The present invention relates to a method for breeding a novel plant variety of high fertility xBrassicoraphanus with stabilized seed productivity, and discloses a method for breeding a novel plant variety of xBrassicoraphanus, which involves performing a mutagen treatment on xBrassicoraphanus seeds by treating the xBrassicoraphanus seeds with 0.01 µg/L of mutagen NMU, sowing the xBrassicoraphanus seeds, gathering the xBrassicoraphanus seeds, sowing the xBrassicoraphanus seeds again, performing artificial crossing in an indoor area to check seed productivity, and checking the uniformity of the variety using an AFLP primer.本発明は、種子生産性が安定化された高妊性ラパノブラシカ新品種植物の育種方法に係り、突然変異誘発物質NMUを0.01μg/L処理してラパノブラシカ種子を突然変異処理して種まきして採種してまた種まき後室内で人工交配して種子生産性を確認して続いてAFLPプライマー(primer)を利用して品種の均一性を確認することを特徴とするラパノブラシカ新品種植物の育種方法を開示する。【選択図】図1
