摘要:
对合344及其21个衍生自交系的6个株型相关性状进行方差分析和因子分析，旨在研究合344及其衍生自交系的株型性状的差异及相关性。结果表明：合344及其衍生系之间株型性状差异显著，株高、穗位高和雄穗长度呈正相关，而与雄穗分支数和叶向值呈负相关。合344衍生系株型向紧凑型发展。叶向值大的自交系，可获得更多的雄穗分枝。玉米自交系单交可以显著提高株高、穗位高、雄穗分枝数与叶向值。
Abstract:
Variance analysis and factor analysis on six plant type related traits of He 344 and derivative inbred lines were carried out to study the differences and correlation of He 344 and derivative inbred lines.The results showed that there was significant difference plant type related traits between He 344 and derivative inbred lines,there was positively correlated with plant height,spike height and tassel length and negatively correlated with the tassel branch number and leaf orientation value.The plant type of He 344 inbred lines was developed to compact type.The lines with large leaf orientation value obtained more tassel branch.Maize inbred line single cross could significantly improve plant height,spike height,tassel branch and leaf orientation value.
