摘　　要：冬小麦新品种灵台4号是以兰天10号作母本,95-3-5作父本进行有性杂交,经过多年连续自然淘汰和人工选择选育而成。2011—2013年在甘肃省陇东片区域试验中,2 a共有8个点(次)增产,平均折合产量4 846.95kg/hm2,比对照品种西峰27号增产7.37%,产量居8个参试品种(系)第6位。2011—2012年度在灵台什字全膜覆土穴播示范片,产量高达8 422.50 kg/hm2。株高85 cm,穗长6.6 cm,千粒重42.5 g,容重762.9 g/L,生育期285 d,属中熟品种。籽粒含粗蛋白(干基)135.0 g/kg,湿面筋209.2%,沉降值19.7 m L,粗淀粉(干基)656.3 g/kg,灰分(干基)16.1%,属强筋小麦。综合抗病性好,条锈免疫,轻感白粉病,抗寒、抗旱性强,抗倒伏。适宜在陇东冬麦区的平凉市、庆阳市山塬旱地及周边同类地区种植。Lingua 4 is a newly bred winter wheat variety by parental combination of lantian 10 with 95-3-5 after many years of continuous selection. The average yield of two years of Lingtai 4 the variety reaches 4 846.95 kg/hm^2, which is 7.37% higher than that of the check Xifeng 27 in the regional test conducted in the period 2011 --2013, the production is the sixth. The yield of production reached 8 422.50 kg/hm^2 in the period 2011 --2012 in Demonstration area of Lintao county. The result shows that plant height, panicle length, 1 000-grain weight, bulk density, growth period are 85 cm, 6.6 era, 42.5 g, 762.9 g/L, 285 d, respectively, it is the middle maturing varieties. The result also indicates that seed crude protein （dry basis）, wet gluten, sedimentation value, crude starch （dry basis）, ash （dry basis） are 135.0 g/kg, 209.2%, 19.7 mL, 656.3 g/kg, 16.1%, respectively. In addition, Lingtai 4 is assume good resistant to diseases, immune to stripe rust, light susceptible to powdery mildew, good resistance to rust, and resistance cold, resistance drought, resistance lodging. It is suitable to be grown in the winter wheat area of arid mountain plateau of Pingliang, Qingyang of Gansu, and other similar areas.
