| 摘 要： | 利用小麦三个单交组合的 P_1、P_2、F_1、F_2,B_1和 B_2六个世代群体以及一套双列杂交材料,根据3种不同模式,估算了各类基因效应、杂种优势和配合力等遗传参数。研究对比了不同遗传模式;分析了各类基因效应,尤其是上位效应的特点。根据基因效应分析了杂种优势的遗传组成,结果认为显性效应及 aa 型上位效应对杂种优势起重要作

| Abstract: | Using six generation populations in each of three single crosses and a set of6×6 diallel crosses of wheat,each kind of gene effects,heterosis and combiningability were estimated by three genetic models proposed by Hayman,Mather and Jinks,and Gardner and Eberhart,respectively.Comparison among the th |
