Selection criteria in cloudberryEivind Uleberg, Inger Martinussen, Gunnlaug Røthe
Clone evaluations at Bioforsk Holt
• Selection criteria– Number of pistils or stamens per flower– Number of flowers– Number of shoots per m2
• Released cultivars– Two female; ‘Fjellgull’ and ‘Fjordgull’– Two male; ‘Apollen’ and ‘Apolto’
Materials and methods
• Clones planted on peat in open outdoor benches– 0.8 m2 squares – 16 plants per square– Established 2003
• Observations– Number of flowers – Number of berries– Fresh weight of berries

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
