Figure 3.

Heatmap showing DBR Range values for 35 wheat genotypes over days after sowing from 104 to 147, with genotypes grouped by drought response categorized as high, moderate, or low. Color transitions from green to red indicate a decrease in DBR values over time and correspond with the drought response classifications.

Heat map of the digital biovolume ratio (DBR) for 35 durum wheat genotypes at six different time points. The DB was acquired in the high-throughput phenotyping platform from 104 days after sowing (DAS) when the drought stress was imposed, until 139 DAS. For each genotype, the corresponding classification of low, moderate, and high drought resilience is reported.
