Moreover, Longchuang 3 10 maize varieties have mature living trees and full grain filling in the later stage, which provides a strong guarantee for high yield and harvest of summer maize.
In 202 1, Longchuang 3 10 maize still showed very good disease resistance, especially in the resistance to southern rust, which laid the foundation for high yield and bumper harvest of maize.
High lodging resistance
Longchuang 3 10 has a compact plant shape, with a plant height of 264 cm, a spike height of 96 cm and 19~20 leaves.
Moreover, this corn variety has good stem elasticity, strong toughness, developed root system, many aerial roots and outstanding lodging resistance.
Moreover, this jade variety has a low center of gravity and has not fallen down after many storms, which provides a guarantee for high yield.
Unified spike
Longchuang 3 10 corn has good close planting tolerance, large ears are sparsely planted, and close planting is full-headed, with no obvious marginal benefit.
The ear of this maize variety is tubular, the ear length is 17.6 ~ 19.7 cm, the longest is 26 cm, the rows per ear are 16~ 18, and the ear thickness is 4.9 cm.

Stable and high yield
This variety has good adaptability, strong disease resistance and strong disaster resistance, and has shown stable and high yield after years of planting. The average yield per mu of this maize variety is 1349 kg, and the highest yield per mu will reach 2020 kg in 2020.
202 1, although it was affected by many natural disasters such as drought in the early stage and heavy wind and rain in the later stage, the yield per mu still exceeded 2000 kg, which is a new maize variety with stable and high yield.
In the yield test, Longchuang 3 10 corn was planted in northeast and north China in spring, with an average yield of 749.9 ~ 767.5 kg per mu. The average yield per mu of summer sowing Longchuang 3 10 corn in Huanghuaihai was 634.5 ~ 674.5 kg, and the highest yield per mu was 1020 kg.
