Octoploid tritielytrigia type TAI-7045 showed immunity to yellow rust and middle resistance powdery mildew. CH-9916 is immune to yellow rust in seedling and adult stages, powdery mildew in seedling and adult stages, and their powdery mildew middle resistance. These suggested that the high powdery mildew-resistance in Octoploid tritielytrigia TAI-7045 had probably been transferred into common wheat.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
