Table 5: Correlations between flower volume after 7 days of treatments (VolF_DAT7) and phenomic and agronomic traits across 12 Brassica genotypes under nonstress (control), drought, heat and combined heat, and drought stress conditions. Traits without significant correlations (p ≥ 0.05) are not shown.

Phenomic traits are indicated as in Table 3. The three agronomic traits are seed yield per plant (SY), 100-seed weight (SW), and fresh weight of above-ground plant at DAT7 (FW). Correlation (r) significance values are shown as p <0.05 ( ) and <0.01 ( ).
