Chromosomal positions and allelic effects of QTLs for the ratio of deep rooting (RDR) detected on chromosomes 2, 4, and 6 in the YuK-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. Red and orange bars on the linkage maps indicate 1.8-LOD support intervals of RDR50 and RDR70, respectively, 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 markers to the LOD peaks of putative QTLs for RDR50 (red) and RDR70 (orange) are shown. (b) Frequency distributions of RDR50 and RDR70 in the YuK-F2 population showing three genotype classes of the DNA markers closest to the QTLs for RDR50 and RDR70, respectively. 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).
