| 摘 要： | 对24个玉米品种进行春播与夏播两种方式种植,研究春播与夏播两种播种方式对玉米品种特异性、一致性和稳定性(DUS)测试有关性状表达的影响。结果表明,玉米的果穗形状、果穗子粒颜色数量、果穗子粒排列形式和叶鞘花青甙显色强度4个性状表达不受播种方式的影响;抽丝期、散粉期、叶片宽度和果穗长度等4个性状表达受播种方式的影响明显;叶片弯曲程度等8个性状表达受播种方式的一定影响;雄穗花药花青甙显色强度等8个性状表达基本不受播种方式的影响。播种方式对玉米品种DUS测试性状表达有一定的影响。

| Abstract: | Twenty-four maize varieties were planted to study the differences of characteristics expressions in spring sowing and summer sowing. The results showed that the expressions of four characteristics such as the shape of ear were not affected by seeding methods. The other four characteristics such as time of ear silk emergence were highly influenced. Curvature of blade and other eight characteristics were moderately influenced. The other eight characteristics such as anthocyanin coloration of ear silks were very weakly influenced. Sowing methods had some influences on the expressions of maize DUS characteristics. |
