摘要
陇谷15号是甘肃省农业科学院作物研究所杂粮室2002年以晋谷29号做母本、以陇谷9号做父本进行杂交,经过多年水旱穿梭选育和多点鉴定育成的丰产、抗病、优质谷子新品种。陇谷15号生育期120~128 d,株高133.3 cm,茎粗0.70 cm,主茎可见节数10.4节,穗长24.05 cm,单株穗重17.66 g,单穗粒重12.80 g,千粒重2.31 g,单株草重23.35 g,出谷率72.48%。经甘肃省农业科学院农业测试中心检测,籽粒含水分103.7 g/kg(干基)、粗蛋白147.4 g/kg(干基)、粗脂肪50.7 g/kg(干基)、粗淀粉666.1 g/kg(干基)、赖氨酸3.0 g/kg(干基)、铁46.1 mg/kg(干基)。人工接种鉴定,陇谷15号黑穗病发病株率4.23%,表现为高抗黑穗病。
Longgu 15 a newly bred foxtail millet cultivar with high and stable yield and high resistance to smut by parental combination of Jingu 29 with Longgu 6 by Institute of Crops, Gansu Academy of Agricultural Science, used pedigree method and bred between water and dry land. The result shows that Longgu 15 have biological characteristics with growth period is 120-128 d, plant height is 133.3 cm, main stem diameter is 0.70 cm, main stem node number is 10.4, main panicle length is 24.05 cm, spike weight per plant is 17.66 g, grain weight per plant is 12.80 g, 1 000 grain weight is 2.31 g, straw weight per plant is 23.35 g, percentage of grain weight per spike is 72.48%. By testing in the Agricultural Testing Center of Gansu Academy of Agricultural Science, Longgu 15 grain moisture content is 103.7 g/kg, crude protein content is 147.4 g/kg, crude fat content is 50.7 g/kg, starch content is 666.1 g/kg, lysine content is 3.0 g/kg, iron content is 46.1 mg/kg. The result of artificial inoculation shows that the incidence rate of smut disease is 4.23%, it is high resistance to smut disease.
