To provide a technique for determining the degree of quercetin content in individual onions.SOLUTION: The method for determining the degree of quercetin content in an onion seed plant comprises a step of determining at least one of a base itself (SNP) corresponding to any of the bases (a) to (d) below, or a continuous polynucleotide containing the base as a molecular marker for the quercetin content in onion seed plants: (a) the 41st base of a polynucleotide consisting of the base sequence shown in SEQ ID NO: 1; (b) the 55th base of the polynucleotide consisting of the base sequence shown in SEQ ID NO: 2; (c) the 106th base of the polynucleotide consisting of the base sequence shown in SEQ ID NO:3; and (d) the 73rd base of the polynucleotide consisting of the base sequence shown in SEQ ID NO: 4.SELECTED DRAWING: None 【課題】タマネギ個体におけるケルセチン含有量の程度を判定する技術を提供する。【解決手段】タマネギ種植物におけるケルセチン含有量の程度を判定する方法は、タマネギ種植物において、下記（ａ）～（ｄ）のいずれかの塩基に相当する塩基自体（ＳＮＰ）か、当該塩基を含む連続したポリヌクレオチド：（ａ）配列番号１に示す塩基配列からなるポリヌクレオチドの４１番目の塩基；（ｂ）配列番号２に示す塩基配列からなるポリヌクレオチドの５５番目の塩基；（ｃ）配列番号３に示す塩基配列からなるポリヌクレオチドの１０６番目の塩基；及び（ｄ）配列番号４に示す塩基配列からなるポリヌクレオチドの７３番目の塩基；の少なくとも１つを、タマネギ種植物におけるケルセチン含有量に関する分子マーカーとして判定する工程を含む。【選択図】なし
