However, only QTL6.1 actually resided within the confidence interval of QTLGLSchr6 identified in the DH mapping population, suggesting that both QTL6.1 and QTLGLSchr6 represent the same GLS resistance locus.
While TrPPD was the only candidate gene to be mapped in both homoeologues, many of the other genes exhibited additional amplicons that were not informative in the mapping population suggesting they may have loci elsewhere in the genome, including other homoeologues and paralogues.
The frequencies of unique Solexa paired-end sequences in the tagged SRAP PCR products showed continuous variations among the individual RI lines of the mapping population, suggesting that two alleles of these polymorphic loci that corresponded to these unique Solexa paired-end sequences were amplified differentially in SRAP PCR.
Few meta-QTL specificities were observed among mapping populations, suggesting that sources of resistance are not independent.
Of particular interest for map merging is the fact that 123 SSRs (87 GSSRs and 36 BSSRs) were polymorphic in two or more mapping populations, suggesting that these common markers may serve as anchoring points across maps.
The present work identified 123 SSRs (87 GSSRs and 36 BSSRs) that were polymorphic in two or more mapping populations, suggesting that these common markers may serve as anchoring points for merging carrot maps.
The observation that I. fulva alleles are overrepresented in both mapping populations suggests that I. fulva alleles are favored to introgress into I. brevicaulis genetic backgrounds, while I. brevicaulis alleles would tend to be prevented from introgressing into I. fulva.
hirsutum), 689 (52.3%) of the verified SNPs were also found to be polymorphic between two standard varieties (TM-1: G. hirsutum; 3−79: G. barbadense) commonly used in cotton genetics and generation of a number of mapping populations, suggesting that our SNPs should be useful more broadly in both cotton genetics and breeding.
The validation of these TF gene-derived SSR markers at SW-influencing QTL region in two of our independent studies using two different intra-specific (ICCX-810800 × ICC 20268) and inter-specific (ICC 4958 × ICC 17160) mapping populations suggests the robustness and significance of identified TF genes underlying QTLs for controlling seed weight in chickpea.
Initial observations (Hall et al. 2010) suggested an area of suppressed recombination in a recombinant inbred line mapping population made from an inland × coastal cross.
