The correlation of the GD assessed by SSR and SNP markers was significantly positive (0.264 ≤ r ≤ 0.375, P <. Furthermore, 1128 F 1 hybrids clustered into five groups based on GD assessed through SNP markers and named as group I, II, III, IV and V, having and 280 F 1 , re- spectively (Fig. Table 1 Summary of genetic distance estimated between parents using both SSR and SNP markers.

Nonetheless, DNA sequencing is more costly than the use of array-based SNP markers, al- though extensive validation of the SNP markers is needed before they can be used for genetic diversity studies.. This is a reflection of the higher numbers of SNPs detected by genome resequencing methods..

A total of 24 SNP markers located in the confidence inter- vals of body weight QTLs were selected and utilized to identify candidate growth-related genes. 1 Illustration of the high-density SNP consensus linkage map of S.argus. These candidate genes are worthy of further studies to reveal their exact roles in genetic control of growth traits in the future..

InDel markers combine the characteristics of both SSR and SNP markers, in particu- lar integrating advantages of abundance and simplicity.. Full list of author information is available at the end of the article. Thus, InDel markers are a valuable complement for both SSR and SNP markers in genetic studies [9, 10]. The de- velopment of InDel markers is becoming readily access- ible because of the rapid development of next- generation sequencing (NGS).

SNPs are the most abundant genetic variations in most plant species, and the exploitation of SNP markers in single-copy regions is considerably easier than use of the other DNA markers [14–16]. InDel markers have prac- tical value for those laboratories with limited resources, which also showed reliable transferability between dis- tinct populations . Several stud- ies have also reported the development and application of SNP/InDel markers in tea plant genetic studies.

Following the filtering of the SNP markers and of the silicoDArT markers were retained.. The highest quality markers mapped at a single position, with a score of 100, constituted 25.7 and 38.8% of the SNP and silico- DArT markers, respectively (Table S3).. The heterozygosity of the SNP markers did not exceed 0.75, with 10,310 markers exhibiting a heterozygosity of less than 0.1 (Fig. Additional analyses were performed to clarify the in- creased heterozygosity of the markers in subgenome D..

This PIC value was reported as a good indicator of informative markers which could be used in study- ing the genetic diversity in the different organisms [34]. Based on the PIC values in our tested popula- tion and the good distribution of the studied SNP markers, we can conclude that these markers ex- plained the genetic diversity in spring wheat and could be used in other genetic studies such as genome-wide association study to identify alleles con- trolling target traits..

Concerning predictive markers for qTA5a, each of the two SNP markers can distinguish the Q and q alleles (ss_544428 at 557,504 bp and ss_544495 at (610,569 bp) (Table 3, Additional file 1: Table S6). For qTA5b’s, QTL genotypes could be predicted by various pairs of SNP markers that include ss_600509 combined with one of the six markers ss_600072, ss_. The identity of the SNP markers and their physical and genetic location are given in Additional file 1: Table S6 (Continued).

The DArT markers were scored as binary data (0/1) indicating the presence or ab- sence of a marker in each accession, and the SNP markers were scored as 0/1/2 indicating the presence of the reference allele in homozygosity, the alternative al- lele in homozygosity or a heterozygous genotype, re- spectively. To locate the markers in the.

To avoid the presence of paralogous sequences, several filters can be applied, such as a check on the read depth at the SNP site and/or a kmer analysis of the probes of selected candidate SNP markers. For example, it is possible to align the entire probe (or multiple subsequences of the probe i.e., kmers) against the reference genome and make sure that these sequences do not appear multiple times across the gen- ome.
