Correlation analysis between groups of high-yielding and low-yielding cultivars for expression of the three genes, TaDr1, TaVrn1, and TaFT1 (right column), and between cultivars within each group (bottom row).

	High-yielding cultivars	Low-yielding cultivars	R2
TaDr1	2.17 ± 0.08	1.60 ± 0.15	0.081
TaVrn1	1.72 ± 0.10	1.06 ± 0.08	0.123
TaFT1	2.18 ± 0.10	1.55 ± 0.10	0.118
R2	0.897	0.957

Data represent the average of the relative expression units for four cultivars, with three biological replicates in each (n = 12) ± SE, extracted from Figure 4. The R² correlation coefficient was calculated using Tests of Between-Subjects.
