[Abstract]
Longmai 079 is newly bred winter wheat cultivar by parental combination of Lumai 1 with TW98-829-1 by Institute of Crop, Pingliang Academy of Agricultural Sciences, used pedigree method and bred between water and dry land. In 2011 — 2013, the average yield reaches 4 930.50 kg/hm2, which is 9.23% higher than that of the check Xifeng 27 in the Winter Wheat Regional Test of Longdong region of Gansu province; In 2013 — 2015, the average yield reaches 4 990.42 kg/hm2, which is 8.68% higher than that of the check Longyu 4 in the Winter Wheat Production Test of Longdong region of Gansu province. The result shows that plant height is 95.8 cm, spike length is 6.5 cm, the average spikelet number is 16.0, the average kernels is 37.2, and the thousand kernel weight is 40.8 g, the bulk density is 785.0 g/L. The content of crude protein is 121.7 g/kg(dry base), lysine content is 4.07 g/kg(dry), wet gluten content is 202.4 g/kg(14% moisture), and the sedimentation value is 27.1 mL (14% moisture). The result indicates that new cultivar resists frost and drought, strong stress resistance, wide adaptability and water-saving, resists to lodging, high spike rate, compact plant type, neat spike layer, high and stable yield. It is suitable to be grown in the most of arid mountain, plateau, hilly, wet and dank mountainous in Eastern of Gansu, Changwu and Longxian of Shanxi province, and other similar ecological planting areas of Guyuan in Ningxia.
