Breeding unit: Zhang Shicheng, Chen Mingqing
Characteristics: It is a medium Late Maturing Maize Hybrid. Spring sowing in southern Shaanxi is about 117 days from maturity to maturity. Emergence to loose powder for 66 days, emergence to silking for 68 days, florescence coordination. The leaf sheath of seedling is light green and grows strong. The leaf number of the adult plant is 19-21, the leaf color is strong green, the transmittance is good, and the photosynthetic utilization rate is high. The plant type is semi compact, with a height of 290 cm and a spike height of 110 cm. There are 12-15 branches of male tassel, large pollen quantity and anther yellow. The upper leaves of the panicles are tall and the stem angles are small. The ears are long cylindrical, with a white cob, 22.6 cm long panicles, 16-18 rows of rows, 5.6 cm thick ears, 43.9 grains per row, 38.6 grams of 100 grain weight, and 87% seed yield. Grain yellow, half dentate. Live stalks are mature, have good green retention and strong lodging resistance. Resistance to disease: high resistance to stem rot, ear rot and small leaf spot, resistance to big leaf spot and head smut. The quality test showed that the bulk density was 794 grams / liter, crude protein content (dry basis) was 10.3%, crude starch content (dry basis) was 66.3%, crude fat content was 5.3%. Spring sowing is better in early April. Planting with plastic film or planting seedlings can be sowed 15 days in advance. Spring sowing monoculture 2600-2800 plants / mu, intercropping 2000-2200 plants / mu. Formula fertilization of nitrogen, phosphorus and potassium.
