【摘要】 46年来,共育成浙农系列茶树新品种8个,其中包括国家级良种2个(浙农12、浙农113),省级良种3个(浙农121、浙农21、浙农25),待审定品种3个(浙农23、浙农117、浙农139);选育出杂交新品系20个:同时,对主要经济性状的早期鉴定、部分性状的遗传动态、茶树再生系统建立和遗传转化等进行了研究并取得重要成果。最后,总结出四点体会:一是茶树育种成败首先取决于是否能正确选用种质资源:二是必须深入开展早期鉴定研究;三是推广茶树良种必须与开发良种名茶相结合;四是必须加强育种理论与育种新技术的研究。更多还原

【Abstract】 During the past 46 years, eight Zhenong series new tea cultivars were bred including two national level registered tea cultivars (Zhenong 12, Zhenong 113), three provincial level registered tea cultivars (Zhenong 121, Zhenong 21, Zhenong 25), three cultivars were ready for registration ( Zhenong 23, Zhenong117, Zhenong 139), 20 new hybrid lines were selected and bred. Besides, the early stage evaluation of major economic characters, the genetic dynamics of some characters, the establishment of regeneration system of tea plant and the genetic transformation were investigated and some important achievements were obtained. Finally, the following four points were summed up: 1. The success or failure of tea breeding are mainly depended on the correct selection of germplasm. 2. The thorough investigation on the early-stage evaluation is needed to be conducted. 3. The widespreading of registered tea cultivars is recommended to combine with the development of famous tea. 4. The investigation on the tea breeding theory and new breeding technique must be strengthened.更多还原
