Links to publications that cite or use the data: Many publications by researchers at the Horticultural Research Center have utilized the fruit breeding data. --------------------- DATA & FILE OVERVIEW --------------------- 1. File List A. Filename: Apple dead AE numbers.pdf Description: Phenotype records for apple seedlings that were culled. First entry is AE4913. Last is AE5024. Range from AE4913 to AE4931; AE501 to AE5024. -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: A record was produced for each seedling tree from crosses made in 1949 (AE49xx) and 1950 (AE50xx) as indicated by row and tree numbers for phenotype and performance in the orchard. The trees were planted in the HRC Block 74 orchard in 1955 at 5 ft spacing in the row and 15 feet between rows The records in this collection are for seedlings that were observed from 1955 through 1970. 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.
