TABLE 4.

Evaluation of agronomic traits of two pBDL23-transformed marker-free rice lines.

	Spike number	Flag leaf length (cm)	Plant height (cm)	Spike length (cm)	Heading date (day)
14YD270-1(Ds+)	11 ± 5	29.50 ± 4.57	72.71 ± 7.96	15.89 ± 1.99	147.75
14YD270-1(Ds−)	12 ± 4	29.21 ± 3.87	72.37 ± 6.73	15.63 ± 1.69	147.75
t-test	−0.242	0.167	0.116	0.348	ND
P-value	0.81	0.87	0.91	0.73	ND
14YD273-2(Ds+)	13 ± 4	21.97 ± 2.14	59.76 ± 4.70	14.32 ± 1.01	147.25
14YD273-2(Ds−)	13 ± 3	23.08 ± 2.09	62.08 ± 3.72	14.88 ± 1.65	148.25
t-test	0.523E-01	−1.22	−1.26	−0.982	ND
P-value	0.96	0.24	0.22	0.34	ND

For t-tests, Ds-negative (Ds−) plants in the marker-free transgenic lines were used as control in comparison with the Ds-positive (Ds+) plants. ND, not determined.
