Abstract
Two crosses(0410×1155 and 0417×1025) were used for the study of inheritance model of several yield traits in micro-endosperm super-high oil corn.Combination analysis of six generations showed that the inheri-tance of ear length in two crosses fitted the model of polygenes.In cross 0410×1155,the inheritance of kernel weight per ear and 100-kernel weight fitted the model of polygenes.The inheritance of ear diameter fitted the model of one major gene plus polygenes,the inheritance of length of bald tip fitted the model of two major genes plus polygenes.In cross 0417×1025,the inheritance of ear diameter fitted the he model of polygenes,the inheritance of kernel weight per ear and length of bald tip fitted the model of one major gene plus polygenes,the inheritance of 100-kernel weight fitted model of two major genes plus polygenes.
