| 摘 要： | 2004～2006年利用两个玉米单交组合的P1、P2、P3、P4、F1、F2、B1.1、B1.2和B1.2、B1.2 10个世代群体的数据进行了世代平均数分析。估算了a、d、aa、ad和dd各类基因效应及其相应的方差及平方和百分比.分析表明，世代间有显著差异，其差异大小取决于杂交双亲。穗行数的加性效应比例占70．47％，穗轴粗的加性效应比例占59．99％；穗粒数的显性率最高（51．51％），其次是加性效应（37．15％）。穗行数、穗粒数和穗轴粗的上位效应分别占11．98％、11．34％和32．75％。可见，上位效应对果穗经济性状的遗传在育种研究中也不能忽视。

| Abstract: | From 2004 to 2006,two F1 maize hybrids,F2s,backcrosses B1s and B2s and their parents were used to estimate the generation means for diameter of the ear axis,and the rows per ear and grains per ear.Estimate of gene effects and of varience,including a,d,aa,ad and dd were obtained.The results showed that there were significant differences for each of the three traits among generation means,and the differences varied with their parents.The additive component was 70.47% for the rows per ear,the additive componen... |
