In this study, the population panel consisted of 217 cultivars from differ- ent ecological regions (the Yellow River, the Yangtze River, the Northwestern inland region, the Northern China region, America and Australia) Phenotypic ana- lysis showed that the salt tolerance related traits in two. Recent years, association mapping as an important method for the identification of complex quantitative traits has been widely used in cotton for various traits including salt tolerance [35–40].

QTL mapping for soybean (Glycine max L.) leaf chlorophyll-content traits in a genotyped RIL population by using RADseq based high-density linkage map

tailieu.vn

The bin markers were corresponding to different chlorophyll-content traits QTLs in this study. In all, var- iations of the soybean leaf chlorophyll-content traits support the reported characteristics of quantitative traits [29–31].. This study aimed to explore QTLs for soybean leaf chlorophyll-content traits.. Some chlorophyll- content traits QTLs were identified by the bin markers that spanned relatively large genetic intervals (Additional file 1: Table S6).

Overlap between eQTL and QTL associated with production traits and fertility in dairy cattle

tailieu.vn

In the regions we detected, it was difficult to identify a se- quence variant that showed a strong association with both gene expression and quantitative traits, and per- mutation analysis showed that most, but not all, of the significant correlations between local GEBV and gene expression could be due to chance, generated by the high local LD.

Identification of selection signatures involved in performance traits in a paternal broiler line

tailieu.vn

Selection signatures in overlap with QTL in the TT line To identify selection signatures associated with quantitative traits, we investigated the overlap between the regions of cROH, F ST SNP and INDEL windows. About 72.8% of the 1941 cROH overlapped with QTL regions (n = 2617). There were also overlap of 60.1% of the 178 F ST SNP windows and 68.2% of the 154 F ST INDEL windows with QTL regions (n = 107 and 105, respectively)..

Genomic selection for non-key traits in radiata pine when the documented pedigree is corrected using DNA marker information

tailieu.vn

Conclusion: It was concluded that genomic selection with a pedigree corrected by SNP information was an efficient way of improving non-key traits in radiata pine breeding.. Genomic selection (GS) is an approach for improving quantitative traits in forest tree breeding populations that uses high density markers dispersed across the whole gen- ome [1–7]. There are two groups of individuals that are used in genomic selection:.

Genome-wide association studies of fertility and calving traits in Brown Swiss cattle using imputed whole-genome sequences

tailieu.vn

This gene may play a role in fertilization and therefore we propose the variant in the IGLL1 gene as a candidate variant for fertility traits in dairy cattle. There is additional evidence that the genomic re- gions of these QTL might affect quantitative traits in the Brown Swiss population because two complex copy number variant (CNV) regions have been found to be located at 72 – 73 Mb and 73 – 75 Mb [34] using the consensus map of CNV detected from PennCNV and SVS algorithms.

Evaluation of genetic diversity, agronomic traits, and anthracnose resistance in the NPGS Sudan Sorghum Core collection

tailieu.vn

Genomic characterization of the Sudan core collection could be used to study economically important traits and develop marker–trait association via GWAS. Deter- mination of the population structure is important for the identification of marker-trait association [46]. Popu- lation structure of the Sudan core set explained up to 25% of the observed phenotypic variation in quantitative traits including FL, PH, PL, and PD.

A time-dependent genome-wide SNP-SNP interaction analysis of chicken body weight

tailieu.vn

In the future, more research will be needed to better understand the genetic network of quantitative traits.. Our study demonstrated that the genetic interaction network of chicken body weight is time-dependent and the epistatic interaction effect is dynamic. To our knowledge, we are the first to describe and summarize the significant interaction effects that affect chicken body weight variation..

quantitative trait loci for economically important traits in Brown Swiss cattle. Across-cohort multi-trait meta-analyses of the results from the single-trait GWAS revealed 25 quantitative trait loci (QTL. Detected QTL explain between 2 and 10% of the variation in the estimated breeding values and thus may be considered as the most important QTL segregating in the Brown Swiss cattle breed.

DdRADseq-assisted construction of a highdensity SNP genetic map and QTL fine mapping for growth-related traits in the spotted scat (Scatophagus argus)

tailieu.vn

mapping for growth-related traits in the spotted scat (Scatophagus argus). As one of the most important economic traits, growth traits are controlled by multiple gene loci called quantitative trait loci (QTLs). A total of 6193 SNPs were grouped into 24 linkage groups (LGs), and the total length reached 2191.65 cM with an average marker interval of 0.35 cM. Based on the high-quality linkage map, a total of 44 QTLs associated with growth-related traits were identified on 11 LGs.
