Data were largely collected in line with the published ECPGR Characterization and Evaluation Descriptors for Pear Genetic Resources with additional locally agreed descriptors. The dataset contains scores across 24 traits from 573 accessions. Cite as: Ordidge, Matthew; Hale, Penny (2025) Characterization and Evaluation data from the National Fruit Collection 2025_Pear.

CONTENTS ------------ File listing NFC_C_E_data_Pear_21_08_25.csv Data are presented in the form of a .csv file and represent characterization and evaluation descriptor scores for accessions in the National Fruit Collection (past and present). Columns 1-7 contain Accession names, Accession numbers, Row, Tree and Collection location data as well as notes on whether accessions are current and/or whether data are available in the EURISCO database. Columns 8-10 and 48, 51 and 54 contain details on the dates of sample harvest, recording and details of the recorder in relation to the scores in subsequent columns. Descriptors are generally presented in both written descriptive and numerical rated format. 5. METHODS ----------- Data were generally scored following protocols published by ECPGR (https://www.ecpgr.org/resources/ecpgr-publications/publication/ecpgr-characterization-and-evaluation-descriptors-for-pear-genetic-resources-2022 accessed 21/08/25). Additional 'local' descriptors were added to categorise 'Fruit shape' and calculate 'Mean fruit weight' (based on an average of ten fruit). 'Curvature of stalk' was scored in line with UPOV 2003 descriptor 52 (https://www.upov.int/edocs/tgdocs/en/tg015.pdf). Data were collected over a period of time (approx 2006-2024) with sampling as indicated in the file. The location of the collection is 51.29979, 0.87834. Where the scorer's judgement was that more than one category was represented, data have been standardised to the main or median state. Data collectors (P.Hale, A. Lean) are detailed in the file, data have been collated by M Ordidge (as above).
