Correct and rich professional and scientific terminology is an important contribution to the development and richness of the national languages. Within the scientific and professional terminology, we can often find incorrect or misinterpreted use of professional terms. An example of such embarrassments in Slovenian language is the use of the words 'tla', 'zemlja' and 'prst'. Terminological dispute can be considered as peripheral theme, however it has more important dimension. Namely, the Slovenian versions of some EU legal documents are semantically ambiguous and inadequate and, thus do not reflect the correct meaning of source texts due to inappropriate translations. The paper presents and arguments the reasons for use of selected basic soil science terms in Slovenian language. Additionally, it recalls the etymology of the popular terms 'prst', 'tla' and 'zemlja', compares the situation in number of European languages and suggests the appropriate use of terms in professional/scientific language and for translation purposes.

Association between polymorphisms on PRKAG3 (Ile199Val) and CAST (Lys249Arg and Ser638Arg) genes and dry ham seasoning losses was studied. A total of 724 green hams (same pig crossbreed, same pig producer) were selected, genotyped (PCR-RFLP) and processed according to the rules of consortium for dry-cured ham Kraški pršut. Weight losses after each processing phase were recorded. We observed significant effect of interaction between gene polymorphism and dry ham producer on seasoning losses, indicating that the effect of studied genes differ in relation to manufacturing practice or product type, despite narrow consortium constraints. The analysis was thus made separately for each producer; in case of producer B, PRKAG3 affected salting, resting and overall losses (Val/Val higher than Ile/Ile or Ile/Val) but in case of producer A, the effect of PRKAG3 was significant only for salting losses (Ile/Val lower than Ile/Ile or Val/Val). Effects of CAST polymorphisms were significant only in case of producer A; CAST249 Arg/Arg hams showed the highest first salting, drying, and overall seasoning losses, whereas CAST638 Arg/Arg hams had the highest drying, ripening, and overall seasoning losses. In conclusion, PRKAG3 and CAST polymorphisms were associated with seasoning losses, important from economic viewpoint, but also for salt intake and product quality. © 2011 Licensee PAGEPress, Italy.

Heterosis is commonly associated with the superiority of the first filial generation over the parental generation. From the economic point of view it is important that the superiority could be expressed as a higher productive potential of the variety. Given the slow growth of the average grain yield of common wheat (Triticum aestivum L.) at global and national level, the use of hybrids for production of this economically important crop, is gaining the importance. The most important condition for hybrid seed production in common wheat is cross-pollination that can be achieved by induction of male sterility. In the past, different approaches for induction of male sterility in common wheat have been proposed, for example the use of cytoplasmic male sterility (CMS system) transferred from Triticum timopheevi Zhuk. Due to its complexity, the genetic approaches have never been exercised in the practice. Today the chemical hybridizing agents allow development of hybrid varieties that can top the yield of standard inbred varieties for more than twenty percent. Transgenic approaches represent the alternative to the chemical induction of male sterility. Hybrid wheat seed production is therefore technologically complex process that depends on the level of heterosis, hybrid seed yield per area unit and the market price of wheat.

Prediction of the expected milk yield is important for the management of the primiparous cows (PPC) with a few or no data on their own milk productivity. We developed a system of regression equations for predicting milk yields in standard lactation. The models include the systematic effects of the calving season, the five-year rolling herd average of milk yield of PPC, the breeding values of the parents for milk production, and daily milk recordings. A total of 21,901 lactations of Holstein PPC were collected during the regular monthly milk recordings of cows in the Republic of Slovenia. By including daily milk recordings in the model, the coefficients of determination of regression models for the prediction of milk yield increase: without known recordings (M0) R2=0.80; with one recording (M1) R2=0.82; with two first consecutive recordings (M2) R2=0.86; and with three recordings (M3) R2=0.89. Deviations of milk yield up to 500 kg in a standard lactation (<1.6 kg/day) were as follows: with the model M0, they occurred in 53.4% of PPC; with M1, they occurred in 56.3% of PPC; with M2, they occurred in 64.5% of PPC; and with M3, they occurred in 70.9% of PPC. We concluded that the developed system of regression models is an appropriate method for milk yield prediction of PPC. © J. Jeretina et al., 2015.

