    Nineteen microsatellite markers were used to fingerprint a set of 19 potato landraces from the island of La Palma (Canary Islands). These landraces represent relicts of early introductions from South America, although most are commonly cultivated by local farmers. The SSR primers detected 62 polymorphisms, 13 of which were present in all landraces. Several accession- and group-specific markers were detected. Jaccard similarity coefficients were estimated from the molecular data and UPGMA cluster analysis was performed. Some cultivars with related common names clustered together.

    The effects of subsidies on the development of organic farming (OF) in the Czech Republic and in some selected EU countries are analysed in this article. The level of subsidies for OF in the Czech Republic is continuously increasing. In 1998, the total amount of subsidies was 48 million CZK, whereas in 2004, it increased to nearly 277 million CZK. The increase of subsidies led to an increase in the number of organic farms as well as the area under OF.

    This study was done to establish relationships between management and sanitary practices on ewe dairy farms and the quality of milk produced. For this purpose, a survey was carried out on 118 farms and a total of 121,117 animals in the Castilla-La Mancha region (Southeast Spain) in which the veterinarians of the Association of Sanitary Defence participated. Flocks varied considerably in size, ranging from 120-7,200 sheep, with an average milking period lasting 3-5 months and milk yields of between 50 and 150 litres per lactation by mechanical systems on 75.0% of farms.

    In Slovenia, the Natura 2000 network covers 35.5% of its territory or 286 areas, encompassing 10 forest habitat types. The majority of indicators for the assessment of the conservation status and changes of forest habitat types are to be estimated within the forest management planning framework. In this paper, a hierarchical concept of forest habitat types monitoring in Pohorje Mts (810 km2) was examined and presented, based on landscape structure and position of habitat types in this structure.

    El artículo presenta los resultados obtenidos en los distintos proyectos llevados a cabo por la Universidad de Murcia (caracterización genética de la abeja murciana y protección y mejora de las poblaciones locales, análisis de la diversidad genética de poblaciones peninsulares e insulares de Apis mellifera iberiensis, entre otros), que les ha llevado a caracterizar las poblaciones de abejas de la Península Ibérica y a trazar un mapa de distribución de linajes evolutivos de estas poblaciones.

    Semen was collected from 10 Black Castellana roosters and the classic sperm variables (ejaculate volume, sperm concentration and sperm motility) examined. In addition, the hypo-osmotic swelling test was used to investigate sperm cell membrane integrity, and acidic aniline blue staining used to screen for morphological abnormalities (including acrosome integrity) and to examine the condensation status of the chromatin. The latter was also examined by Gram staining. Large and small semen volumes were associated high and low sperm concentrations respectively (R2=0.04, P>0.05).

    La importancia de los incendios forestales en la cuenca mediterránea hace de estas perturbaciones un factor determinante en el análisis y la gestión de riesgos ecológicos, así como en los vinculados a la protección civil. La actual demanda de servicios recreativos en el bosque genera una intensificación de estos riesgos, lo que precisa de una adecuada respuesta por todos los agentes implicados en la gestión.

    Among the species, that are collectively called rocket, only three species of genus Diplotaxis (D. tenuifolia, D. muralis and D. viminea), can be found growing wild in Slovenia while species from the genus Eruca are not occurring. The Gene Bank of Agricultural Plants at the Agricultural Institute of Slovenia holds 19 autochthonous accessions from different parts of Slovenia. The main morphologic

    Cabbage production in Slovenia has a long tradition. Domestic varieties are bred from autochthonous population from different parts of Slovenia. The characteristics of domestic varieties (e.g. for sauering) are important for Slovenian consumers. On the other hand hybrid cultivars are uniform, give much higher yields and they are resistant to different diseases. So far, cabbage breeding at the Agri

    Numerous autochthonous varieties have been developed during centuries of lettuce (Lactuca sativa L.) cultivation in Slovenia. In the Slovene Plant Gene bank (SPGB), maintained at the Agricultural Institute of Slovenia, 177 accessions are included that were obtained from various parts of Slovenia in the nineties of the last century. In addition, wild relatives and accessions obtained for the resear
