Fruit quality is a major determinant of commercial success in raspberry cultivars. Yet the established ways of measuring quality: chromatography and trained sensory panels, are slow, costly and, for sensory work, variable. Raman spectroscopy is a rapid, reagent-free alternative based directly on molecular vibrations, and is now available in handheld form. Nine raspberry cultivars and two breeding selections were grown in an open polytunnel at NIBIO Apelsvoll, Norway, in 2023, and berries were sampled early and a late in the harvest season. Spectra were recorded with an 830 nm handheld instrument from intact berries and from pressed, centrifuged juice and related to HPLC analyses and sensory panel taste scores. Empirical multivariate models based on partial least squares regression, applied to pre-processed spectra of raspberry juice samples, showed promising potential for estimating total sugars (R2cv = 0.96, RMSECV = 3.4 g L-1), the sugar/acid ratio (R2cv = 0.96) and citric acid (R2cv = 0.94), and moderate potential for the sensory taste score (R2cv = 0.55 on a 1-9 scale). Regression coefficients and VIP scores placed the models on sugar bands near 1065, 1085 and 1128 cm-1 and on citrate bands near 940 and 1720 cm-1, matching published assignments. A calibration-free two-band ratio, I(1115-1145)/I(925-960), tracked the sugar/acid ratio almost as well as the full model (r = 0.945). Measurements of intact berries could not be used for estimating any property (R2cv <= 0.36); the relative standard error of the sugar band was 7.0-9.3% per scan against 1.9% for juice, identifying drupelet heterogeneity rather than absent signal as the obstacle. Handheld Raman spectroscopy shows promising potential as a rapid screening tool for extracted raspberry juice, however for measurement of the intact fruit further method development is needed.

Dette notatet gir en oppdatering av kunnskapsgrunnlaget og relevans for klimatilpasning for de mest sentrale planteproduksjonene, dvs. korn, grovfor, grønnsaker og potet, frukt og bær. Notatet tar utgangspunkt i teksten i ulike fagnotater fra 2016, og oppdaterer beskrivelsene med oppdatert kunnskap relevant for de ulike produksjonene. Økt gjennomsnittstemperatur, økt CO2-konsentrasjon i atmosfæren og en lengre vekstsesong er fordeler som vil kunne utnyttes. På den annen side vil økt nedbør og mer ekstremvær i fremtiden bli utfordringer som må håndteres. Notatet peker på både utfordringer, muligheter og kunnskapsbehov for å lykkes i klimatilpasningsarbeidet.

We present a harmonized database of national variety trials and official Value for Cultivation and Use (VCU) trials from the five Nordic countries, Denmark, Norway, Sweden, Iceland, and Finland, focusing on three key crops for that region: spring barley (Hordeum vulgare), red clover (Trifolium pratense), and potato (Solanum tuberosum). Yield is the primary phenotypic trait reported. The location of each trial is also reported, which enables analysis of how weather variability impacts crop performance. Climate change will have a substantial impact on agriculture, requiring the development of new crop cultivars adapted for resilience to future stresses. Developing a new crop cultivar is a decades-long process, therefore climate change considerations must already be incorporated into breeding programs. National breeding programs have typically involved field trials in a single country, which has functioned satisfactorily during periods of stable climate variability. However, it is widely acknowledged that when field trial information across borders is made available, it can significantly aid plant breeding programs. Here, we present a pan-Nordic multi-environment database that consolidates national trial data and data from VCU trials for spring barley, red clover, and potato. The database harmonizes information on yield across diverse environments, enabling comparative analyses and cross-regional assessments. By providing a unified resource for the Nordic region, this dataset supports the development of more resilient crop varieties and facilitates data-driven breeding strategies under changing climatic conditions.

The poster summarizes multi-year field trials on sweet potato production under Nordic conditions, conducted at Landvik, Norway. It presents the background for testing sweet potato as a high-value crop in Norway, including increasing demand, full reliance on imports, and the limitations imposed by a short growing season. The objective was to evaluate season-extension strategies, including mulch, low tunnels and fiber-cloth coverage, and to identify high-performing cultivars. The poster includes a trial overview, materials and methods, selected results for cultivar performance, mulch and tunnel treatments, and earlier trials with different numbers of fiber-cloth layers. It also includes field-trial photos, selected references and conclusions on the agronomic potential and limitations of sweet potato production in Nordic conditions.
