AbstractTo compare the variety characteristics of 12 sweet maizes such as Jintianshun 1OO， Huitian 138，and Zhenzhenbang 6，arandom block design was adopted to determine their agronomic traits such as plant height，panicle length and other panicle traits，as well aspanicle weight and other yield traits.Correlation analysis among these traits was also conducted.The results showed that there were significantdiferences in traits such as plant height，ear position height，earlengthandear thicknessof the tested varieties.Among them，theplant heightof maizeranged from 206.2 to 325.6 cm，the ear position height ranged from 66.O to 180.4 cm，the empty stalk rate ranged from O to 12.8% ，and the double ear rate ranged from 1.6% to 22.4% . The length of the panicle ranges from 20.50 to 23.46 cm， the diameter of the panicle was from 20.40 to 23.67cm，the length of the balding tipwas from 0.66 to 2.88cm，the number ofrows of the paniclewas from13.2to20.4，and the numberof grains ineachrow is from38.3to48.8.The panicle weightranged from 266.80 to 368.65 g，the weight per hundred grains ranged from 31.85 to 47.76g ，theyield ranged from 8 979.48 to 14 391.56kg/hm2 ，and the seed yield ranged from 56.42% to 87.00% . The correlation analysis indicated that there was a positivecorrelation between thelength and thicknessof sweet maizeears，thenumberofrows and the positionof the ears，the plantheightandthe heightof theears，the thicknessoftheearsandthe yield，thenumberofrowsandthe plant height，andthe weight oftheears andtheyield.Overall，theagronomic traitsof Zhenzhenbang No.6are generallygood， andthe yieldofJinguang 597 was the highest.This article provides areferenceforthe breeding of highyield sweet corn varieties.
