Abstract: By analyzing and comparing with the compared varieties, we get the conclusion that winter wheat varieties named Qingnong in Longdong increased 1.2%~24% in yield, 0.08%~1.89% in protein content, 0.13%~0.22% in lysine content, and enhanced in disease-resistance and draught-resistance, but reduced 5-10cm in height of wheat. We find it crucial to choose the varieties fit for the local condition as one of the parent generations; to choose varieties directionally for draught-resistance, cold-resistance and early ageing-resistance from F1 to Fn; to guarantee and improve enough grain ears, grains per ear and grain weight and coordinate them. In future, we will continue selecting high quality variety for special purpose, increasing grains per ear and grain weight as possible as we can, coordinating high yield and stable yield.
