为提高白银市春小麦单产，实现小麦生产可持续发展，选育和推广丰产性好、抗旱性强、适宜性广的优质春小麦新品种势在必行。白银市农业科学研究所以自育品系0636为母本、西旱1号为父本配制杂交组合，经多年系谱选择选育出旱地春小麦新品种银春11号。在2016 — 2017年的甘肃省旱地组春小麦区域试验中，银春11号2 a 10点(次)平均折合产量为2 810.4 kg/hm2，较对照品种西旱2号增产11.60%。在2018年的甘肃省旱地组春小麦生产试验中，银春11号平均折合产量为2 107.1 kg/hm2，较对照品种西旱2号增产10.10%。银春11号籽粒蛋白质(干基)含量154.7 g/kg，降落值118 s，湿面筋(以14%水分计)含量336.0 g/kg，赖氨酸(干基)含量4.6 g/kg，容重801.00 g/L。该品种抗旱性较好，中抗条锈病，适应性较好，成熟落黄好，适宜在甘肃中部干旱半干旱地区及生态条件相似的周边地区种植。

To improve the spring wheat yields in Baiyin and to achieve sustainable development in wheat production, it is vital to breed and to promote superior spring wheat varieties with high yield potential, strong drought resistance and ideal adaptability. Baiyin Institute of Agricultural Sciences carried out hybridized combinations using self-bred line 0636 as female parent and Xihan 1 as male parent, a new dryland spring wheat variety Yinchun 11 was bred by through years' pedigree selection and breeding. In the regional trial for dryland spring wheat from 2016 to 2017, the average yield was 2 810.4 kg/ha(data from 10 sites in 2 a), which was 11.60% higher than that of the control variety Xihan 2. In the production trial for dryland spring wheat carried out in 2018, the average yield was 2 107.1 kg/ha which was 10.10% higher than that of the control variety Xihan 2. Seed crude protein content was 154.7 g/kg (dryweight), falling number was 118 s, wet gluten (calculated as 14% of moisture content) was 336.0 g/kg, lysine content was 4.6 g/kg and seed density was 801.00 g/L. This new variety showed ideal performance in drought resistance and suitability, it is moderately resistant to strip rust disease with good mature color and is recommend for arid and semi-aridregions in central Gansu as well as other regions with similar environment.
