Relative expression of the hth gene as determined by quantitative RT-PCR

Apple line	Relative hth expression	Significant difference (P = 0.05)
G-Co (hth−)	0.0000
E-Co (hth−)	0.0000
G-GMCo (hth−)	0.0000
G-56	0.5867	a
G-15	0.6000	a
E-06	0.8467	ab
G-68	1.0033	b

The values represent the mean relative expression of three individual trees sampled per line (for line G-56 six individuals were measured). Different letters in the last column point at significant differences between the lines at the P = 0.05 level (SD = 0.18)
