The average growth period of summer sowing in Beijing is 107 days. Compact plant type, plant height 246. 1cm, ear position 99.0cm, and empty stalk rate 2.0%. The spike is tubular, the spike axis is white, the spike length is 17.9 cm, the spike thickness is 5.4 cm, the bald tip length is 0.2 cm, the rows per spike are 12- 16, and the number of grains per row is 34.9. Grain weight per spike173.0g, and seed yield was 80.3%. The grain is yellow and semi-hard, with a grain depth of 65438 0.2 cm and a 1000-grain weight of 397.6 grams. Grain (dry basis) contains crude protein 8.23%, crude fat 3.84%, crude starch 74.47%, lysine 0.27%, and bulk density 742 g/L. Inoculation and identification show that it is resistant to leaf spot, leaf spot, Curvularia leaf spot, high sensitivity dwarf mosaic disease and stem rot.
Field yield performance of maize seeds;
The average yield per mu in the two-year regional trial was 707.0 kg, which was 9.6% higher than that of the control single crystal 28. The average yield per mu in production test is 669.9 kg, which is 20.3% higher than that of the control single crystal 28.
Key points of field cultivation techniques for maize seeds;
The planting density is about 4500 plants per mu in plots with medium fertility or above. Use with caution in areas with high incidence of stem rot.
