description: This file contains the raw phenotypic data, with one value per individual tree and per year, for phenology, productivity, fruit size, outer fruit, inner fruit, and vigor traits evaluated in the apple REFPOP over up to three seasons. It contains the following columns: - Year: year of evaluation – Country: location of evaluation, labeled as BEL (Belgium), CHE (Switzerland), ESP (Spain), FRA (France), ITA (Italy) and POL (Poland) – Row: row within the orchard where the tree was located – Position: position of the tree within the row – Genotype: genotype identifier – Management: management applied to the tree (M1: integrated pest management, M2: possibility of alternative management, these data are not made available yet) – Harvest_date: harvest date, in days from January 1st – Flowering_begin: date when the first 10% of flowers opened, in days from January 1st – Flowering_full: date when at least 50% of flowers were open, in days from January 1st – Flowering_end: date when all flower petals fell off, in days from January 1st – Flowering_intensity: percentage of existing flowers from the maximum possible number of flowers – Fruit_weight: weight of the full set of produced fruits, in kilograms – Fruit_number: all produced fruits counted on harvest date – Fruit_weight_single: average weight of a single fruit, in grams, obtained by dividing the weight of all fruits by the number of fruits – Color_ground: ground color visually scored using a scale from zero to two (0 = green, 1 = green-yellow/yellow-green, 2 = yellow), estimated for a fruit batch* – Color_over: percentage of red fruit skin visually scored using a scale from zero to five (0 = 0%, 1 = 1-20%, 2 = 21-40%, 3 = 41-60%, 4 = 61-80%, 5 = 81-100%), estimated for a fruit batch* – BitterPit_freq: percentage of apples showing symptoms of bitter pit, estimated for a fruit batch* – BitterPit_grade: intensity of bitter pit symptoms, visually scored using a scale from zero to two (0 = no symptoms, 1 = medium symptoms, 2 = very high symptoms), estimated for a fruit batch* – Russet_cover: percentage of the fruit surface covered by russet visually scored using a scale from zero to five (0 = 0%, 1 = 1-20%, 2 = 21-40%, 3 = 41-60%, 4 = 61-80%, 5 = 81-100%), estimated for a fruit batch* – Russet_freq_all: percentage of apples showing russet, estimated for a fruit batch* – Russet_freq_stalk: percentage of apples showing russet in the stalk basin, estimated for a fruit batch* – Russet_freq_cheek: percentage of apples showing russet on the cheek, estimated for a fruit batch* – Russet_freq_eye: percentage of apples showing russet in the eye basin, estimated for a fruit batch* – Acidity: titratable acidity, measured in grams of titratable acid per liter of solution, using the juice samples of ten fruits analyzed with an automated instrument Pimprenelle – Sugar: soluble solids content measured as a refraction index in degrees Brix with an automated instrument Pimprenelle, mean value over ten fruits analyzed separately – Firmness: fruit firmness measured using a penetrometer on an automated instrument Pimprenelle in g/cm², mean value over ten fruits analyzed separately – Water_core_freq: percentage of apples showing symptoms of water core, estimated for a sample of ten fruits – Water_core_grade: intensity of water core symptoms, visually assessed on a scale from zero to six, estimated for a sample of ten fruits – Trunk_diameter: trunk diameter at 20 cm above the grafting point, measured in mm before the onset of flowering using a digital caliper or estimated from trunk circumference (ITA) – Trunk_increment: difference in mm in trunk diameter between the current and previous year; *a fruit batch consisted of 20 fruits selected randomly or all produced fruits for trees bearing at least five and up to 20 fruits.
