Breeding unit: Department of Agronomy, Shandong Agricultural University.

Approval: approved by Shandong crop Variety approval Committee, Jiangsu crop Variety approval Committee in 1996, and the National crop Variety approval Committee in 1998.

Variety approval number: national examination and approval wheat 980010.

Variety source: (Tal Yangmai 1 BI/757318) FI//104-14.

Characteristics: semi-winter spring. The plant height is 80-85 cm, the ear is approximately rectangular, the number of ears per mu is 350000-380000 ears, the 1000-grain weight is about 43 grams, the crude protein content is 13.2%, and the bulk weight is 771g / liter. Mid-early maturing varieties are resistant to stripe rust, leaf rust and stem rust, susceptible to powdery mildew, and have good resistance to soil-borne mosaic disease. The three factors of yield are more coordinated, high yield and stability, dry and hot air resistance, good ripening phase. From 1987 to 1989, he participated in the regional test of the high fertilizer group in Shandong Province. The average yield per mu in two years was 483.5 kg, which was 8% higher than that of Jinan 13, which was 8% higher than that of Jinan 13. In 1989-1990, the average yield per mu was 427kg, 19.7% higher than that of Jinan 13. From 1993 to 1996, he participated in the regional test and production test of wheat in Jiangsu Province, with an average yield of 429 kg per mu.

Cultivation points: generally, it is appropriate to sow seeds from October 1st to Cold Dew, and late sowing can be postponed to the first or middle of November. Under the condition of high fertilizer and water, the basic seedling per mu is 810,000-100,000 ears, and under the condition of medium fertilizer and water, the basic seedling per mu is 120,000-150000. Pay attention to the control of powdery mildew and sheath blight.

Suitable range: middle and upper fertility areas of central and southern Shandong and northern Jiangsu.
