A Deep Learning-Based Phenotypic Analysis of Rice Root Distribution from Field Images

Figure 1

Overview of root distribution parameter estimation. (a) Rice plants were cultivated in the field; the ditch was created with a backhoe, and the trench profile image was acquired. (b) Upper right: in 2018, 30 trench profile images were manually annotated and used for model construction. Two root distribution parameters were defined, and the trained model was validated. (b) Lower right: in 2019, 204 trench profile images were used to assess the phenotypic diversity of root distribution among worldwide rice accessions.
