摘要 冬小麦新品系陇育0024是陇东学院农林科技学院以西峰27号作母本,89-235-11-2-1作父本进行有性杂交选育而成。2010-2012年参加甘肃省(陇东片)冬小麦区域试验,平均折合产量5019.45 kg/hm2,较对照品种西峰27号增产6.31%;2012-2013年度参加甘肃省(陇东片)冬小麦生产试验,平均折合产量3421.95 kg/hm2,比对照品种西峰27号增产6.00%,居参试3个品种(系)的第1位。抗寒性1~2级,抗旱性1~2级,抗青干1级,落黄1级;总体抗锈性表现较好,病情指数在20%以下,具有慢条锈特性。籽粒含粗蛋白质15.25%(干基)、湿面筋32.4%(14%湿基),沉降值29.2 mL、吸水率62.8%,面团形成时间2.7 min,稳定时间1.7 min。适宜在甘肃庆阳、平凉及宁夏固原等地区山塬旱地及同类地区种植。 Longyu 0024 was a new winter wheat line bred by crossing the female parent Xifeng 27 and the male parent 89-235-11-2-1 in College of Agriculture and Forestry,Longdong University . Compared with that 4 862.85 kg/hm2 of Xifeng 27,the average yield of Longyu 0024 increased by 6.31%and reached 5 019.45 kg/hm2 in 2011-2012 Gansu (Longdong region)winter wheat regional test . Its average yield was 3 421.95 kg/hm2 and 6.00%highest among all the tested samples,which was higher than Xifeng 27 in 2013 in Longdong region winter wheat production test. The cold,drought resistance,antigreen- dry and yellowing is 1-2 grade, 1-2 grade, 1 grade and 1 grade, respectively. It has a overall resistance performance of disease index below 20% and the slow embroidered characteristics . The grain contains the crude protein of 15.25%(dry basis), wet gluten of 32.4%(14% wet basis). It has a sedimentation value of 29.2 mL,water absorption rate of 62.8%,dough development time of 2.7 min and stability time 1.7 min .. Longyu 0024 is suitable for planting in the arid mountain plateau and other similar areas in Gansu, Qingyang and Pingliang, Ningxia,Guyuan .
