990–2001 in the Experimental Station in Wojciechów located in Opolskie region. The research material was accessions of genetic resources from the collection of flax, stored at the Institute of Plant Breeding and Acclimatization Institute in Radzików near Warsaw. Objective: The aim of the publication was to evaluate the following biological features of flax: time of beginning of flowering and vegetation period to yellow maturity. Methods: The characteristics data for flax accessions are presented according to the methodology of development of the International Flax Database. Each flax accessions from the world collection of flax genetic resources received one of the following assessments of two vegetation periods: very short, short, medium, long and very long. Descriptors of biological features of flax were used, presented in “List of flax descriptors (L. usitatissimum L.)” edited by Janka Nozkova, published in 2011. These descriptors are used to develop the International Flax Database, which in turn helps in the rapid evaluation of the L. usitatissimum genetic resource collection. Carrying out a detailed characterization of biological features of L. usitatissimum accessions is very helpful for breeders in selecting genetic material for breeding new varieties of flax. Results: The following results were obtained from the time of the beginning of flowering and the vegetation period to yellow maturity. Time of beginning of flowering was the following: very short – 0 accessions, short – 97 accessions, medium – 20 accessions, long – 2 accessions and very long – 0 accessions of flax. The genotypes tested were characterized by the following results in terms of vegetation period from sowing to yellow maturity: very short – 0, short – 37, medium – 62, long – 0 and very long – 0 accessions of flax. Conclusions: Time of beginning of flowering and the vegetation period to yellow maturity shall be revalorised to the International Flax Database for those L. usitatissimum accessions that did not receive the same assessment of the biological features tested in the two or three years of the study.

Opis:
A systematic gathering of winter triticale accessions was started in Poland in 1982 by the Institute of Genetics, Breeding and Seed Science at the Agricultural University in Lublin (at present its name is: Institute of Genetics, Breeding and Plant Biotechnology at the University of Life Sciences in Lublin). First, breeding lines obtained in local breeding stations were gathered. Next, accessions were imported from the following world gene banks: Beltsville, Gatersleben, and VIR. Interesting hybrid materials obtained in research centers were also included in the collection. Now, the collection includes 2349 accessions (1329 of winter triticale and 1020 of spring triticale). The evaluation is conducted in a 4-year cycle of field experiments using the same methods. The gathered accessions represent a large range of variability of both morphological and commercial traits. The large differentiation of accessions especially concerns traits such as: plant height, number and weight of grains per spike, protein content in grain, field resistance to powdery mildew, brown rust and leaf and spike diseases.
Systematyczne gromadzenie materiałów kolekcyjnych pszenżyta ozimego rozpoczęto w Polsce od 1982 roku w Instytucie Genetyki, Hodowli Roślin i Nasiennictwa Akademii Rolniczej w Lublinie (obecny Instytut Genetyki, Hodowli i Biotechnologii Roślin, Uniwersytet Przyrodniczy w Lublinie). Początkowo gromadzono głównie rody hodowlane otrzymane w krajowych ośrodkach hodowli pszenżyta. Następnie sprowadzono materiały ze światowych banków genów: Beltsville, Gatersleben, VIR. Do kolekcji włączono także interesujące materiały mieszańcowe otrzymywane w placówkach badawczych. Obecnie kolekcja liczy 2349 obiektów (1329 pszenżyta ozimego i 1020 pszenżyta jarego). Ewaluacja prowadzona jest w 4-letnim cyklu doświadczeń polowych według jednolitej metodyki. Zgromadzone materiały kolekcyjne reprezentują duże spektrum zmienności zarówno cech morfologicznych, jak i użytkowych. Duże zróżnicowanie badanych obiektów kolekcyjnych dotyczy zwłaszcza takich cech, jak: wysokość roślin, liczba i masa ziarn z kłosa, zawartość białka w ziarnie oraz polowa odporność na mączniaka właściwego, rdzę brunatną oraz choroby liści i kłosów.

