摘　　要：水芹(Oenanthe javanica(Blume)DC.)雄性不育材料在水芹杂交育种中具有重要作用。本研究描述了一种雄蕊退化的水芹雄性不育材料(OJBY001)。该材料的特征为:侧枝多、叶片及叶柄深绿色,花丝萎缩和花药干瘪、柱头伸长、能够分泌蜜液及接收外来水芹花粉,隶属于水芹种。相较于可育水芹(OJKY002),OJBY001在茎和叶柄中的干物质极显著高于OJKY002,以及走茎中的维生素C、可溶性糖及类黄酮含量显著或者极显著高于OJKY002中的含量。Male sterility plays an important role in the hybrid breeding of water dropwort(Oenanthe javanica(Blume)DC.).In the current study,a male-sterile water dropwort(OJBY001)with a degenerated stamen was described.OJBY001 was characterized by many lateral branches,dark green leaf blades and petioles,atro-phic filaments and anthers,elongated stigma,and the ability to secrete nectar and receive exotic pollen from other water dropwort belonging to O.javanica.Compared to fertile water dropwort(OJKY002),OJBY001 ex-hibited significantly higher stem and petiole dry matter and and significantly or extremely significantly higher contents of vitamin C,soluble sugar,and flavonoids in the stolon.
