General information


Phenotype ID: PETpet rm217P39
Name: Leaf obovoid
Species: Helianthus petiolaris subsp. petiolaris
Dataset: Helianthus petiolaris subsp. petiolaris. SNPs remapped to HA412-HOv2
Variation Type: continuous
Number of accessions: 161
Category: Leaf traits
Phenotype scoring: Obovoid is calculated from the maximum width (W), the height at which the maximum width occurs (y), the average width above that height (w1), and the average width below that height (w2), and a scaling function scale_ob
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. Calculated as: Obovoid = 1/2 * scale_ob(y) * (1 – w1/W + w2/W) If Obovoid > 0, subtract 0.4. Otherwise, Obovoid is 0
