[Abstract]
Tianxuan 54, a new-bred winter wheat cultivar systematically by crossing with the parental combination of Wenmei 8/9157-3-2-2-1. The average yield of Tianxuan 54 is 6 414.0 kg/hm2 and 5.17% higher than of the check in winter wheat regional test which is conducted during the period 2011 — 2013 in the Longnan district. In 2013 — 2014, the average yield of Tianbxuan 54 is 6 120.0 kg/hm2 and 7.90% higher than of the check in wheat produce test. In addition, the plant heigth is 80.00 cm, ear length is 8.50 cm, thousand grain weight is 41.25 g, bulk weight is 756.2 g/L, seed crude protein is 141.2 g/kg, wet gluten is 267.2 g/kg settlement value of 26.5 mL. By inoculating indentification,the resut shows that Tianxuan 54 is 2/10/60 to mixture race at the seeding stage, immune completely to Shui4、 Gui22-14、 Gui22-9、 CY32、 CY33 and mixture race at the adult stage. It is suitable to be grow in the vally area of Tianshui city and Longnan city.
