Abstract
This Biosafety Report intends to contribute to ongoing efforts to translate the criteria concerning sustainability, ethical justifiability and social utility in the Norwegian Gene Technology Act into more concrete terms. It does so by presenting ten assessment questions that are important to consider when assessing whether late blight resistant (LBR) genetically modified (GM) potato contributes to sustainability, benefits society and is ethically justifiable in a Norwegian agricultural context. Late blight is the most devastating disease on potatoes globally. Current control measures in conventional potato production are largely based on chemical treatment with fungicides that is costly, both for potato producers and the environment. If successful, cultivating LBR GM potato may result in a reduction of fungicide applications to control the late blight disease in potato production. Hence, LBR GM potato is claimed to be one of the first GM plants that have the potential to solve a serious problem for Norwegian and European farmers.

The effects of postflowering temperature and daylength on the concentration of individual phenolic compounds were studied in black currant (Ribes nigrum L.) berries under controlled phytotron conditions. The four cultivars studied varied greatly in their concentrations of individual phenolic compounds and temperature stability for accumulation. The concentrations of a wide range of identified phenolic compounds were strongly influenced by temperature over the 12–24 °C range, often with opposite temperature gradient patterns for compounds within the same subclass. Accumulation of anthocyanins and flavonols increased under natural long day conditions, which provided an increased daily light integral, while under identical light energy conditions, photoperiod had little or no effect on the concentration of phenolic compounds. Furthermore, with the exception of members of the hydroxycinnamic acid subclass, the concentration of most phenolic compounds was higher in berries ripened outdoors than in the phytotron, apparently due to screening of UV-B radiation by the glass cover.

Triploid apple cultivars are often favored by human selection due to their increased fruit size, even though they possess higher requirements in terms of pollination compared to their diploid counterparts. However, similar to the sensory characteristics, preferences for the size and shape of apple fruit are not universal, but culturally dependent. In order to investigate the influence of selection pressure on the frequency of triploid genotypes among different traditional apple germplasms, 141 apple accessions maintained in ex situ collections in Norway and 115 traditional and international apple accessions from Bosnia and Herzegovina (B&H) were analyzed using 8 microsatellite markers. Genotypes possessing more than two alleles per locus were deemed to be triploid. The results of SSR analyses from this and comparable studies indicate that the triploid apple cultivars are much more frequent among the traditional apple germplasm from Southern Europe than they are among the traditional apple germplasm from Northern Europe. The possible causes for these results are also discussed.
