Abstract:Longmai 479 is a new winter wheat cultivar, bred by using pedigree method for directional selection in water and drought, with combination of Changwu 134 as the female parent and TW98-829-1 as the male parent. In 2017 — 2019, the average yield was 5 235.00 kg/hm2, 13.6% higher than that of the control Longyu 4 in East Gansu Winter Wheat Regional Test. The plant height is 78.0 cm, the 1000-grain weight is 42.0 g and the bulk density is 800.0 g/L. The average of panicle length, spikelets number, grains per spike number and panicle number are 7.6 cm, 15.2, 34.0, 345,000 panicles, respectively. The crude protein content is 162 g/kg(dry base), lysine content is 3.6 g/kg, wet gluten content is 374 g/kg(14% moisture base), precipitation value is 44.0 mL (14% moisture base), total ash content is 130 g/kg, water content is 93.6 g/kg. This cultivar high-yield and stable-yield, widely suitable for water saving, neat panicle layer, good ripening, which was strong resistance to stripe rust, medium resistance to leaf rust and powdery mildew, good resistance to cold and drought, strong resistance to spring cold. It is suitable to be grown in the East of Gansu Province, Changwu, Ganxian and Binxian of Shaanxi Province, Guyuan of Ningxia and dry and fertile land and water platform of other similar ecological areas.

冬小麦是陇东地区的主要粮食作物,年种植面积33.3万hm2,该区气候复杂、生态多样,灾害频发,小麦产量低不稳,种植效益低[1 - 4 ]。为此,平凉市农业科学院小麦育种创新团队,针对陇东旱寒多病的自然生态条件,经多年努力,以“三抗一丰、三省一广”为育种目标,联合攻关,穿梭选育,选育出冬小麦新品种陇麦479。2021年3月通过甘肃省农作物品种审定委员会审定定名(审定编号:甘审麦20210026)。

1   亲本来源及选育经过

陇麦479以长武134作母本、自育中间材料TW98-829-1作父本进行有性杂交,经系谱法水旱穿梭联合选育而成,原系谱号TW06-479。长武134是陕西省长武县农业技术推广中心育成的强抗旱适应性广的旱肥地与半水地品种,通过省级和国家级审定,冬性,抗冻,抗旱,抗倒伏,大穗大粒,抗条锈,中抗白粉、叶锈,中熟。……
