Taking domestic maize varieties Limin33, Nonghua101, Xinxin1 and Xinxin 2 as experiment materials,Xianyu 335 as the check variety, the differences of yield and agronomic characters of different maize varieties were comparative studied. The results showed that yield of check variety Xianyu335 was steady, but its resistance to lodging was weaker, so it was easy to lodge. The yields of Limin33, Xinxin 1 and Xianyu335 were not significant different with Xianyu335, but the yield of Xinxin 2 was significantly lower than Xianyu335. Plant height and ear height of Xinxin series variety were lower, their LAI were lower too. LAI and harvest index of Limin33 was higher, but its single plant dry matter accumulation was lower. Nonghua101 had significantly advantages in yield which reached 1 ton/mu grain, which LAI, single plant dry matter accumulation and stem lodging resistance was super, so it had high potential production in the eastern humid region of Jilin Province.
