This Article contains errors in Table 1. In the HTML and PDF versions of this Article, the denotation of the genes used in F3-F6 generations, and F7 and subsequent stable generations is incorrect.

Table 1

Names and their primer sequences of markers used in the marker assisted selection of Zhengmai 7698. *: genes used in F3-F6 generations; **: genes used in F7 and subsequent stable generations; √: the existence of that gene. The primers of markers Pm2, Pm4b and Pm8 were presented, respectively, in Mohler et al. Theor Appl Genet 93: 1078–1082 (1996), Ma et al. Theor Appl Genet 109: 140–145 (2004) and Wang et al.

Additionally, the legend of Table 1 is incorrect:

“Table 1. Names and their primer sequences of markers used in the marker assisted selection of Zhengmai 7698 (the label √ means the existence of that gene).”

should read:

“Table 1. Names and their primer sequences of markers used in the marker assisted selection of Zhengmai 7698. *: genes used in F3-F6 generations; **: genes used in F7 and subsequent stable generations; √: the existence of that gene. The primers of markers Pm2, Pm4b and Pm8 were presented, respectively, in Mohler et al. Theor Appl Genet 93: 1078–1082 (1996), Ma et al. Theor Appl Genet 109: 140–145 (2004) and Wang et al. Acta Genetica Sinica 28(7), 640–646 (2001).”

The correct Table 1 and its accompanying legend appears below.

This Article contains errors in the Results section under subheading ‘Molecular markers for Zhengmei 7698’.

“In the F3–F6 generations of the selection processes, seven superior genetic markers in the parents were used (genes underlined by straight line in Table 1) to monitor the progress of gene pyramiding in hybrid offspring (e.g., single plant and line), and in the F7 and subsequent stable generations, and 19 newly developed genetic markers were progressively added (genes underlined by wavy line in Table 1).”

should read:

“In the F3–F6 generations of the selection processes, seven superior genetic markers in the parents were used (genes denoted with an * in Table 1) to monitor the progress of gene pyramiding in hybrid offspring (e.g., single plant and line), and in the F7 and subsequent stable generations, and 19 newly developed genetic markers were progressively added (genes denoted with an ** in Table 1).”

Furthermore, this Article contains errors in the Reference list. References 15, 18, 22 and 23 are incorrectly given as follows:
