Jingmai 4 is a newly winter wheat variety by parental combination of D5003-1 with RAH122 by Jingning Seed Management Station,(D5003-1/RAH122)F1 as female,D282 as male parent after the second hybridization in the next year. The result shows that the plant height is 90~105 cm,the ear length is 6.8~8.0 cm,grain number per spike is 40~45 grain,1 000 grain weight is 43.0~47.5 g,bulk density is 759.0 g/L;grain crude protein is 150.6 g/kg(dry basis),wet gluten is 272.0 g/kg(14%water base),lysine acid is 4.57 g/kg(dry basis),sedimentation value is 31.8 mL(14%water base)value . It is resistant to cold,drought resistance,stable and good stability,immunity to stripe rust,powdery mildew. The average yield of 4 658.9 g/hm2,which is 14.13%higher than of the check in the Gansu area test conducted in the period 2008—2009. It is suitable to be grown in Jingning county,Zhuanglang county, Tongwei county,Longxi county,Anding district of Gansu province and Xiji county,Longde county,Yuanzhou district of Ningxia Hui Autonomous Region with similar ecological condition.
