摘　　要：冬小麦新品种静宁12号以旱大穗为母本,自育品系92品18为父本,通过有性杂交、多代集团混合选择技术选育而成。株高90~120 cm,穗长6.5~7.5 cm,结实小穗15~18个,穗粒数21~53粒,千粒重31.5~51.5g,容重784 g/L。含粗蛋白140.0 g/kg、赖氨酸3.9 g/kg、湿面筋222.0 g/kg,沉降值(14%水分基)25 m L,粗灰分(干基)18.3 g/kg,水分9.71%。条锈病2级,抗旱性2级,抗寒性2级,后期抗青干,为优质、抗病、抗旱的新品种。在2014—2015年度甘肃陇中片区域试验中,平均折合产量4 872.00 kg/hm^2,较对照品种陇中1号增产7.3%。适宜在甘肃平凉、定西等地年降水量200~500 mm、海拔2 600 m以下的干旱、半干旱区种植。Jingning 12 is a newly bred winter wheat culfivar by parental combination of Handasui with inbred line 92 Pinl8, and through sexual hybridization, used multi generation group hybrid selection technology. The result shows that the plant height is 90- 120 cm, ear length is 6.5 - 7.5 cm, solid spikelet is 15 - 18, the number of grains per spike is 21 ~ 53 grains, 1 000 grain weight is 31.5 - 51.5 grams, bulk density is 784 g/L, and the containing of crude protein is 140.0 g/kg, lysine is 3.9 g/kg, wet gluten is 222.0 g/kg, sedimentation value is 25 mL（water base is 14%） crude ash （dry base） is 18.3 g/kg, moisture content is 9.71%. The result indicates that the stripe rust is the grade 2, drought resistance is the grade 2, cold resistance is the grade 2, anti-dry at Later stage, it is a new cultivar with high quality, disease resistance and drought resistance of new eultivars. In the 2014 -- 2015, the average yield reaches 4 872.00 kg/hm2, which is 7.3% higher than that of the check Longzhong 1. It is suitable to be grown the arid and semi-arid areas of precipitation is 200 - 500 mm, with an elevation of less than 2 600 m in Gansu, Dingxi and other places .
