摘　　要：利用江西宜春市农业科学研究所原育成的波里马细胞质雄性不育系291A与国内引进的双低常规油菜品系广泛测交,选择F1能保持不育的株系,用原父本与之回交,经春、夏两季连续6个世代成对回交,结合田间抗性调查及室内品质检测,育成了性状优良的双低不育系3A和其保持系3B。结果表明,新不育系3A具有不育性较彻底、抗性强、品质优、配合力高等优点,由3A配制的杂交组合杂363在江西省油菜区试中两年平均比对照增产12.40%,平均产量均排第一位。After extensive test cross of the originally bred polima cytoplasmic male sterile （CMS） line 291A with domestic double-low rapeseed lines, the maintainable sterile line F1 was selected and then backcrossed with the original male parent. Through six successive generations of paired backcross combining with the field resistance survey and indoor quality testing, CMS line 3A and maintainer 3B were obtained. CMS line 3A is completely sterile with strong resistance,good quality and high combining ability etc. Hybrid of 363 and CMS line 3A had average yield of 12.40%, higher than that of the control in regional trial in two years.
