Erratum to: Identification and mapping in spring wheat of genetic factors controlling stem rust resistance and the study of their epistatic interactions across multiple environments

Erratum to: Theor Appl Genet (2013) 126:1951–1964 DOI 10.1007/s00122-013-2109-6

In the original article, chromosome 6B was erroneously listed as 5A. This led to the propagation of the error from Figure 4 to Table 1 and four locations within the text. The overall scope of research and interpretation are not impacted by the error.

Revision #1 in Abstract (page no. 1951)

Incorrect: Carberry contributed resistance QTL on 4B and 5A.

Corrected to: Carberry contributed resistance QTL on 4B and 6B.

Revision #2 in Results (page no. 1955)

Incorrect: Those QTL that appeared only for traits measured in Canada were QSr.spa-3B.1, QSr.spa-5A, QSr.spa-5B.1 and QPbc.spa-6A and those QTL that appeared for traits measured in Kenya and Canada were QPbc.spa-3B.1, QSr.spa-4B.1 and QSr.spa-6D.

Corrected to: Those QTL that appeared only for traits measured in Canada were QSr.spa-3B.1, QSr.spa-6B, QSr.spa-5B.1 and QPbc.spa-6A and those QTL that appeared for traits measured in Kenya and Canada were QPbc.spa-3B.1, QSr.spa-4B.1 and QSr.spa-6D.

Revision #3 in Results (page no. 1957)

Incorrect: AC Cadillac contributed resistance at the QSr.spa-2B.1, QSr.spa-3B.1, QSr.spa-5B.1, QSr.spa-6D, QSr.spa-7B and QSr.spa-7D loci while Carberry contributed resistance at the QSr.spa-4B.1 and QSr.spa-5A (Table 1).

Corrected to: AC Cadillac contributed resistance at the QSr.spa-2B.1, QSr.spa-3B.1, QSr.spa-5B.1, QSr.spa-6D, QSr.spa-7B and QSr.spa-7D loci while Carberry contributed resistance at the QSr.spa-4B.1 and QSr.spa-6B (Table 1).

^aMarker interval described by the markers which immediately flank the peak QTL response, or in the case of a single marker, the marker which is at the peak QTL response

^bThe threshold to declare LOD scores significant ranged from 2.9 to 3.0. All LOD scores reported are significant

^cA positive additive effect indicates Carberry contributed to stem rust resistance and a negative additive effect indicates AC Cadillac contributed to stem rust resistance

^dPV is the proportion of the phenotypic variance explained by the QTL

Revision #4 in Discussion (page no. 1962)

Incorrect: We detected a number of less impressive main effect QTL, such as QSr.spa-5A on chromosome 5A which appeared only in the Canadian environment suggesting the gene is only effective to North American races. Njau et al. (2012) recently reported a QTL on chromosome 5A, but due to differences in markers between linkage maps it is difficult to ascertain whether their marker is the same as QSr.spa-5A.

Corrected to: We detected a number of less impressive main effect QTL, such as QSr.spa-6B on chromosome 6B which appeared only in the Canadian environment suggesting the gene is only effective to North American races.

Revision # 5 in Figure 4 caption (page no. 1959)

Incorrect title: Fig. 4 Stem rust resistance QTL identified on chromosome 2B, 3B, 4B, 5, 5B, 6, 7B and 7D and pseudo-black chaff (PBC) QTL identified on chromosome 2B, 3B and 6A, using DArT and SSR markers in a doubled haploid population derived from Carberry/AC Cadillac. Disease reactions for stem rust severity, infection response and PBC were assessed near Njoro, Kenya (2009, 2010 and 2011) and near Swift Current, Canada (2011 and 2012), and seedling stem rust infection type was assessed in Morden, Canada (2009 and 2012). Location of a QTL involved in epistasis is depicted with the symbol asterisk
