Tianxuan 51 is a newly bred systematically winter wheat variety by parental combination of 9362-13-4-4 with Lantian 1.The average yield of Tianxuan 51 reaches 6 600.00 kg/hm2, which is 8.65% higher than that of the check in winter wheat regional test conducted in the period 2008 — 2009、 2009 — 2010 in the Longnan district . In addition, the plant height is 90.4 cm, ear length is 7.12 cm, thousand grain weight is 43.9 g, bulk weight is 834.1 g/L, seed crude protein is 135.9 g/kg, wet gluten is 236.0 g/kg settlement value is 41.75 mL . By inoculating identification, the results shows that Tianxuan 51 was immune completely to mixture race at the seeding stage, immune completely to CY32、 CY33、 Shui4、 Shui5、 CH42、 HY8E and mixture race at the adult stage . It is suitable to be grow in the valley area of Tianshui city and Longnan city .
