摘　　要：春小麦新品种陇春28号是甘肃省农业科学院作物研究所以自育品系9807-2-14为母本,以从CIM-MYT引进的"CM7033"和"CM7015"为父本复合杂交选育而成。在2009—2010年甘肃省水地春小麦(东片)10点(次)的区域试验中,折合产量5 205.2 kg/hm2,较对照陇春23号增产6.51%,居参试品种(系)第1位。该品种株高75～80 cm,穗长8.5～9.2 cm,千粒重42.8～46.6 g,容重754～795 g/L,生育期92～105 d。籽粒含粗蛋白13.06%(干基),湿面筋29%,降落值382 S,Zeleny沉降值38.2 mL,面团形成时间3.3 min,稳定时间3.6 min。经鉴定,苗期对混合菌表现感病,成株期对供试菌系水4、水7、HY8表现抗病,对条中32号、条中33号及混合菌表现中抗。适宜在甘肃中部沿黄灌区、高寒阴湿区和二阴地区及生态条件相似地区种植。Longchun 28 was a new spring wheat variety bred systematically by crossing with the parental combination of self-bred line 9807-2-14/ CM7033//CM7015,which come from CIMMYT.The average yield of Longchun 28 was 5 205.2 kg/hm2 and 6.51% higher than of the check Longchun 23 in spring wheat regional test during the period 2009-2010 in eastern waterland of Gansu provice.In addition,the plant height is 75～80 cm,ear length is 8.5～9.2 cm,1000-grain weight is 42.8～46.6 g,bulk weight is 754～795 g/L,growing period is 92～105 d.The results showed that seed crude protein,wet gluten,sedimentation value,developing and stability time were 13.06%,29.0%,38.2 mL,3.3 min and 3.6 min.By inoculating identification,the results also showed that longchun 28 was resistance to Shui 4,Shui 7,HY 8 and moderate-resistance to CY 32,CY 33 and mixture race at the adult stage.It is suitable to plant in middle Gansu irrigation areas along the Yellow River of Central Gansu,cold and humid region,Semi-arid region and ecological conditions similar areas.
