【摘要】 转基因抗虫玉米是控制危害玉米生产的玉米螟的新方法。本文就此对常规自交系进行抗虫性改良 ,转基因供体材料较常规自交系具有较高抗性。中度抗性材料对于玉米螟反应弹性比较大 ,容易受到大的危害。在转育世代中 ,抗性植株出现的比例较少 ,需要进行细致选择更多还原

【Abstract】 s:The transgenic technology now acts as a new method to control the maize borer The resistant gene was introduced into several elite inbred lines by backcross The lines with resistant gene have higher resistant than those not The mid-resistant lines have wide-range response to maize borer Careful selection should be taken to screen the resistant individual plants during the backcross generations更多还原
