Abstract：Zhengmai 7698 is a new wheat variety with high quality and high yield characteristics.In this paper the quality characteristic of Zhengmai 7698 located in Henan fourteen prefecture-level cities were investigated to determine its quality stability.Efficient cultivation techniques were established by investigating yield effect of Zhengmai 7698 under different sowing time,sowing density and fertilization regimes levels.The quality stability research results showed that quality characters of Zhengmai 7698 reached national high quality and strong gluten standards in Henan province except western infertile area.The cultivation experiments results showed that its suitable sowing time in Henan was October 10th to 20th,and the suitable sowing rate was 187.5 kg/ha.The optimal fertilizer manner was 225.0 kg/ha urea + 375.0 kg/ha diammonium phosphate as base fertilizer and 112.5 kg/ha urea as topdressing in northern Henan,and 225.0 kg/ha urea + 375.0 kg/ha diammonium phosphate as base fertilizer and 150.0 kg/ha urea as topdressing in other areas.
