市販のステビア植物体を、RebD又はRebMの含量に着目して3世代にわたり選別交配を行い、高RebD含有集団A及び高RebM含有集団Bを得た。さらに集団A及びBを交配し、分離集団Cを得た。
集団Cの成長した各個体より適量の新鮮葉をサンプリングし、LC-MS/MS(島津LCMS8050)にてステビオール配糖体の濃度を定量した。具体的には、0.25gの新鮮葉をフリーズドライにより乾燥し、破砕乾物0.05gを100倍量(5mL)の純水中に投入した。超音波処理20分にて抽出し、遠心・濾過した後、32%アセトニトリルで60倍希釈したものをサンプル液とした。このサンプル液1mLをLCMS8050のMRMモードにてLC-MS/MS分析を行い、RebA、RebB、RebC、RebD、RebE、RebF、RebG、RebM、RebN及びステビオシドの濃度を定量した。さらに、集団Cの一部の個体の新鮮葉からゲノムDNAを抽出し、シーケンサー(HiSeq 2500、Illumina)により遺伝子解析を行った。結果を表2~3に示す。表中、ステビオール配糖体の数値は、乾燥葉における重量%を示し、遺伝的特徴は、「+」が陽性、「-」が陰性を示す。又、「STV」はステビオシド、「TSG」は総ステビオール配糖体をそれぞれ示す。なお、TSGの数値は測定した全てのステビオール配糖体(すなわち、RebA、RebB、RebC、RebD、RebE、RebF、RebG、RebM、RebN及びステビオシド)の合計値である。
次に、測定した各ステビオール配糖体の含量と本発明の遺伝的特徴との関連性について検討した。具体的には、集団C~Eを合わせた集団において、本発明の遺伝的特徴を有する個体群とそれ以外の個体群とで、各ステビオール配糖体の含量について統計学的な有意差があるかをウェルチのt検定で評価した。結果を表8に示す。表中、例えば「遺伝的特徴1」の結果は、遺伝的特徴(1)を有する個体群とそれ以外の個体群(すなわち、遺伝的特徴(1)を有する個体以外の個体群)における各ステビオール配糖体の含量を分析した結果であり、「遺伝的特徴1+2」の結果は、遺伝的特徴(1)と(2)を両方有する個体群とそれ以外の個体群(すなわち、遺伝的特徴(1)と(2)を両方有する個体以外の個体群)における各ステビオール配糖体の含量を分析した結果であり、「遺伝的特徴1/2/3」の結果は、遺伝的特徴(1)、(2)及び(3)の少なくとも1つを有する個体群とそれ以外の個体群(すなわち、遺伝的特徴(1)、(2)及び(3)のいずれも有しない個体群)における各ステビオール配糖体の含量を分析した結果である。又、「+」はP<0.05、「++」はP<0.01で遺伝的特徴を有する個体群の方が、それ以外の個体の個体群より含量が多いこと、「-」はP<0.05、「--」はP<0.01で遺伝的特徴を有する個体群の方が、それ以外の個体の個体群より含量が少ないこと、「±」は、両個体群の含量が有意水準0.05で有意差が認められなかったことをそれぞれ示す。
