国家水生蔬菜金华育种创新基地特色品种选育

Breeding of Special Varieties in National Aquatic Vegetable Jinhua Breeding Innovation Base

自2000年以来,金华市农业科学研究院围绕产业发展需求,不断开展水生蔬菜种质资源收集与创新,建成了国家水生蔬菜育种创新基地,构筑了约6.67 hm2的现代化种质保存和育种试验平台;收集保存了特色水生蔬菜遗传资源500余份,重点保育了金华白莲、西湖莼菜等濒危珍贵地方资源13份;拓展了水生蔬菜海南南繁加代、定向杂交、理化诱变等育种技术新路径,填补了种质鉴定和评价利用技术参数空白,制订了农业部行业标准;育成了茭白‘浙茭3号’、鲜食籽莲‘金芙蓉1号’、藕莲‘东河早藕’等高产优质特色新品种,为浙江乃至长江中下游水生蔬菜品种更新作出了一定贡献。

According to the industrial development demands, aquatic vegetable germplasm resources were collected and innovated from 2000, the national aquatic vegetable breeding innovation base was established, modern germplasm conservation and breeding experimental platform a-bout 6.67 hm2 was constructed; more than 500 characteristic aquatic vegetable germplasm resources were preserved, 13 endangered and rare local resources such as Jinhua white lotus and West Lake water shield were key protected;breeding new technology was expanded such as off-season breeding in Hainan, directed hybridization, physical and chemical mutagenesis, the blank of germplasm identification and evaluation and utilization of technical parameters was filled, the sector standard was formulated; new varieties with high yield and high quality such as water bamboo Zhejiao No.3, fresh lotus seed Jinfurong No.1, lotus root Donghe Zaoou were obtained, which made a certain contribution to a-quatic vegetable varieties updating in Zhejiang and the middle and lower reaches of the Yangtze River .
