Analyze and Evaluate Quality Characters of Winter Wheat in Xinjiang

In this paper ,thirteen quality characters of 47 different reign of winter wheat were analysed.The result show that the protein content?wet gluten content?sedimentation value of varieties of Xinjiang are less than them of varieties of other province,but developdent time?stability time?degree of softening?maximum resitence extensibility is opposite.compared with foreign varieties,the protein content?wet gluten contenet and flour yield of varieties of Xinjiang are higher,but some important quality characters(e.g.sedimentation value?development time?stability time?evaluation value and degree of softening) are lower.Quality type of Xinjiang varieties are mostly belong to middle-quality varieties.hower,there are some excellent varieties,such as XinDong23 being with the best performances in some important quality characters.Correlation analysis show that there is significantly positive relationship between sedimentation value and dough developmen time?stability time?maximum resistence extensibility?evaluation value,and significantly negative relationship to wet gluten content and degree of softening,but no significant relationship between sedimentation value and the other characters.