The history of potato breeding and gene bank in Slovenia is described. First variety trials were organized in 1895 in Ljubljansko barje, followed by variety garden in Bokalce after 1935. Breeding of new potato varieties started at Kmetisjski inštitut Slovenije in 1949 and 15 varieties had been released until 1999. 9 new potato varieties resistant to PVY has been developed in a new breeding programme after 1993. At Kmetijski inštitut Slovenije slovenian potato varieties are maintained as in vitro plantlets in tissue culture lab, as micro tubers, and as plants in screenhouse and in the field: 'Igor', 'Cvetnik', 'Dobrin', 'Jubilej', 'Karmin', 'Vesna', 'Matjaž', 'Jana', 'Jaka', 'Meta', 'Tone', 'Kresnik', 'Cita', 'Pšata', 'Bistra', 'KIS Mirna', 'KIS Sora', 'KIS Sotla', 'KIS Kokra', 'KIS Mura', 'KIS Vipava' and 'KIS Krka'. Variety identity is checked by microsatelite markers.


Anthracnose is one of the most important fungal diseases of cultivated blueberries. It mainly affects fruits and causes rotting of ripe fruit both before harvest and during storage. Infected blueberries become wrinkled, soft and covered with slimy orange conidial masses. In the years 2005 -2009 we collected 33 samples of symptomatic plants from high-bush blueberry plantations in the Ljubljana Wetland. Using standard morphological and molecular methods we identified Colletotrichum fioriniae as the causative agent of the disease. Successive isolations from naturally infected high-bush blueberry bushes revealed the presence of C. fioriniae during the entire growing season. It was consistently isolated from symptomatic as well as from symptomless tissues. We confirmed that the fungus overwinters in canes with dead tips and fruit spurs and also in symptomless canes and buds. Buds, particularly flower buds, appear to be the most important source of primary inoculum apart from canes with dead twigs and fruits spurs.


In Slovenia Carniolan honeybee (Apis mellifera carnica Pollman 1879) is an autochthonous and protected honeybee subspecies. Based on morphological characteristics A. m. carnica belongs to the southeast European group of honeybees and is the second most widely spread honeybee subspecies in the world. Slovenia is the origin country of A. m. carnica and its conservation is stipulated by law In the last few years more honeybees with yellow bands on the abdomen were seen in the population of A. m. carnica in Slovenia. These characteristics are the result of hybridization with other honeybee subspecies. Apis m. carnica is nowadays to a large extent influenced by beekeeping activities (trade with bee colonies and queens, migratory beekeeping) and also natural conditions and hybridization in the zones of natural hybridization. To find out the percentage of hybrid honeybees in the population of A. m. carnica in Slovenia, a morphological investigation based on the colour of bands on the worker abdomen was made. We found the highest percentages of honeybees with yellow bands in the West part of Slovenia near the border with Italia (Obalno Kraška and Goriška region) but also in the Koroška region. On average 5.6% honeybees in the population of A. m. carnica in Slovenia have yellow bands. Further hybridization of A. m. carnica with other honeybee subspecies could led to loss of morphological, ethological and genetic characteristics of A. m. carnica population in Slovenia.

Drought stress is a serious threat to crop production that influences plant growth and development and subsequently causes reduced quantity and quality of the yield. Plant stress induces changes in cell metabolism, which includes differential expression of proteins. Proteomics offer a powerful approach to analyse proteins involved in drought stress response of plants. Analyses of changes in protein abundance of legumes under drought stress are very important, as legumes play an important role in human and animal diet and are often exposed to drought. The presented results of proteomic studies of selected legumes enable better understanding of molecular mechanisms of drought stress response. The study of drought stress response of plants with proteomic approach may contribute to the development of potential drought-response markers and to the development of drought-tolerant cultivars of different legume crop species.
