| 摘 要： | 选用生产上常用的9个玉米自交系，采用双列杂交的方式组配了36个杂交组合，研究了持绿性与其它农艺性状的关系。结果表明，绝对绿叶面积持续期(GLAD)与总叶片数、开花时绿叶面积以及相对GLAD呈显著或极显著正相关，通径分析结果表明开花时绿叶面积、相对GLAD这两个性状的直接效应较大；相对GLAD与开花时绿叶面积呈显著负相关，与茎秆硬度呈显著正相关；玉米持绿性提高，使收获时茎秆、叶片中的含水量提高，但不会引起籽粒含水量的提高。 |

| Abstract: | Thirty-six crosses are obtained with nine maize inbred lines by complete diallel. The relationship between their stay-green traits and other agronomic traits are studied. The results indicated that absolute green leaf duration is significantly and positively correlated with leaf number, green leaf area at flowering and relative green leaf area duration. The results of path analysis indicated that effects of green leaf area at flowering and relative green leaf area duration are more important. Relative green leaf area duration is significantly and negatively correlated with green leaf area at flowering, is significantly and positively correlated with hardness of stem. The improvement of stay-green can increase stem and leaf water content, but can't increase kernel water content. |
