In addition, the plant heigth is 82-95 cm, ear length is 8.0-8.3 cm, thousand grain weight is 42~43 g, bulk weight is 780-802 g/L, seed crude protein is 12.16%, wet gluten is 23.0% and settlement value of 21.3 mL. By inoculating indentiIieation, the result showed that Tianxuan 47 was 0; -2/10/10 to mixture race at the seeding stage and immune completely to Shui 14, CY 32, Shui 4, CY 32, CY 29 at the adult stage. It is suitable to plant in terrace of semi-mountainous and secendary humid areas of north-south in the district of 1 800 m above sea level of Tianshui city.
