From: RGB image-based method for phenotyping rust disease progress in pea leaves using R
Pea rust evolution assessed with the RGB-based method. (A) The images show the evolution of rust pustule development at three different days after inoculation (8 dai, 10 dai, and 12 dai) on a representative leaflet of three differential genotypes (GEN62, GEN56, and GEN261) covering the wide range of susceptibility detected in the collection. White spots on the images indicate rust pustules detected by the image-based analysis methods. (B) Line plots showing the progression of disease severity (DS), pustule size (PS) and infection frequency (IF) over time estimated from these genotypes with the RGB-based method
