The whole growth period of semi-winter mid-late maturity varieties is 23 1 day, which is later than that of the control zhoumai 18 1 day. The seedlings are semi-prone, grow vigorously, and the leaves are wide and dark green. Moderate cold resistance in winter. Strong tillering ability and moderate tillering rate. It develops quickly in early spring, gets up early at jointing stage, has fast polarization and late heading, and has moderate resistance to late spring cold. Good high temperature resistance and maturity in the middle and late stage. The plant height is 76 cm, the plant type is moderately elastic, the stem is stout and the lodging resistance is good. The ear layer is neat, and the flag leaves are wide and long. Spike spindle-shaped, short awn, white shell, white grain, half-angle plasmid, average fullness. The average yield per mu is 402,000 grains, 35.6 grains per ear, and the 1000-grain weight is 41.7g.. The inoculation identification of disease resistance showed that leaf rust, scab, powdery mildew and sheath blight were highly susceptible, and stripe rust was moderately resistant. According to the quality of the mixed sample, the bulk density is 8 10g/L, the protein content is 14.52%, the hardness index is 64.0, the wet gluten content of flour is 34. 1%, the sedimentation value is 36. 1ml, and the water absorption rate is 58./kloc.
Yield performance
20 10-20 1 1 participated in the regional test of winter water group varieties in the south of Huanghuai winter wheat area, with an average yield of 584. 1 kg, which was 3.9% higher than that of the control Zhou wheat 18. 20 1 1 ~ 20 12 continuous experiments showed that the average yield per mu was 5 10.3 kg, which was 5.3% higher than that of Zhoumai 18. The annual production test of 20 12 ~ 20 13 showed that the average yield per mu was 502.8 kg, which was 7.0% higher than that of Zhoumai 18.
