摘　　要：以PH6WC、郑58及8个郑58的改良系为试材,对改良系与郑58主要农艺性状进行比较。结果表明,部分改良系在植株性状与穗部性状方面明显优于郑58,其中改良系11177、11201综合性状明显好于郑58。改良系11145和11146的平均脱水速率分别比郑58增加了35.15%、39.13%。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.
