GenoTypeMapper: graphical genotyping on genetic and sequence-based maps

Abstract: Background The rising availability of assemblies of large genomes (e.g. bread and durum wheat, barley) and their annotations deliver the basis to graphically present genome organization of parents and progenies on a physical scale. Genetic maps are a very important tool for breeders but often represent distorted models of the actual chromosomes, e.g., in centromeric and telomeric regions. This biased picture might lead to imprecise assumptions and estimations about the size and complexity of ge… Show more

“…However, as mentioned in the results section, the drought stress effect in 2017 was mild but significant for most of the traits, except for CL, MSpTKW, and HI, and very clear for all traits in 2018 and 2019 (Figure 2, Supplementary Figure S4, Supplementary Table S5). In contrast to the previous studies by Peleg et al (2009) and Fatiukha et al (2020), no QTL for GY could be confirmed, but different segments of the introgressed wild emmer wheat region on chromosome 2B of NIL-U-2B-1 showed impacts on CL, CKN, and GY. The sub-NILs with the upper part of the emmer wheat QTL-interval had a shorter CL, more CKN, and a slightly higher GY, while sub-NILs with an introgression at the lower part of the QTL had longer stems, less CKN, and reduced GY (Figure 4; Table 4, Table 5).…”

“…Langdon) and wild emmer wheat (acc# G18-16) were phenotyped under contrasting water availabilities and used for QTL mapping ( Peleg et al, 2009 ; Fatiukha et al, 2021 ). Subsequently, the wild emmer QTL allele on chromosome 2BS conferring higher grain yield and harvest index (HI) was introgressed into the elite tetraploid durum wheat cultivar Uzan to develop the near-BC 3 F 3 isogenic line (NIL) NIL-U-2B-1 as previously described ( Merchuk-Ovnat et al, 2016 ; Deblieck et al, 2020 ). In this study, BC 3 F 3 NIL-U-2B-1 (pollinator) was crossed with Uzan ( Supplementary Figure S1 ) and BC 4 F 3 plants were screened with the respective flanking molecular markers to identify heterozygous recombinants.…”

“…The selection of flanking markers for the QTLs was based on a DArT map ( Peleg et al 2008 ; Merchuk-Ovnat et al, 2016a ). In 2020, another genetic map was created based on 15 K SNP array for the RIL 12 and NIL-B-7A-2 ( Deblieck et al, 2020 ; Fatiukha et al, 2021 ). Based on this new map, that included 4,015 SNPs, it was found that genetic material from Langdon is also present in the selected QTL region.…”
