Initial observations point to low fruit production potential. Black fruits tend to mature in mid August (central Iowa). | 1645369 | PI 662003 |
| 1 | PI 649646 | 'Viking' | ×Sorbaronia mitschurinii (A. K. Skvortsov & Maitul.) Sennikov | Finland | NC7 |  | | 2000 | DEVELOPED | 1980 | | | | | Cultivated material | Aronia x mitschurinii is an intergeneric hybrid [(Sorbus aucuparia x Aronia melanocarpa) x Aronia] characterized by more robust stems, wider leaf blades, and larger fruits than wild, native North American A. melanocarpa (Leonard et al. 2013). Majority of Aronia x mitschurinii cultivars used in aronia berry production display indistinguishable phenotypes (Brand et al. 2017). Majority of the research on Aronia fruit polyphenol and anthocyanin content/composition and the health benefits of aronia consumption has been conducted using A. mitschurinii, rather than A. melanocarpa creating a lack of understanding about Aronia taxonomy and genetics (Brand et al. 2017). A. mitschurinii contains more water, less anthocyanins, less phenolics and lower ORACFL values in comparison to many wild Aronia genotypes (Brand et al. 2017). Wild Aronia genotypes may be used directly for commercial fruit production, but they lack the horticultural traits necessary for mechanical harvesting and overall yield. | 1611560 | PI 649646 |

Elliott | Tennessee, United States | NC7 | | | 1990 | COLLECTED | | Marion County | 35.17514700, -85.61147300 | | | Wild material | This accession has been confirmed to represent the "southern form" of A. melanocarpa, potentially a new Aronia species. This southern form was originally discovered by Brand et al. 2022 (Ploidy, genetic diversity and speciation of the genus Aronia) and is known for having glabrous stems and leaves and a distinct phyllotaxy than other Aronia species. In addition, plants tend to bloom approximately two weeks later than all other Aronia taxonomic groups and the inflorescences/infructescences are more spreading and extended due to longer peduncles and pedicels within the cyme. Fruit maturity tends to occur 2 to 4 weeks later than tetraploid A. melanocarpa and 4 to 6 weeks later than diploid A. melanocarpa. Phenolic levels are much higher in comparison to other A. melanocarpa accessions (Brand et al., 2017 - Anthocyanins, total phenolics, ORAC and moisture content of wild and cultivated dark-fruited Aronia species.) | 1061505 | PI 603106 |
