摘要
冬小麦新品系陇麦898是利用染色体工程技术,结合常规育种方法,以"三抗一丰一优"为总体育种目标,联合选育而成的中早熟冬小麦新品系。2005—2007年参加平凉市山塬组冬小麦区试,2 a 12点(次)平均折合产量4 871.55 kg/hm2,较对照品种兰天10号增产15.13%,居11个参试品种(系)的第1位;2006—2008年参加甘肃省陇东片冬小麦区试,2 a 9点(次)平均折合产量3 423.75 kg/hm2,较对照品种西峰20号增产4.19%,居11个参试品种(系)的第5位。该品系株高85 cm,平均穗长5.6 cm,平均小穗数15.8个,平均穗粒数33.6粒,平均千粒重48.9g,容重784 g/L。籽粒含粗蛋白108.7 g/kg(干基)、赖氨酸4.04 g/kg(干基)、湿面筋184.7 g/kg(14%水分基)、淀粉值32.5 mL(14%水分基)。抗旱抗冻,高抗条锈病,高产稳产,适应性强;分蘖成穗率高,群体结构好。适宜在甘肃省陇东山塬旱地、高寒阴湿山区和丘陵干旱山区,以及陕西省陇县,宁夏固原等周边类似地区种植。
Longmai 898 was a new middle early mature winter wheat strain, which bred by chromosome engineering and normal breeding technology, its breeding objective is to select high yield, good quality and three resistances characteristics. In 2005-2007, the yield of this strain was highest among 11 varieties （strains） in two year in twelve points （times） test in winter wheat mountain-plateau region of Pingliang, the average yield is 4 871.55 kg/hm^2 and 15.13% higher than the control Lantian 10. In 2006--2008, the yield ranked fifth in 11 varieties （strains） in two years in nine points （times） in winter wheat region test of Longdong, the average yield was 3 423.75 kg/hm^2 and 4.19% higher than the control Xifeng 20. The plant height, spike length, number of spikelet, grain number, thousand grain weight and bulk density of this strains are 85 cm, 5.6 cm, 15.8 seed, 33.6 seed, 48.9 g and 784 g/L, respectively. The results indicated that the seed crude protein grain, lysine, wet gluten, sedimentation values are 108.7 g/kg, 4.04 g/kg, 184.7 g/kg and 32.5 mL, respectively. Longmai 898 was strong drought and frost resistance, as well as stripe rust resistance, higher and stable yield, widely adaptability. The tiller earing rate and population structure are better than the other varieties or strains. It is suitable to plant in rain-fed area on loess plateau, high-altitude mountainous areas, hilly and arid mountain area of Longdong region in Gansu province, Longxian county in Shaanxi, Guyuan county in Ninxia and other similar areas.
