摘　　要：当归新品系DGA2000-02是采用重离子束55MeV/u40Ar+15离子辐照甘肃当归90-01干种子,按新品种选育程序多年选育而成的。2005—2007年,在定西市岷县、渭源县、漳县、陇西县等地当归品系区域试验中,甘肃当归DGA2000-02平均产鲜当归10621.5kg/hm2,较对照品种(甘肃当归90-01)平均增产鲜当归1386.0kg/hm2,增产率15.0%。生育期790d,茎秆深紫色,根系黄白色。测定结果:总灰分4.2%,酸不溶性灰分0.4%,分别优于对照品种16%和33.3%;浸出物61.4%,较规定指标提高4.4%;阿魏酸0.148%,较规定指标提高2.96倍。质量显著优于对照品种和2005年版《中国药典》规定指标。适宜在海拔2000—2600m、年降水量500—600mm的二阴及高寒阴湿生态区栽培。Angelica sinensis （Oliv）Diels new strain DGA2000-02 was selected successfully by Institute of Modern Physics, Chinese Academy of Sciences, Dryland Farming Research and Extension Center of Dingxi Prefecture, etc. According to the program of new strain selection, this new strain was selected for several years after the dry seeds of Gansu Angelica sinensis（Oliv）Diels 90-01 was irradiated by ions of 55 MeV/u ^40Ar^＋15. During the period of year 2005-2007, region experiments of Angelica sinensis （Oliv）Diels new strain DGA2000-02 were developed in Minxian, Weiyuan, Zhangxian and Longxi etc. Average yield of the fresh DGA2000-02 Angelica was 10 621.5 kg/hm^2 , and 15.0% production was increased more than control （for 1 386.0 kg/hm^2 of 90-01）. The growth stage of the DGA2000-02 was 790 d, and it has deep purple stem and yellow-white root. The quality analysis results are as follows： total ash content is 4.2 % and acidfast ash content is O. 4%, 16% and 33.3% better than control, respectively; the lixivium is 61.4%, i. e. , 4.4% more than the standard of Pharmacopoeia of People＇s Republic of China （2005 edition） ; the ferulic acid content is 0. 148%, i. e. , 2.96 times ligher than the standard. All these results showed that the quality of the DGA2000-02 was better significantly than both control and the standard. It can be grown appropriately at the high, cold and dankness regions at the altitude of 2 000-2 600 m and with a annual precipitation of 500-600 mm.
