摘　　要：为了促进旱地春小麦新品种的更新换代,实现小麦抗旱、抗病、丰产、稳产,以定西35号为母本、甘春25号为父本进行杂交,采用系谱法选育出了旱地春小麦新品种会宁22号。该品种生育期107 d,株高115 cm,穗粒数31粒,千粒重48.8 g。在2019—2020年甘肃省旱地春小麦区域试验中,会宁22号平均折合产量3772.80 kg/hm^(2),较对照品种西旱2号增产7.58%;在2021年甘肃省旱地春小麦生产试验中,平均折合产量2733.00 kg/hm^(2),较对照品种西旱2号增产7.29%。该品种中熟,籽粒含蛋白质(干基)131.3 g/kg、湿面筋(14%水分基)301.0 g/kg,降落数值339 s,Zeleny沉淀值20.8 mL,吸水率63.6%,容重804 g/L。中抗条锈病、高抗白粉病。适宜在甘肃中部在甘肃中部干旱半干旱区的春麦区及类似生态区种植,尤其适合旱山塬地种植。To promote the renewal of new dryland spring wheat varieties and achieve drought resistance,disease resistance,high yield,and stable yield in wheat production,Huining 22,a new dryland spring wheat variety,was bred by crossing Dingxi 35 as the female parent with Ganchun 25 as the male parent using the pedigree method.This variety has a growth period of 107 days,a plant height of 115 cm,31 grains per spike,and a thousand-grain weight of 48.8 g.In the 2019 to 2020 Gansu Province dryland spring wheat regional experiment,the average yield was 3772.80 kg/ha,an increase of 7.58%compared to the control variety Xihan 2.In the 2021 Gansu Province dryland spring wheat production experiment,the average yield was 2733.00 kg/ha,an increase of 7.29%compared to the control variety Xihan 2.This variety is medium-maturing,with grain protein content(dry basis)of 131.3 g/kg,wet gluten(14%moisture basis)of 301.0 g/kg,falling number of 339 s,Zeleny sedimentation value of 20.8 mL,water absorption rate of 63.6%,and bulk density of 804 g/L.It has moderate resistance to stripe rust and high resistance to powdery mildew which is suitable for planting in the spring wheat areas of central Gansu's dry and semi-arid regions and similar ecological zones,especially suitable for dry plateau areas.
