General information

Phenotype ID: PETfal rm216P36
Name: Leaf ellipsoid
Species: Helianthus petiolaris subsp. fallax
Dataset: Helianthus petiolaris subsp. fallax. SNPs remapped to HA412-HOv2
Variation Type: continuous
Number of accessions: 203
Category: Leaf traits
Phenotype scoring: The ratio of the error resulting from a best-fit ellipse to the area of the leaf. Error is the average magnitude of residuals (Res) along the leaf’s perimeter, divided by the length of the major (longer) axis of the ellipse. Smaller values indicate that t
Source: None
Description: The youngest, fully developed leaf from the primary stem was collected at anthesis and scanned on a flatbed scanner, at a resolution of 300 dpi. A size and colour standard was included in each picture. For morphometric measurements, colours were inverted in Adobe Photoshop to increase contrast. Images were analyzed using Tomato Analyzer (Rodrigues. et al. 2010); leaf boundaries were manually adjusted when necessary.
