Phenotypic data with emphasis on fire blight observed in early 1960s. Species included: apple/Malus -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Files contain both narrative descriptions and relative numerical performance ratings, often over several years, on morphological and horticultural traits of trees and fruits for apple or cherry selections. Several files emphasize relative ratings of susceptibility of apples to fire blight as observed during a natural epidemic period in the orchards in the 1960s. 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.
