General information


Phenotype ID: PETfal rm216P37
Name: Leaf circular
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 circle to the area of the leaf. Error is the average magnitude of residuals (Res) along the leaf’s perimeter, divided by the radius of the circle. Smaller values indicate that the leaf is more circular
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.