Opis:
W artykule opisano system szeregowania zadań niepodzielnych na jednej maszynie. System pozwala zoptymalizować plan produkcji poprzez ograniczenie ilości operacji transportowych i pomocniczych oraz poprzez poszukiwanie takiej kolejności realizacji zadań, dla której łączny czas wykonania będzie możliwie najmniejszy. Zastosowano zmodyfikowany algorytm genetyczny pozwalający na częściowe dostrojenie procesu do struktury danych. Testy przeprowadzone zarówno na danych dostępnych publicznie, jak i na danych pochodzących ze środowiska wytwórczego udowodniły skuteczność przyjętych rozwiązań.
A system for scheduling indivisible tasks on a single, periodically accessible machine is presented in this paper. Because of the constrains existing in the environment, the scheduling problem presented here is similar to the one-dimensional bin-packing. The tasks, stacked on a palettes (Fig.1), were transported to the machine. The palette caould be replaced by another one only after completing all the tasks assigned to it. Each task was defined by an execution time Tz and an auxiliary time Tp. The transportation time To was added to the last task from each palette and to the last task executed within the machine availability period Tm (Fig.2). A modified genetic algorithm was used for the scheduling, where the parameter K defined the number of gene changeovers (representing changing the sequence of palettes and changing the sequence of tasks within a palette) during one mutation. The results obtained for the data available in public [13] and in selected publications are presented in Tab.1. It was noted that the distribution of scheduling results (fitness=Cmax) could be modified by changing the parameter K (Figs.4 and 6). The observation was proved statistically for the data from the manufacturing system by means of the median test run for the set of 500 results, 50 for each K=1..10 (χ2=19, df=9, p=0,0254<0,05). The results of the test proved that the scheduling algorithm could be tuned for speed by adjusting the value of K. Assuming that the process was random, it could be calculated that for K=5 the expected time of getting the solution Cmax<2050, expressed in the number of generations, was the shortest (assumed confidence level 0.99). The scheduling system allowed the definition of individual machine availability periods and taking into account the restrictions of the transport system (the allowed sequences of palette retrieval).

Opis:
The article reviews the work of the author and coworkers on the use of electrophoretic protein analysis in taxonomie studies and classification of genetic resources of some leguminous plants: the genus Pisum, the Old-World Lupinus species and the cultivated Phaseolus species. On the example of the genus Pisum, the object of many years' investigations, the usefulness of electrophoretic analysis of different protein types - seed globulins, seed albumins and enzyme systems - is critically discussed. It has been concluded that variation in seed albumins, proteins often ignored in comparative analyses, should be more widely considered in taxonomie investigations. The conclusion was supported by the results obtained for Lupinus and Phaseolus species.

Opis:
The work outlines the directions in the past and present research into the variability of Norway spruce in Poland, and presents the results of provenance experiments concerning the genetic and breeding value of provenances tested in the Polish range of spruce distribution. The Istebna race proved to have a good value, however, so far only the progeny of single stands have been tested. It is thus necessary to determine the range of distribution for this race. The altitude of the location of mother stands significantly correlates with the genetic and breeding value of their progeny cultivated at different altitudes. This suggests that the altitude and exposure of plantations to be established in mountain forest belts should be specified for individual provenances (altitudinal zoning). New inventory provenance tests should be run under varied site conditions to assess both the genetic value and plasticity range of the provenances. In view of the biotic and abiotic threats facing spruce, there is a need to work out detailed programmes designed to preserve its genetic resources in gene banks and in vivo archives.

Opis:
The Sauerland region of southern Westphalia has the most economic stands of Norway spruce in the state of Northrhine-Westphalia (Germany). As shown by historical research and genetic analysis, the seeds for these stands were imported from Thuringia around the year 1880. Therefore, the two states are collaborating closely to secure the genetic variety of the spruce and develop new sources of seed supply. The survival of the Hochsauerland Norway spruce is now under threat: these stands have already been harvested or are due for harvesting shortly, in addition, many of the older stands were destroyed by the gale "Kyrill" in 2007, and only a few stands have remained. Since its foundation, the Forest Gene Bank of Northrhine-Westphalia has taken the following measures to preserve the gene pool of the Hochsauerland spruce and conserve it in the long term: storage of seed from 100 representative trees in all the most valuable stands of spruce (since 1985); establishment of seed orchards; and establishment of replacement stands. Thanks to those measures, the genetic information of the Norway spruce stands of Thuringian origin has been secured, and substantial stocks of seed are available for reforestation.

