Introduction of Longgao L2 Maize seed

Longgao L2 maize seed was bred by the High yield breeding Room of Maize Research Institute of Heilongjiang Academy of Agricultural Sciences and approved by Heilongjiang Variety examination and approval Committee in 2004. at present, the management right of this variety belongs to Heilongjiang Green Garden seed Industry. The characteristic of the maize seed is that the plant is about 2.7m high, the ear is cylindrical, the grain has about 18-22 rows, and the yield can reach more than 1000 kg under suitable cultivation conditions. It is a necessary variety for the high yield test of "small mu ton grain".

Variety characteristics

Corn seed L2 plant height is about 2.7m, ear position 120cm, ear cylindrical, grain 18Murray 22 rows, about 45 grains per row, 100-grain weight 35g, grain horse tooth type, orange yellow, bulk weight 751g, horny grain, suitable cultivation conditions, the yield can reach more than 1000 kg, it is a necessary variety for "small mu ton grain" high yield test.

The plant type of Longgao L2 is semi-convergent, so it has great comprehensive advantages in ventilation and light transmittance, high resistance to maize leaf spot, head smut, maize smut and bacterial wilt, strong main root, developed aerial root, stout stem, developed root system and sturdy stem. Longgao L2 has strong drought resistance and lodging resistance. The living stalk of Longgao L2 maize seed matured, and the stem remained dark green from early spring to late autumn.

The promotion scope of this variety has increased year by year in recent years, and its strong lodging resistance and high yield have been gradually recognized. In 2009, this variety still achieved a stable yield in some areas of Heilongjiang Province with continuous rain, low temperature and frequent hail disasters. In some areas, the planting area of this variety has reached 70% of the corn planting area in this area.

In 2010, a strong wind in Mishan area on August 14 blew down 90% of corn varieties, and a considerable number of corn varieties seriously reduced their yield, while Longgao L2 basically did not lodge, which shows that the lodging resistance is relatively strong.

In terms of yield, the high yield of Longgao L2 is outstanding. Statistics in recent years show that Longgao L2 has turned "small mu ton grain" into reality and become the norm.
