摘要
利用泰安市农业科学研究所选育的优良雄性不育系ST039与自选系岱20组配成F1代完全不育的优良杂交种ST618。其杂种F1代为完全不育。掺和型雄性不育化杂交种的利用有二种方法:一是与同型可育杂交种按2∶1或1∶1掺合应用,利用同型可育杂交种的花粉给不育杂交种授粉;二是利用高油玉米花粉直感效应,雄性不育节养技术遗传效应和杂种优势利用效应三种遗传集成,提高普通玉米籽粒含油量。
Using the good male sterile line ST039 bred by Tai'an Institute of Agricultural Sciences crossed with the inbred line Dai20,then we got the good hybrid ST618,the F 1 generation of it were complete sterile. And there were two ways in the application of the mixed male sterility lines, the one is to mixed it with the same type fertile hybrids at the 2∶1 or 1∶1 proportion, then the fertile hybrid can be pollinate to the sterile hybrid, the other way is to combined the pollen xenia effect of the high oil maize ,the save nutrient effect of male sterility with the heterosis effect ,then improve the oil content of maize.
