The aim of our investigation was to determine tolerance of some new Lj- maize hybrids to Fusarium subglutinans (FS). Fifty new F1 hybrids were developed by using the scheme of incomplete diallel, and involved 15 inbreds (P1–P10 as female and P12–P16 as male parents). The material was maintained in the maize gene bank of the Biotechnical Faculty in Ljubljana. The field trial was conducted on the experimental station of the Biotechnical Faculty at Jable near Ljubljana in 2011 and 2012. The inoculation by the fungus took place in the middle 5 randomly chosen ears, on each plot, 7-10 days after pollination. The disease assesment was performed during the harvest time according to the ranking scale from 1 to 7. In both years, significant differences in tolerance to FS were determined for hybrids and for general combining ability (GCA) of female lines. Regarding testers (male parents) significant differences in GCA were determined only in 2012, while significant differences for specific combining ability (SCA) were established only in 2011. P10 and P6 (as female parents) and P15 (as a male parent) had the highest value of GCA. The hybrids with the highest value of SCA did not always include the inbreds with the highest value of GCA. However, four out of five hybrids, with the best score of tolerance to FS, include the inbred P15. In our investigation some inbreds showed different response to the existing growing conditions in association with the scored tolerance to FS.

COBISS.SI-ID: 7424889An analytical procedure for the determination of mycotoxins in silage consisting of the extracion of mycotoxins from the samples with an appropriate solvent and the determination with liquid chromatography-tandem mass spectrometry (LC-MS/MS) was presented. The results of the determination of mycotoxins in forty grass and maize silages, sampled at farms in Slovenia were reported.

COBISS.SI-ID: 3601274The results of analyzes, where for the first time the Slovene feed and milk samples contained aflatoxins in the concentrations above limits given in the legislation were presented. For the determination of aflatoxin B1 and M1, the procedures consisting of sample immunoaffinity column clean-up and liquid chromatography were used. 243 milk samples and 53 feed samples were investigated. The maximum level for aflatoxin M1 in consumable milk given in the legislation was exceeded in 23 samples. Among 53 different feed samples analyzed, 20 samples contained aflatoxin B1 in concentrations higher than maximum permitted levels.
