Linkage mapping and genetic analysis of Trypanosoma brucei
… T.b.brucei in many key phenotypes. The genetic linkage map was constructed from the analysis of 119 polymorphic microsatellite markers in a population of 38 F1 progeny, obtained from the genetic cross of a T.b.gambiense group 2 strain, STIB 386, with a T.b.brucei strain, STIB 247. Eleven major …

Genetic Characterization and Linkage Mapping of Barley Net Blotch Resistance Genes
… gene number and mode of inheritance, and conduct linkage mapping of novel genes for net blotch resistance. Results indicate that the highly resistant spring barley lines CIho 2291 and CIho 5098, and the winter barley cultivar Nomini each have single dominant genes for NTNB resistance. Resistance …

Linkage mapping in prairie cordgrass (Spartina pectinata Link) using genotyping-by-sequencing markers
… are currently hampered by the lack of a linkage map, the lack of a Chloridoid reference genome, and by lack of information on inheritance patterns (disomic versus polysomic). Genotyping-by-sequencing (GBS) was applied to a population of 85 progeny from a reciprocal cross of heterozygous …

Linkage mapping in tetraploid blackberry (Rubus spp.) using high-throughput genomic sequencing and restriction-site associated DNA sequencing (RAD-seq)
Genomic molecular marker research and linkage mapping in cultivated polyploid species of Rubus, in particular blackberry, has lagged behind diploid members of the genus due to the complex analyses required to deduce allele dosage among homologous and homeologous chromosomes. Traditional techniques …

Dissection of black rot resistance towards marker-assisted breeding in grapevine Pedigree reconstruction and phenotyping optimization coupled with high-density linkage mapping revealed a major QTL associated with bunch resistance.
… by three studies and the high-density link-age mapping allowed to reduce it from 2.4 to 0.7 Mb along the PN40024.v4 reference genome. The region resulted enriched in genes belonging to phloem dynamics and mitochondrial pro-ton transfer. The second QTL associated with bunch resistance was …

Genetic control of flowering time and biomass yield in sorghum
… exotic sorghum inbreds to perform association mapping for flowering time, biomass yield, and yield component traits. We also examined correlations between traits, correlations between inbred and hybrid performance, and the relationship between traits of interest and genetic diversity. …

Quantitative Trait Loci (Qtl) Analysis Of Sulfur Sensitivity In Vitis Aestivalis-Derived 'Norton'
… grape species and their commercial hybrids. A mapping population, consisting of 147 F1 genotypes, was created by crossing V. aestivalis-derived ‘Norton’ and V. vinifera ‘Cabernet Sauvignon’ to identify the genetic basis for sulfur sensitivity in North American wine grapes. Clonally propagated …

Linkage fine-mapping, GWAS and QTLs affecting morpho-agronomic traits of a common bean RIL population
… breeding is the DNA marker-assisted selection. Linkage mapping (LM) is the most common approach to detect molecular markers associated to quantitative trait loci (QTL). The abundance of molecular markers in the genome of the species made of association mapping (AM) a new methodology to QTLs …

Understanding C4 Photosynthesis Through Quantitative Genetics
… gynandra, this thesis aims to carry out linkage mapping and heritability estimates of C4 traits. Additionally, this thesis describes the generation of a Multi-Parental Advanced Generation Inter-Cross population and tools for high-throughput phenotyping of vein density, a trait integral to …

AFLP Marker Analysis Of Monoploid Potato
… phenotypes. Additionally, most major genetic mapping and QTL analyses in potato have utilized haploid germplasm to simplify linkage-mapping computations. The accuracy of genetic assumptions concerning the randomness and genetic purity of haploid genomes may directly affect the statistical …

Identification and Characterisation of the Barley Row-Type Gene <i>VRS3 </i>
… within the cereals. <br/>This study used genetic linkage mapping in segregating F2 populations to refine the genetic location of the row-type locus, <i>VRS3</i>, to 16 candidate genes on barley chromosome 1H. Sequencing candidate loci in 32 <i>vrs3</i> induced mutant alleles identified <i>VRS3</i> …

Development and Characterization of Microsatellite Markers for the Grain Amaranths (Amaranthus spp. L.)
… demonstrating the utility of these markers for linkage mapping of the amaranth genome. Phylogenetic analysis using the marker data showed A. hybridus accessions in two of the three major grain amaranth clades, suggesting the polyphyletic evolution of the three cultivated species from different …

Genomic and genetic resource for soybean disease resistance improvement
… (QTL) associated with seed number in a previous linkage mapping study, suggesting high efficacy of GWAS at identifying novel loci and confirming linkage mapping results. Marker-assisted selection and genomic selection (GS) were compared for prediction accuracy of SMV seed transmission rate. This …

Positional Cloning of Adiposity Genes in Ethnic Minorities of the Insulin Resistance Atherosclerosis Family Study
… during a time of transition from whole genome linkage mapping to genome-wide association study (GWAS) in human genetics, and this is reflected in its progression. Published results regarding the linkage-derived candidate gene Suppressor of Cytokine Signaling 3 (SOCS3), the GWAS-implicated …

Simultaneous Mapping and Pyramiding of Fusarium Head Blight Resistance Loci in Wheat Breeding Populations
<p>QTL linkage analysis for plants has relied on large single-cross mapping populations derived from phenotypically divergent parent lines. This approach creates a disjunction between QTL mapping and marker-assisted breeding efforts aimed at pyramiding QTL, since no direct bridge exists between the …
