*:非常に制限、**:制限、***:平均、****:大きい、*****:非常に大きい
[結果(ヘテロ接合体に関するQTL効果の評価以外を対象)]
−−:非常に乏しい、−:乏しい、=:並、+:適度、++:良好、+++:非常に良好

BCx:戻し交配のx周期後の戻し交配集団
RIL:組み換え近交系統
HIF:ヘテロ接合性近交母集団
DH:倍加半数体系統
SDR:第2分裂復元派生系統
倍加半数体およびSDR−0植物は、2つのホモ接合性(純性)キュウリ系統の間の交配から生じるF1から再生された。全ての個体DHおよびSDR−0植物は、AFLP手段によって、遺伝子表現型で分析された。
倍加半数体およびSDR−0植物の生成は、欧州特許0374755号に基づいて行われた。
DH−0およびSDR−0植物についてのAFLP分析は、ボス・ピー他(Vos P et al. (1995) Nucleic acids Research 23(21): 4407-4414)で説明されるように行われた。
データは、AFLPマーカーの相互優性評点が可能なQuantar・Pro(Keygene, Wageningen, The
Netherlands)で処理および分析された。
分離を見込める特性を以下に示す。
・頂部分割
・葉のサイズ
・成長速度
・ノードあたりの果実数
・ノード間長さ
・花のサイズ
・果実のサイズ
・果実の色
図10は、SDR−0およびDH−0植物についてのAFLP分析結果を示す。全ての個々の線は、各SDR−0植物の単一のDH−0植物を表している。全てのコラムは、連鎖群を表してる。DH系統とヘテロ接合性セグメント(薄灰色領域)を有する系統とを明確に区別して分類することができる。したがって、上記形質のSDR−1世代における分離は、ヘテロ接合性セグメントに関連している。
SDR−1世代における分離に関与する座の精細マッピングは、ペレマン・ジェイ他(Peleman J et al. (2005) Genetics 171: 1341-1352)に基づいて行われる。
