Special Issue Information

Dear Colleagues,

Quantitative genetics has been used by plant breeders over the years to systematically select germplasm for crop improvement. This has been enhanced with the use of molecular markers, which enabled the identification of genes or quantitative trait loci (QTL), and consequently marker-assisted selection, for economically-important traits of interest. Advances in molecular marker and computer technologies have contributed to significant progress in the field of plant molecular quantitative genetics. The development of single-nucleotide polymorphism markers enables high-throughput genotyping at a lower cost. Modern computers can analyze large datasets, as well as conduct simulations, using complex statistical models. These recent developments are expected to improve efficiency in selecting the germplasm whose genotypic values best meet the breeder’s objectives.

The scope of this Special Issue covers different applications of molecular quantitative genetics in crop improvement, which includes, but is not limited to, QTL mapping, genome-wide association studies (GWAS), marker-assisted selection, and genomic selection. All types of articles, such as original research, opinions, and reviews, are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
A molecular marker is a valuable tool in genetic research. Insertions–deletions (InDels) are commonly used polymorphisms in gene mapping, analysing genetic diversity, marker-assisted breeding, and phylogenetics.

A molecular marker is a valuable tool in genetic research. Insertions–deletions (InDels) are commonly used polymorphisms in gene mapping, analysing genetic diversity, marker-assisted breeding, and phylogenetics. The 3000 Rice Genome Project, a re-sequencing project, discovered millions of genome-wide InDels. We found that the proportion of >50-bp long InDels (699,475) of the total (1,248,503) is 56.02%. The number of InDels on each chromosome was consistent with the corresponding chromosome length. The maximum InDels were on chromosome 1 (78,935), and the minimum InDels were on chromosome 9 (41,752), with an average density of 1.87 InDels/kb (range: 1.50–2.36 InDels/kb). Furthermore, 96 InDels of about 3.98 Mb/InDel were selected to detect the polymorphism. The results exhibited ideal performance in 2% agarose gel electrophoresis. Phylogenetic analysis exhibited that InDel markers had excellent polymorphisms between rice varieties of japonica and indica, and varieties could be classified based on the statistical results of their polymorphisms. The InDel markers could be applied to identify the recombinant inbred lines in a population. These results reveal that the high-density long InDel markers could help us examine the functional diversity, species variation, and map-based cloning. Full article
