| 2 | PI 603106 | Index Seminum 8 | Aronia melanocarpa (Michx.) 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 |

Fruit are distinctively teardrop shaped rather than round. Genetics of this diploid accession (Ames 33737: UC 012) was used as the female parent in the development of 'UCONNAM165' Low Scape Mound® Chokeberry (US Plant Patent 28789). | 1942823 | Ames 33737 |

Elliott | Maine, United States | NC7 |  | | 2016 | COLLECTED | PRE 08/01/2007 | Collected from three areas of Lincoln and Knox Counties (one plant from each site). | 44.03833330, -69.09527780 | | Waters edge on rocky head (Ames 33737: UC012); woodland edge near boat dock (Ames 36065: UC017); rocky bald on Mt. Battie (Ames 36066: UC020). | Wild material | This accession represents genetics sampled from three areas originally collected as Ames 33737, Ames 36065, and Ames 36066. These three diploid clonal accessions were combined in order to execute a successful seed increase requiring cross pollination by other diploid genotypes. Phenotypes range from ground cover types to open spreading shrub types. Two of these clonal collections (Ames 33737: UC 012 and Ames 36065: UC 017) were parents in the development of 'UCONNAM165' Low Scape Mound® Chokeberry (US Plant Patent 28789). | 2141932 | Ames 36069 |

| 7 | Ames 33073 | 'Professor Ed' | Aronia melanocarpa (Michx.) Elliott | New Hampshire, United States | NC7 |  | | 2015 | COLLECTED | 2008 | | | | | Cultivar | Clonal selection. Originally collected from the wild by Isaac Langley Williams, native plant collector of Exeter, New Hampshire in 1956. In 2008, it was named 'Professor Ed' by Roy Klehm, Klehm's Song Sparrow Farm. According to Dr. Edward R. Hasselkus (Professor Emeritus of horticulture at the University of Wisconsin, Madison - Longenecker Gardens), "This cultivar has fine texture (small leaves, flowers, and fruits), and has a nice dense, slow-growing habit.” This cultivar is reported to have good quality foliage and uniform, compact habit. | 1931457 | Ames 33073 |
