Beschreibung:The first generations of most clone breeding programs do not allow multi-environment trials due to the lack of sufficient reproductive organs. We integrated the phenotypic records of such an early timepoint, called the A clone stage in potato (Solanum tuberosum L.) breeding, into a genomic prediction framework and analyzed (i) if different relationship information can enhance the accuracy of the breeding values from such unreplicated trials, and (ii) whether a weighted combination of these enhanced breeding values with predicted breeding values calculated through genomic prediction can further improve accuracy. Compared to the breeding values derived without considering any relationship information among the clones, enhanced breeding values achieved a higher accuracy for 7–14 traits, depending on the relationship matrix used (multispectral, genetic, pedigree, or a combination). Combining these enhanced breeding values with predicted values from genomic prediction via a heritability index resulted in a weak increase of accuracy (0.5%) for five traits. However, a grid search to find the optimal combination of weights revealed more traits (8–12) with a higher mean increase of accuracy (0.5%–3.8%). Our findings show that the accuracies of unreplicated clones can be increased with easy-to-collect multi-spectral and pedigree data. The magnitude of this accuracy increase was negatively.
