Figure 6

Chromosomal positions and allelic effects of QTLs for the ratio of deep rooting (RDR) detected on chromosome 2 in the TaK-F2 population. (a) Peaks of the LOD curves indicate the putative positions of QTLs for RDR. Vertical lines in each linkage map indicate the genetic positions (cM) of DNA markers. Orange bar on the linkage map indicates 1.8-LOD support interval of RDR70, calculated by using the lodint function within the R/qtl software. DNA markers are shown under the linkage maps; the numbers in parentheses indicate their physical map positions (Mb) in the Nipponbare genome. The nearest DNA marker to the LOD peak of putative QTL for RDR70 (orange) is shown. (b) Frequency distribution of RDR70 in the TaK-F2 population showing three genotype classes of the DNA markers closest to the QTLs for RDR70. For each allele, an inverted triangle indicates the mean and a horizontal bar indicates SD. The same shading is used for triangles and corresponding bars. The means labeled with different letters differ significantly (P < 0.05, Tukey’s multiple comparison test).
