Open AccessConstruction of a high-density linkage map and graphical representation of the arrangement of transcriptome-based unigene markers on the chromosomes of onion, Allium cepa L.
Genomic information for Allium cepa L. is limited as it is heterozygous and its genome is very large. To elucidate potential SNP markers obtained by NGS, we used a complete set of A. fistulosum L.-A. cepa monosom...

QTL analysis for pseudostem pungency in bunching onion (Allium fistulosum)
Low pungency is one of the most important agronomic traits in bunching onion (Allium fistulosum L.). Although the degree of pungency can be evaluated indirectly using a colorimetric test for pyruvic acid, DNA mar...

Direct determination of the chromosomal location of bunching onion and bulb onion markers using bunching onion–shallot monosomic additions and allotriploid-bunching onion single alien deletions
To determine the chromosomal location of bunching onion (Allium fistulosum L.) simple sequence repeats (SSRs) and bulb onion (A. cepa L.) expressed sequence tags (ESTs), we used a complete set of bunching onion–s...
