From: Image analysis for the automatic phenotyping of Orobanche cumana tubercles on sunflower roots
Various susceptibility/resistance phenotypes observed at the tubercle stage using RhizOSun. Phenotyping using RhizOSun: images of 3-week-old inoculated roots (left side, a-c-e) and identified particles using automatic image analysis (right side b-d-f). a-b Susceptible sunflower genotype MSL2 inoculated with the O. cumana race Bourret. c-d Tolerant sunflower genotype MSL2 inoculated with race KZP: low number of tubercles and development of necrotic tubercles. Necrotic tubercles (arrowheads) were not counted automatically, as shown in d, due to their brown color. e–f Resistant sunflower genotype BR3 inoculated with the race Bourret (no tubercles).
