| Abstract: | Agronomic traits of improved lines and Zheng58 were compared using PH6WC, Zheng58 and its eight improved lines as experimental materials. The results showed that plant traits and panicle traits of some improved lines were significantly better than that of Zheng58, and comprehensive characters of improved lines 11177 and 11201 were both better than that of Zheng58 significantly. The average dehydration rates of improved lines 11145 and 11146 increased by 35.15% and 39.13% than Zheng58, respectively. |
