摘　　要：冬小麦新品种武都19号以97-4-6-2-1-2为母本、98SF531-1-4-1(92R178/D599)为父本杂交,采用系谱法选育而成。在2013—2015年甘肃省陇南片川区组区域试验中,2 a 12点(次)平均折合产量6766.5 kg/hm2,较对照品种兰天25号增产9.4%。在2015—2016年度甘肃省陇南片川区组生产试验中,平均折合产量5653.5 kg/hm2,较对照品种兰天25号增产5.3%。生育期247 d,株高103.5 cm,穗长9.1 cm,穗粒数45.2粒,千粒重42.2 g。籽粒含粗蛋白(干基)152.7 g/kg、粗灰分(干基)24.5 g/kg、湿面筋287.5 g/kg、赖氨酸3.91 g/kg,沉淀值43.5 mL,容重805.5 g/L。经接种鉴定,苗期对混合菌表现免疫,成株期对供试菌系条中32号、水4、贵22-9及贵22-14及混合菌表现免疫,总体抗性表现优异。可在陇南市半山干旱、半干旱区、徽成盆地及低半山河谷川台地区和天水市甘谷、清水、麦积等地区种植。Wudu 19 is a new winter wheat cultivar,bred by pedigree method with 97-4-6-2-1-2 as female parent and 98SF531-1-4-1(92R178/D599)as male parent.In 2013—2015,the average yield in 2 a 12 sites(times)was 6766.5 kg/hm2 and 9.4%higher than that of the check Lantian 25 in South Gansu Regional Trial.In 2015—2016,the average yield was 5653.5 kg/hm2,which was 5.3%higher than the control Lantian 25 in Gansu South Regional Trial.The growth period is 247 d,plant height is 103.5 cm,ear length is 9.1 cm,ear grain number is 45.2,1000-grain weight is 42.2 g.The crude protein(dry basis)of grain is 152.7 g/kg,crude ash(dry basis)is 24.5 g/kg,wet gluten is 287.5 g/kg,lysine is 3.91 g/kg,sedimentation value is 43.5 mL and bulk weight is 805.5 g/L.By inoculation and identification,it was immunity to mixed bacteria at seedling stage,and immunity to tested strains CY 32,Shui 4,Gui 22-9,Gui 22-14 and mixed bacteria at adult stage,overall resistance was excellent.It can be planted in mid-mountain arid,semi-arid area of Longnan City,Huicheng basin and low-mid-mountain valley area and Gangu,Qingshui and Maiji areas of Tianshui City and other areas.
