Abstract: Twelve agronomic traits and 4 resistant traits of 42 waxy corn cultivars certified during 2000 to 2013 in Zhejiang Province were analyzed， and their evolutional analysis and correlations were also discussed. The results showed that the yield of waxy corn cultivars certified exhibited a significantly upward trend， with an average annual increase of 2259 kg·hm-2. Compared with the control， the growth period of cultivars delayed 0429 d annually. Amylose content showed a significantly downward trend， with an average annual decrease of 0048%. Single panicle weight rose significantly with an average annual increase of 455 g， and there was no significant difference in other agronomic traits such as growth period， plant height， ear height， ear length， ear diameter， number of lines per row， bald， and weight in the approved varieties among years. Further analysis indicated that the correlation coefficient of traits and yield was decreased in the order of ear length > growth period > single panicle weight > plant height > ear diameter > kernels per row > rows per ear > ear height > thousand seed weight > bald， and there was a significant positive correlation between single panicle weight， plant height， ear diameter， kernels per row and yield. For the high yield breeding of waxy corn varieties in Zhejiang Province， germplasm innovation was urgently needed， and efforts should be focused on the selection of ear length and ear diameter. The amylose content should be further reduced， and the growth period should be appropriately extended to achieve ideal yield．
