The seedling is semi-erect, the leaf is wide, the growth is prosperous, the leaf color is thick green, and the cold resistance in winter is general. The tillering ability is medium and the panicle rate is high. Early jointing in spring, fast polarization, and general ability to withstand the cold in spring. The root system has strong activity, high temperature tolerance in the later stage, quick filling and good ripening phase. The plant type is slightly compact, the plant height is 78.8 cm, the stem elasticity is medium, and the lodging resistance is weak. The flag leaves are wide and long and draped at the bottom. The ear is spindle-shaped, the ear layer is thick, long awn, white shell, white grain, grain half-horny, medium plumpness.

Disease resistance identification, high resistance to stripe rust, moderately susceptible leaf rust, highly susceptible powdery mildew, scab, sheath blight. Quality testing showed that the grain bulk density was 788 g / L, the protein content was 14.55%, the wet gluten content was 30.6%, the sedimentation value was 19.9 ml, the water absorption was 53.7%, the stability time was 1.2 minutes, the maximum tensile resistance was 127E.U., the extensibility was 133 mm, and the stretched area was 20 square centimeters.

Second, yield performance

In the 2012-2013 regional trial of Chunshui group varieties in the southern part of Huang-Huai winter wheat region, the average yield per mu was 472.8 kg, 6.0% higher than the control variety Yanzhan 4110, and the average yield per mu was 561.3 kg, 6.9% higher than Yanzhan 4110. In the production test from 2014 to 2015, the average yield per mu was 525.9 kg, which was 7.3% higher than that of Yanzhan 4110.
