1. Selection criteria in cloudberry Eivind Uleberg, Inger Martinussen, Gunnlaug Røthe

2. Clone evaluations at Bioforsk Holt Selection criteria – Number of pistils or stamens per flower – Number of flowers – Number of shoots per m 2 Released cultivars – Two female; ‘Fjellgull’ and ‘Fjordgull’ – Two male; ‘Apollen’ and ‘Apolto’

3. Materials and methods Clones planted on peat in open outdoor benches – 0.8 m 2 squares – 16 plants per square – Established 2003 Observations – Number of flowers – Number of berries – Fresh weight of berries

9. Mean berry weights as affected by harvesting time

10. Antioxidant content of different genotypes

11. Conclusions Further evaluations needed before deciding future selection criteria – Genetic and environmental variance – Heritability estimates – Genotype by environment interactions? Berry contents will most likely be included as new selection criteria
