White lupine is a species with a great perspective among annual grain legumes. A biological and breeding evaluation of a collection of 23 white lupine cultivars regarding basic traits and indicators was conducted, with an aim to select suitable parental forms. The study was carried out at the Institute of Forage Crops Pleven, Bulgaria during the period 2014-2016. The cultivars differed in their habitus, duration of the growing season, productivity, biochemical seed composition and susceptibility to Fusarium oxysporum f. sp. lupini. The vegetation period in the Central Northern Bulgaria conditions varied from 129 days in Barde to 148 days in Nahrquell and Shienfield Gard. Dega, Desnyanskii and Barde can be characterized as early-ripening cultivars, and late-ripening ones were Nahrquell, Shienfield Gard and Bezimenii 1. The highest protein content showed Horizont, Bezimenii 2 and Solnechnii (32.7-33.3%), and a reaction of resistance to Fusarium oxysporum f. sp. lupini was demonstrated by nine cultivars (Nahrquell, BGR 6305, WAT, Kijewskij Mutant, Pflugs Ultra, Termis Mestnii, Solnechnii, Pink Mutant, Dega). Particular interest from a breeding viewpoint represents Tel Keram, Termis Mestnii, Solnechnii and Pink Mutant which are distinguished by high values of seed weight per plant and a favourable combination of the other traits, recommending them to be included in breeding programs for development of high-yielding white lupine cultivars.

“…The Virtual Seismological Network of Sofia University was founded in 2015 with a project supported by the Scientific Research Fund of the Sofia University. Until 2021, in the frame of annual projects concerning the Virtual network, data from seismic stations located on the Balkan Peninsula (with free access in near real-time) were used for various scientific studies (Raykova et al, 2018;Dimova et al, 2019;Dragomirov et al, 2021). The access to real-time seismic records has been limited in recent years, mostly to the stations accessible by the European Integrated Data Archive (EIDA).…”

The first seismic station of the Seismic Network of Sofia University (SNSU) was built in 2023 with funding from the Scientific Research Fund of Sofia University “St. Kliment Ohridski”. The station is operating in the Faculty of Physics since September 2023. The equipment consists of a seismometer Geophone 4.5 Hz and a digitiser PSN-ADC24. A portable computer is used for data recording and archiving. During the month of station operation several earthquakes in Bulgaria and neighbouring countries were analysed. The spectrum of the seismic noise from the station was analysed for different periods. The characteristics of the terrain of station installation were also determined using the method H/V. Although the equipment has modest capabilities, it allows students and young scientists to work directly with the seismic equipment and to do scientific investigations. The possibility of scientific research will be expanded renewing the equipment (purchased in October 2023).