Introduction: In 2020, the Institute of Natural Fibres and Medicinal Plants (INF&MP) implemented the contract No. 7/PW 1.2 – IWNiRZ Poznań/KCRZG/2020 for the performance of a research service under the long-term programme “Creating scientific foundations for biological progress and protection of plant genetic resources as a source of innovation and support for sustainable agriculture and safety food for country”. Objective: The aim of the research was to prepare passport and valorisation data for 33 accessions of flax (Linum usitatissimum L.) sown at the INF&MP Experimental Station in Pętkowo. Methods: The field experiment was conducted on 33 samples of flax seeds, which were sown on an area of 1.6 m2. Morphological features were presented by means of numerical data and their evaluation. The agricultural characteristics (numerical values and percentage of the collective pattern) and lengths of vegetation period were also presented. The evaluation of the performed characteristics of flax accessions was presented numerically and the data were given to the International Flax Database. Results: On the basis of paper documentation, the country of origin of the accessions, the type of genotypes by origin (landrace, variety) and the date of inclusion of the accessions in the flax collection were determined. The results of the characterization of morphological trials were as follows: the total plant length of the flax plants ranged from 51.4 cm (La Estanzuella 117) to 76.5 cm (WUKR 06-417) According to the methodology of the International Flax Database, the total plant length were short (28 accessions), medium short (3) and medium (1). Technical length was usually short (28 accessions) and medium short (4 accessions). Stem thickness for all accessions was medium: 1.6–2.5 mm. The length of the panicle was long only for the Opal variety, for 25 accessions - medium and short for 6 accessions. A number of bolls from panicle was: 9.1–30.8. The 1000 seed weight was low for 25 accessions of flax and very low for 8 genotypes of flax. Conclusions: Both studied vegetation periods were short in the following flax accessions: AC Linora, Manchwrian, Noralta and T-397. Flax genotype WUKR-846 (I2010/0031) should be deleted from the flax genetic resources collection and considered as worthless as breeding material. The WUKR 06-417 accession collected during the field expedition is distinguished by a high fibre content – 27%. The highest seed yield per plot was obtained from the cultivation of the following linseed flax cultivars: Redwood, AC Mc Duff, Norlin, Noralta and Jenny.

Opis:
The optimal use of resources available in the enterprise is important regardless of the size of the company and the industry in which it operates. Enterprises are therefore forced constantly to make alternative choices related to the allocation of available resources and to optimize these choices. The article addresses the problem of the approach to optimizing the use of human resources particularly, the use of extra employee qualifications e.g., manual skills, pressure resistance, work precision, the ability to read schematic diagrams, etc. in the context of technical requirements for a given task. This is extremely important in the situation when subsequent works are individual and the conditions in which they will be performed, cannot be predicted in 100%, they may differ from those that have been implemented so far, and at the same time numerous orders of various nature are being implemented. In this situation, an accurate prediction of the requirements posed by new tasks and the appropriate selection of teams executing them can have an impact on the effectiveness of the task completion process. In the article, this problem is presented on the example of a medium-sized service enterprise operating in the industry-related sector operating basically on tender procedures and tender contests. The works are carried out on the customer's premises, often with new customers or in new field conditions. Thus, the success of the undertaking depends mainly on the optimal selection of employees with appropriate qualifications and competences. The example of an investment task is used to show a method of identifying characteristics relevant to the task as well as selection of employees in order to use the capabilities of human teams better. Technical aspects of task implementation and an employees team selection with regard to the absolutely required technical qualifications as well as the behavioral and physical skills necessary for its implementation are taken into account. The described method can be used for future tasks regardless of the changing conditions of their implementation. The intention of the authors is to develop a tool supporting the decision-making process in this area, so that it can also be used by managers with lower technical competences.

Opis:
The wild-harvested fruit of Vaccinium oxycoccos (European cranberry) is used medicinally in many European and North American countries; the plant, however, is seldom cultivated. In order to optimize the collection strategy and improve the horticulturally important characters of V. oxycoccos clones, comprehensive investigations of the species are necessary. In the present study we investigated the phenological, morphological and genetic diversity of 29 clones originating from two wild populations growing in two strictly protected Lithuanian reserves, Čepkeliai and Žuvintas. During an ex situ collection at Kaunas Botanical Garden, we observed great phenological variation between the collected V. oxycoccos clones. The following morphological traits most clearly distinguished our study clones: leaf size, berry shape, berry size and fruit colour at full maturity. The genetic variation of V. oxycoccos clones from the two populations was assessed using RAPD and SSR. RAPD analysis conducted with 9 primers resulted in 146 polymorphic loci for the total sample, and SSR analysis with 5 primers revealed 29 alleles for the total sample. A greater degree of polymorphism was demonstrated for the Čepkeliai population than for the Žuvintas population. The study allowed the selection of several clones having promising morphological traits for further testing in the field.

Opis:
This paper deals with the problem of preemptive scheduling in a two-stage flowshop with parallel unrelated machines and additional renewable resources. The objective is the minimization of makespan. The problem is NP-hard. Heuristic algorithms are proposed which join the linear programming based procedures with metaheuristic algorithms: genetic, simulated annealing and tabu search algorithm. The performance of the proposed algorithms is experimentally evaluated by comparing the solutions with a lower bound on the optimal makespan. Results of a computational experiment show that these algorithms are able to produce good solutions in short computation time and that the metaheuristics significantly improve the results for the most difficult problems.
