    Opis:
    Native breeds of sheep in the Polish Carpathians (Polish Mountain Sheep, Podhale Zackel, Coloured Mountain Sheep) are very well adapted to the local environmental conditions, undemanding in feed and highly resistant to adverse living conditions. They play an important role in rural tourism as a component of landscape, folk culture and supplier of many valuable products. To save local breeds from extinction and preserve valuable characteristics in the population they were included in the sheep genetic resources conservation program, while the national agri-environmental program provides breeders with financial support. Podhale Zackels accompanied man during the period when the wild Carpathian areas were being settled and became a permanent feature of the highlander economy and culture. Coloured Mountain Sheep were kept by mountaineers due to the dark hue of their wool and skin, used to produce regional dresses and decorative elements. Mountain breeds are a multipurpose sheep. They give milk for production of traditional products (oscypek, bundz, bryndza, redykolka, żentyca), wool and delicious meat. Podhale Lamb, derived from mountain sheep, gained the status of Protected Geographical Indication.

    Opis:
    Celem rozważań jest odpowiedź na pytanie, czy przyjęte na poziomie unijnym normy prawne w zakresie hodowli zwierząt gospodarskich służą jej właściwej organizacji oraz czy ustawodawca krajowy przewidział odpowiednie rozwiązania pozwalające na wykonywanie prawa Unii Europejskiej. Według autorek nastąpiło przekształcenie i pewne uproszczenie europejskiego prawodawstwa zootechnicznego, pozwalające na płynne i efektywne prowadzenie działalności hodowcom. Przyjęcie w kraju nowej ustawy o organizacji hodowli i rozrodzie zwierząt gospodarskich pozwala na pełne i prawidłowe wykonywanie rozporządzenia unijnego, a także zapewnienie trwałości prowadzenia hodowli zwierząt gospodarskich dzięki ciągłości prowadzenia ksiąg hodowlanych i rejestrów oraz prowadzenia oceny wartości użytkowej i genetycznej zwierząt.
    The purpose of the considerations was to answer the question whether the legal standards governing livestock farming adopted at the EU level serve the purpose of proper organisation of animal husbandry and whether the Polish legislator has ensured appropriate solutions enabling proper implementation of European Union law. The conclusions of the considerations are that European Zootechnical Legislation has been simplified, allowing for a smooth and effective conduct of livestock farming. The new Act on the organisation of breeding and reproduction of farm animals enables full and correct implementation of the EU regulation in Poland. At the same time, the requirement arising from the Act to conduct assessments of the utility and genetic value of animals and to maintain herd books and records guarantee the durability of livestock farming.
    L’articolo si propone di stabilire se le norme giuridiche, adottate a livello dell’UE in materia di allevamento del bestiame, aiutino a gestire l’allevamento in modo giusto, nonché se il legislatore nazionale abbia previsto soluzioni adeguate al fine di applicare il diritto dell’UE in modo corretto. Nella parte conclusiva, le autrici affermano che la legislazione zootecnica è stata semplificata, il che permette di svolgere l’attività di allevamento senza difficoltà e in modo efficace. L'adozione di una nuova legge, volta a disciplinare l'organizzazione dell'allevamento e la riproduzione del bestiame, consentirebbe l’attuazione della normativa dell’UE in modo pieno e corretto. Allo stesso tempo, assicurando la continuità della tenuta dei libri genealogici e dei registri, nonché effettuando la valutazione delle prestazioni e del valore genetico del bestiame, la durabilità dell'allevamento sarebbe garantita.

    Opis:
    Wych elm (Ulmus glabra Huds.) is a rare scattered forest tree species in Poland. First studies on genetic diversity of the species in its natural range in Poland give a good basis for the management and conservation of its genetic resources. In the present study, we determined the level of genetic variation and genetic differentiation of seventeen natural Wych elm populations in Poland using nine nuclear microsatellite loci. The number of analyzed individuals was 601. The level of genetic diversity of Polish populations of Wych elm corresponded with the results of the previous studies on this species in Europe. The populations show quite low level of genetic diversity of the species on the population level and quite high diversity on the interpopulation level. A total of 119 alleles was found, with average number per locus (A) equal 6.0 and allelic richness at medium high level (AR10=4.7). Observed (Ho) and expected (He) heterozygosity reached 0.583 and 0.602 respectively. The genetic differentiation between Polish populations of Wych elm occurred at a low level (Fst=0.089). Inbreeding depression may occur in the next generations (Fis=0.031). Genetic diversity between Wych elm populations in Poland may be the result of unfavorable random processes related to the reduction of population size resulting from elm disease. To better understand the processes related to the genetic diversity of Wych elm populations, research on field elm variation should be undertaken. Such studies may give an answer to the potential influence of introgression between these species on the genetic structure of the Wych elm. Both in situ as well as ex situ conservation measures are highly recommended to preserve genetic resources of this valuable noble hardwood species in Polish landscape.

    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.

    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.
