A comparative test of 5 new cuhivars of fresh-eating sweet maize was carried out. The results showed that Yuetian No. 22, Yuetian No. 16 and Yuetian No. 21 have high fresh ear yields （1 118 kg, 1 079 kg, 1 012 kg, respectively）, their ear quality and out-looking appearance were also better with a promising prospect for further application. Yuetian No. 23 performances moderate plant height and one spike, and could be closely planted to achieve a high yield; Hangtian No. 2 was suitable for close planting and fresh-eating because of its bigger ear, sweeter grains, thinner skin without dregs, and the best eating quality.
