The main results are as follows: (1) Variety source: it was selected by Neijiang Institute of Agricultural Sciences in 1988 with Kengui 1 V.P.M and Mianyang 14 as the main parents.
(2) characteristics: this variety is a spring variety with a full growth period of 178-183 days, which is 1-2 days later than that of the control 80Murray 8, with a plant height of 85-87 cm, erect seedlings, dark green leaves, vigorous growth, strong tillering ability, high panicle rate, rectangular panicle, no awn, white shell, full grain, red grain, half-cutin, and 1000-grain weight 45-50 g. The quality determination of Mianyang Grain Science Institute of the Ministry of Commerce showed that the grain wet gluten was 32.89%, the protein content was 14.31%, and the flour yield was 66%. 1%, unit weight 736g / L; strong drought resistance, lodging resistance, good yellowing conversion, easy threshing. Identified by the Institute of Plant Protection of the Provincial Academy of Agricultural Sciences in 1995: medium resistance to stripe rust, susceptibility to powdery mildew, leaf rust and scab, its resistance to stripe rust and powdery mildew is better than the control 80-8.
(3) yield performance: participated in the wheat regional test in Neijiang City in 1991 and 1992, with an average yield of 327 per mu. The average yield per mu in 1993 was 6.7% higher than that of Mianyang 11, which was 6.7% higher than that of Mianyang 11. In 1994, the average yield per mu was 312.25 kg, which was 4.0% higher than that of control 80-8. In 1992 and 1994, they participated in the production trials in Neijiang City and Leshan City, respectively, and increased their yields by 7.5% and 3.8% respectively.
(4) suitable planting area: suitable for planting winter wheat in similar ecological areas such as the hills of central Sichuan and northwest Sichuan.

There are techniques for late sowing wheat to create high yield.
Due to the late sowing time of late sowing wheat (wheat sown after mid-October, generally known as late sowing wheat), it is difficult to achieve complete, strong and uniform seedlings, so it is not easy to obtain high yield. But if properly managed, high production is also possible. The main results are as follows: (1) it takes 10 to 15 days for late sowing wheat with sufficient basic fertilizer from sowing to emergence, which shortens the growth time before winter and weakens the growth time of wheat seedlings in the soil. Late sowing wheat must apply sufficient base fertilizer, 3500 kg of high quality soil fertilizer, 40 kg of ammonium sulfate, 50 kg of superphosphate and 10 kg of potash fertilizer per mu.
