玉米进一步自交前的测交选择：平均表现与现实遗传方差ＲｅｘＢｅｒｎａｒｄｏ系谱选择是用于产生玉米自交种最常用的育种方法。Ｆ２代的分离群体或回交群体通过自交、对穗行后代进行目测选择，并结合无亲缘关系的自交测验种进行测产，从而产生新的自交种。系谱选择的目的... Maize selection prior to further selfing: Average performance versus actual genetic variance RexBernardo pedigree selection is the most commonly used breeding method for producing maize inbreds. F2 generation of segregating populations or backcross populations were self-crossed to make visual selection of the offspring of the ear lines, and the non-related self-breeding test varieties were used for the yield measurement to generate new self-crossings. The purpose of pedigree selection ...
