Abstract：In order to explore the specific differences of domestic and abroad sweet corn hybrids,this experiment tries to have an analysis on 50 domestic and abroad sweet corn hybrids for their three kinds of main traits such as agronomic traits,grain traits and quality traits.The results of the experiment showed that the sweet corn hybrids in China were significantly higher than abroad hybrids in the plant height,ear height,stem diameter,number of stem node,number of leaves above the ear and harvest period(P＜0.05).The weight of harvested ear,net weight per ear,the ear length and the ear tip,kernel number per row and ear diameter of sweet corn hybrids in domestic were significantly higher than those of abroad hybrids(P＜0.05).However,the row number per ear was significantly lower than that of abroad hybrids(P＜0.05).Yet there was no significant difference in hundred-kernel weight and axial diameter between the two groups(P＞0.05).The sucrose content and taste score of domestic hybrids were significantly lower than those of abroad hybrids.However,the thickness of the seed capsule of sweet corn hybrids in China was significantly thicker than that of abroad hybrids(P＜0.05).
