Abstract

Onions (Allium cepa L.) contain quercetin glycosides.
Quercetin in onions is in high demand in the market as a functional ingredient.
However, it takes long time to breed a cultivar with high quercetin glycoside content as it varies depending both on genetic and environmental conditions, and how these factors change it.
To develop a DNA selection marker for quercetin glycoside content in onions, we analyzed segregating F₂ populations derived from crosses of cultivars with different quercetin content.
In 2019, F₂ populations (n=204) were grown in the field.
DNA and bulb weight were obtained from each F₂ plant, and genotyping data were obtained using an amplicon sequence with 129 SNP markers.
The linkage map consisted of 11 linkage groups, 817.6 cM in total.
The quercetin glycoside content in each F₂ onion bulb was analyzed by HPLC. Four QTLs located on chromosomes 1, 5, 6 and 7 were detected.
Two QTLs located on chromosomes 5 and 6 were found to regulate quercetin glycoside content per unit dry matter weight, whereas the others were more influenced by onion bulb weight rather than by quercetin glycoside content.
In 2020, F₂ individuals (n=169) from the same population were grown in the field and the quercetin glycoside content of the bulbs was evaluated.
By comparing quercetin glycoside content and genotypes of the neighboring QTL markers, one QTL was found to be located on chromosome 6 was significant for the quercetin glycoside content.
This QTL is novel on chromosome 6 and can be selected for quercetin content in onions.
We also validated F₃ families whose genotype was heterozygote in F₂ matched the quercetin glycoside content and the marker genotypes.
Therefore, this QTL marker is useful for efficient breeding to improve the quercetin glycoside content in onion.
