Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this study, we developed single nucleotide polymorphism (SNP) markers to identify cultivars of the polyploid Rosa hybrida using genotyping-by-sequencing (GBS). Sequences obtained from GBS libraries of the genomes of 79 rose cultivars were aligned to contigs created by de novo assembly, and these contigs ranged from 200 to 2,591 bp, with an average of 305 bp per contig. We selected 1,778 SNPs from 13,488 putative SNPs. SNP markers that were present in more than 70% of the 79 cultivars were selected and evaluated, both on the basis of polymorphism information content values and level of heterozygosity, and 20 SNP markers were ultimately selected for high- throughput analysis. From these 20 SNP markers, 4 were successfully converted to markers for DNA chip assays. High resolution melting analysis was carried out to further distinguish rose genotypes. Using a set of seven SNP markers, we identified 70.9% of the 79 rose cultivars, and 87.5% of the 16 new cultivars developed in Goyang City. This paper is the first to report the development of a SNP marker set to identify Rosa hybrida cultivars by GBS.
