Zhenmai 168

Characteristics: spring, the whole growth period is about 208 days, which is equivalent to the control Yangmai 158. The seedlings are semi-erect, the leaves are light green, the tillering ability is medium, the polarization is faster, and the panicle rate is higher. The plant height is about 85 cm, the plant type is semi-compact and the ear layer is neat. Spike spindle type, long awn, white shell, red grain, keratin, fuller. The average number of ears per mu is 336000 ears, the number of grains per ear is 35.1 grains, and the weight of 1000 grains is 40.4g. The cold resistance is similar to that of the control, the lodging resistance is stronger, and the ripening phase is good. Identification of disease resistance: medium resistance to scab, sheath blight, slow leaf rust, moderately susceptible stripe rust, moderately to highly susceptible stem rust, highly susceptible powdery mildew. In 2005 and 2006, the mixed samples were determined: bulk weight 801g / L, 797g / L, protein (dry base) 14.73,14.02%, wet gluten 33.0%, 28.2%, sedimentation value 48.8ml, 47.5ml, water absorption 60.6%, 60.8%, stability time 9.3min, 10.9min, maximum extension resistance 453E.U, 433E.U, extensibility 16.7cm, 15.5cm. The stretched area is 102.4 square centimeters and 90.4 square centimeters.

Yield performance: participated in the regional trial of winter wheat varieties in the middle and lower reaches of the Yangtze River from 2004 to 2005, the average yield per mu was 395.4 kg, which was 0.31% higher than that of Yangmai 158, which was 0.31% higher than that of Yangmai 158. The average yield per mu was 392.1 kg, which was 0.58% higher than that of Yangmai 158. In the production test from 2006 to 2007, the average yield per mu in Hubei, Anhui, Jiangsu and Zhejiang provinces was 410.3 kg, which was 4.83% higher than that of Yangmai 158, and the average yield per mu in Xinyang, Henan was 515.8 kg, 6.2% higher than that of Yumai 18.

The key points of cultivation techniques are as follows: the suitable sowing date is from late October to early November, and the suitable basic seedlings are 150000 ~ 180000 seedlings per mu. Increase the application of phosphorus and potassium fertilizer, reasonable operation of nitrogen fertilizer, give full play to its advantage of strong gluten quality. Pay attention to the prevention and control of powdery mildew, leaf rust and other diseases.
