螟虫是危害水稻生产的重要虫害，长江中下游稻区尤以二化螟发病较多，对水稻稳产、增产造成较大影响。研究以转Cry1Ab基因抗虫恢复系mfb-MH86为供体，强优恢复系HR1128为受体，通过田间回交转育，结合分子标记检测、农艺性状筛选得到抗虫恢复系新材料KR1128-1、KR1128-2和KR1128-3。产量性状分析结果表明，改良恢复系与非转基因对照HR1128相比，株高显著降低，但单株有效穗数有所改善，均显著高于HR1128；改良恢复系的结实率均略高于亲本HR1128，以KR1128-3的结实率最高（82.0%）。在稻米品质上，改良新株系与HR1128多数指标无显著差异，少数性状稍有改善，如KR1128-3在整精米率、垩白面积和垩白...
