See the corn varieties that are resistant to high temperatures, rust, and collapse, such as Dudan 5, Zhengdan 958, Lonchon 310, Hanshan 777, Jiaxi 100, Qihua 703, and Denghai 605. Among them, Longchuang 310 corn plant compact, plant height of 264 cm or so, the cob is cylindrical, cob axis red, cob rows of 14-16 rows, kernels are yellow, half-marshall type, 100 grain weight of 36.9 grams, in the resistance to the southern rust, tassel rot disease and other diseases.

Maize southern rust, stem rot and tassel rot disease three major diseases, the occurrence of year after year, has become the most common in the growth of maize in the late stages of the most serious damage to the three major diseases, the choice of high resistance to these three major diseases of maize varieties of new maize, maize is the premise of the high yield and guarantee.

The main characteristics of the varieties

1, the short stem of resistance to fall: Weiyu 718 average plant height of 244 cm, spike height of 95 ~ 103 cm, compact, spike above the leaf upward, the base of the short internode, the root system is well developed, aerial roots multi-layered, strong resistance to fall, especially in the performance of the year 2021 outstanding.

2, high resistance to dense planting: Weiyu 718 general planting density of 4,500 to 5,000 plants per acre, the highest can be planted 6,000 plants, not empty, not flower grain, not bald tip, fruiting is very good, sparse planting spike large, dense planting yield is high.

3, high resistance to three major diseases: identified by inoculation and field performance, Weiyu 718 is highly resistant to corn southern rust, stem rot and tassel rot, at the same time, there is a certain resistance to corn borer. Live tree maturity, long standing pole time, good field ventilation and light transmission, long seed filling time, suitable for mechanical harvesting.
