Geographic location of data collection: University of Minnesota Horticultural Research Center (previously Fruit Breeding Farm) at 44.867793 N,-93.635015 W 5. Information about funding sources that supported the collection of the data: Mainly Minnesota Agricultural Experiment Station and Department of Horticultural Science (older names were Department of Horticultural Science and Landscape Architecture and Department of Horticulture). -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

File List A. Filename: Dwarf apple dead 978-1631.pdf Description: Phenotype records for apple varieties and selections (978-1631) grown on dwarf rootstocks, some with interstems that died or were culled. Observations started in 1950 and continued until 1970. First selections entry is #978 on #1561. Last entry is #32. Several named cultivars are also included. B. Filename: Dwarf apple dead L-Z.pdf Description: Phenotype records for apple varieties and selections that died or were culled as grown on dwarf rootstocks, some with interstems. Observations started in 1950 and continued until 2018. First entry is #1563. Last is Yellow Transparent. 2. Relationship between files: Files refer to different time periods, and different selections, as noted above. However, they are all part of the same collection. -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Trees of various scion cultivars or University of Minnesota numbered breeding selections grafted on various dwarfing or hardy rootstocks were planted in Blocks 11 and 20 at the HRC in the 1950s. Notes were taken annually on cropping and other traits. The records in this collection are mainly for trees observed through 1965. 2. People involved with data collection: As stated above, since the data was collected over large periods of time, it is unclear who authored each page/dataset.
