Longfumai 14 (formerly known as Longfu 93-127)

Breeding unit: Institute of crop breeding, Heilongjiang Academy of Agricultural Sciences

Variety source: F0 (Ke 86F6-545 / Hei 85-1584) γ 1.0Rad

Characteristics: spring, late ripening, the whole growth period is 92 days. The seedlings are erect and the leaves are light green. The plant height is 87 cm. Ear spindle type (La Budalin point is rectangular), awnless (Keshan @ # @ 245mm @ all points are top awn), white shell, red grain, hard. The average number of ears per mu is 372000 ears, the number of grains per ear is 26, and the weight of 1000 grains is 36.6g. It has good drought resistance, moisture resistance and lodging resistance. Inoculation resistance identification: slow stripe rust and leaf rust, medium resistance to root rot, high susceptibility to scab. In 2001 / 2002, the mixed samples were determined respectively: bulk weight 816g / L, protein content 14.03pm 13.92%, wet gluten content 29.4pm 29.2%, sedimentation value 28.5pm 30.9 ml, water absorption 63.6pm 62%, dough stability time 1.9pm 2.1 minutes, maximum extension resistance 120/242E.U, stretch area 22.8pm 42.6cm.

Yield performance: in 2000, participated in the preparatory test of the late ripening group of northeast spring wheat, the average yield per mu was 249.3 kg, which was 14% higher than that of the control Xinkehan 9; in 2001, the regional trial of the late mature group of northeast spring wheat showed an average yield of 236.9 kg per mu, which was 9.2% higher than that of the control Xinkehan 9; in 2002, the average yield per mu was 293.4 kg, 5.6% higher than that of Xinkehan 9. In the production test in 2003, the average yield per mu was 233.0 kg, which was 5.7% higher than that of the control Xinkehan 9.

Key points of cultivation techniques: it is required to prepare the soil in autumn and apply fertilizer in autumn to reach the state of waiting for sowing. The depth of base fertilizer applied in autumn is 10-12 cm, 2 beat 3 of the total fertilizer is applied, and the remaining 1 big 3 is used as seed fertilizer and topdressing during the growth period. The application of chemical fertilizer is about 11 kg per mu, N:P:K=1:1.1:0.3. There are 33-400000 seedlings per mu in the eastern part of Heilongjiang Province, and 40 plants in the western part of Heilongjiang Province and the Eastern fourth League of Inner Mongolia. Seeds should be coated. Press the green seedlings for 1-2 times at the three-leaf stage, control insects in time, top dressing at heading and flowering stage, and harvest at the right time. Pay attention to the prevention and control of scab.

Definite opinion: after examination, the variety conforms to the national wheat variety approval standard and has been approved. It is suitable to be planted in the middle and north of Heilongjiang in northeast spring wheat region and Dongsi League in Inner Mongolia.
