Comparison of two linkage groups of the developed map with the tetraploid reference map (Varshney et al. ). LG1 and LG 8 of TAG 24 × GPBD 4 aligned through common markers with LG_AhIX and LG_AhIII of TAG 24 × ICGV86031, respectively. These common markers in both linkage maps are in the same order

Comparative mapping of IPAHM 103, diagnostic marker for rust QTL (QTL_rust01) and other linked markers between TAG 24 × GPBD 4 and TG 26 × GPBD 4 mapping populations. Three markers namely IPAHM 103, pPGSseq19D6 and IPAHM 272 show collinearity between two maps. Furthermore, three additional markers, namely PM36, TC1D12 and TC9B8 have been integrated in the QTL (QTL_rust01) region in TG 26 × GPBD 4 mapping population

A snapshot showing the occurrence of a major QTL (QTL_rust01) on LG 6 for rust based on phenotyping data obtained for different stages of infection under five environments. Different environments and stages of phenotyping in the figure have been abbreviated as follows. Environments: ER-I Rainy 2004, ER-II Rainy 2005, ER-III Post-rainy 2007, ER-IV Rainy 2007, ER-V Rainy 2008. Stages: LR-I phenotype scored at 70 days after sowing (DAS), LR-II phenotype scored at 80 DAS, LR-III phenotype scored at 90 DAS, LR-IV phenotype scored at 105 DAS, LR-V phenotype scored at 113 DAS, LR-VI phenotype scored at 120 DAS, IP incubation period, LP latent period, IT infection type. X-axis shows the linkage group 6 (LG 6) with relative position of different markers and Y-axis shows the LOD value for which QTL for rust has been detected for the above-mentioned environment/stage

Genetic linkage map based on TAG 24 × GPBD 4 population showing QTL positions for LLS and rust. Seven linkage groups each have been shown in a (LG 1–LG 7) and b (LG 8–LG 14). Asterisk represents the markers showing segregation distortion. Distorted markers are indicated with suffix “a” indicating markers from tetraploid reference map (Varshney et al. ). Numbers on the left of each linkage group are Kosambi map distances. On the right hand side of the linkage groups, QTLs for LLS and rust, as mentioned in Tables , and , have been shown using the following boxes: Open rectangle indicates QTL for LLS; rectangle with diagonal lines indicates QTL across the environment for LLS; closed rectangle indicates QTL for rust
