Introduction to the Longfumai 14 (formerly Longfu 93-127) wheat variety
Breeding institution: Crop Breeding Research Institute, Heilongjiang Academy of Agricultural Sciences
Variety source: F0 (Ke 86F6-545/Hei 85-1584) γ1.0Rad
Characteristics: spring type, late maturing, whole growth period 92 days. Seedlings erect, leaf color light green. Plant height 87 cm. Spike spindle-shaped (rectangular at the Labudalin site), awnless (tip-awned at the Keshan @#@245@#@ Institute site), white glume, red grain, hard texture. Average number of spikes per mu 372,000 spikes, grains per spike 26, 1000-grain weight 36.6 g. Relatively good drought resistance, good moisture tolerance, good lodging resistance. Inoculated disease resistance identification: slow stripe rust and leaf rust, moderately resistant to root rot, highly susceptible to scab. 2001/2002 mixed samples tested respectively: test weight 816 g/L, protein content 14.03/13.92%, wet gluten content 29.4/29.2%, sedimentation value 28.5/30.9 mL, water absorption 63.6/62%, dough stability time 1.9/2.1 minutes, maximum resistance to extension 120/242 E.U, extensibility area 22.8/42.6 sq cm.
Yield performance: In 2000, participated in the preliminary trial of the late-maturing group of Northeast spring wheat, average yield per mu 249.3 kg, an increase of 14% over the control Xinkehan 9; in 2001, participated in the regional trial of the late-maturing group of Northeast spring wheat, average yield per mu 236.9 kg, an increase of 9.2% over the control Xinkehan 9; in 2002, continued the trial, average yield per mu 293.4 kg, an increase of 5.6% over the control Xinkehan 9. In 2003, the production trial average yield per mu 233.0 kg, an increase of 5.7% over the control Xinkehan 9.
Key cultivation techniques: Autumn land preparation required, autumn application of manure, to reach a ready-to-sow state. The depth of autumn basal fertilizer application is 10-12 cm, applying 2/3 of the total fertilizer amount, with the remaining 1/3 used as seed fertilizer and topdressing during the growth period. Apply about 11 kg of chemical fertilizer per mu, N:P:K=1:1.1:0.3. Seedling stand per mu: 330,000-400,000 plants in eastern Heilongjiang, 40 plants in western Heilongjiang and the four eastern leagues of Inner Mongolia. Seeds should be coated. Press the green seedlings 1-2 times at the three-leaf stage, control pests in time, foliar topdressing can be applied at the heading and flowering stage, and harvest at the appropriate time. Pay attention to the prevention and control of scab.
Final opinion: Upon review, this variety meets the national wheat variety approval standards and has passed approval. It is suitable for planting in medium-fertility land in central and northern Heilongjiang and the four eastern leagues of Inner Mongolia in the Northeast spring wheat region.
