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 |

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 |

Sennikov | Former, Soviet Union | NC7 |  | | 1967 | COLLECTED | | | | | | Cultivar | Medium-sized shrub, potentially reaching 15-20 feet in height. White flowers form in the spring and are pollinated by bees. Leaves are a deep glossy green. Fruit begins to form pendulous clusters in mid to late summer, turning a purplish-black color by September. Berries are about 0.5 inch or less in diameter and contain one to five very small seeds; quite juicy, but begin to shrivel after ripening. Juice and seeds are a deep purple in color. Berries generally persist and are not readily used by most bird species until end of winter. Can be used in wildlife plantings and as a shrub row in farmstead or other multiple row plantings. The short stature fits well under overhead irrigation systems. It is attractive in landscape plantings. 'McKenzie' is a intergeneric hybrid involving Aronia melanocarpa and Sorbus acuparia backcrossed to Aronia melanocarpa. Hardy to Zone 3. Performs best on well-drained to moderately well-drained sites with combinations of silty or loamy textured soils. Released in 2008 by the Natural Resources Conservation Service Bismarck Plant Materials Center, Bismarck, ND due to its superior performance for more than 25 years. | 1240617 | PI 323957 |
